working with an ADT message template in Mirth, having issues with the IN1 and IN2 segments, the IN2 specifically.
Here's a sample message that I'm working with, removed almost all the segments.
MSH|^~&|EPIC|AMB||99|20220403165344|RELEASEAUTO|ADT^A04|367476|T|2.5|||AL|NE

IN2|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||second iteration IN1-62||
So far I've built the following to iterate over the IN1 segment:
//IN1 Segments
var IN1count=0;
for each (seg in msg.IN1) {
createSegment('IN1',output,IN1count);
output.IN1[IN1count]['IN1.2'] = seg['IN1.2'];
output.IN1[IN1count]['IN1.3'] = seg['IN1.3'];
output.IN1[IN1count]['IN1.4'] = seg['IN1.4'];
output.IN1[IN1count]['IN1.8'] = seg['IN1.8'];
output.IN1[IN1count]['IN1.9'] = seg['IN1.9'];
output.IN1[IN1count]['IN1.10'] = seg['IN1.10'];
output.IN1[IN1count]['IN1.12'] = seg['IN1.12'];
output.IN1[IN1count]['IN1.13'] = seg['IN1.13'];
output.IN1[IN1count]['IN1.22'] = seg['IN1.22'];
output.IN1[IN1count]['IN1.36'] = seg['IN1.36'];
IN1count++;
}
I'm struggling to map the IN2 segment correctly on the outbound, I've read about getSegmentsAfter but I can't find that function online... how do I write the correct JS code to look for whether the given IN1 has an IN2 after, specifically if it has IN2-61, and only then create the IN2 segment?
Hope that makes sense :)
You'll find code for createSegmentAfter here; it is JavaScript inserted before your transformer: https://github.com/nextgenhealthcare/connect/blob/2f3740db44c8d42aa6fafffd991b9c1fde940ea0/server/src/com/mirth/connect/server/builders/JavaScriptBuilder.java
One approach to keeping track of whether you just passed an IN1 would be to loop over all segments with something like this:
var was_in1 = false;
var last_in1;
for each ( seg in msg.children() ){
if (was_in1) {
if (seg.name() == "IN2") {
// existing IN2 follows IN1
} else {
// insert new IN2
}
if (seg.name() == "IN1") {
was_in1 = true;
last_in1 = seg;
} else {
was_in1 = false;
}
}
It'd be nice if there was a "nextSibling()" method for messages, but there isn't. Luckily, we can simulate it by:
Getting the current object's childIndex
Getting all children from the current object's parent
Access the next child with the index childIndex + 1
It'd look like this:
for each (seg in msg.IN1) {
// Do your IN1 stuff ...
var nextSeg = seg.parent().children()[ seg.childIndex() + 1];
if(nextSeg != null && nextSeg.name() == 'IN2' && nextSeg['IN2-61'].toString() != '') {
// Do yourIN2 stuff ...
}
}

I have frames that are delimited by bytes to start and stop the frame (they do not appear in the stream).
I read a chunk from disk or network socket, i then need to pass to a deserializer but only after I have de-framed the packet first.
Frames may span multiple chunks that have been read, note how frame 3 is split across array 1 and array 2.
Rather than reinvent the wheel for this common problem, do any github or similar projects exist?
I am investigating ReadOnlySequenceSegment<T> from https://www.codemag.com/article/1807051/Introducing-.NET-Core-2.1-Flagship-Types-Span-T-and-Memory-T and will post updates as I work out the requirements.
Update
Further to Stephen Cleary link (thank you!!) to https://github.com/davidfowl/TcpEcho/blob/master/src/Server/Program.cs I have the below.
My data is json, so unlike the original question the delimiter tokens will appear in the stream. Therefore I have to count the array delimitator and only declare a frame when i have found the outermost [ and ] characters.
The below code works, and less manual copies done (not sure if still done behind the scenes - code is quite neater using David Fowl approach).
However I am casting to array instead of using buffer.PositionOf((byte)'[') since I was unable to see how I could call the PositionOf with an offset applied (i.e. scan deeper into the frame past previously found delimiter tokens).
Am i using/butchering the library in a brute force way, or is the below good to go with the array cast?
class Program
{
static async Task Main(string[] args)
{
using var stream = File.Open(args[0], FileMode.Open);
var reader = PipeReader.Create(stream);
while (true)
{
ReadResult result = await reader.ReadAsync();
ReadOnlySequence<byte> buffer = result.Buffer;
while (TryDeframe(ref buffer, out ReadOnlySequence<byte> line))
{
// Process the line.
var str = System.Text.Encoding.UTF8.GetString(line.ToArray());
Console.WriteLine(str);
}
// Tell the PipeReader how much of the buffer has been consumed.
reader.AdvanceTo(buffer.Start, buffer.End);
// Stop reading if there's no more data coming.
if (result.IsCompleted)
{
break;
}
}
// Mark the PipeReader as complete.
await reader.CompleteAsync();
}
private static bool TryDeframe(ref ReadOnlySequence<byte> buffer, out ReadOnlySequence<byte> frame)
{
int frameCount = 0;
int start = -1;
int end = -1;
var bytes = buffer.ToArray();
for (var i = 0; i < bytes.Length; i++)
{
var b = bytes[i];
if (b == (byte)'[')
{
if (start == -1)
start = i;
frameCount++;
}
else if (b == (byte)']')
{
frameCount--;
if (frameCount == 0)
{
end = i;
break;
}
}
}
if (start == -1 || end == -1) // no frame found
{
frame = default;
return false;
}
frame = buffer.Slice(start, end+1);
buffer = buffer.Slice(frame.Length);
return true;
}
}
do any github or similar projects exist?
David Fowler has an echo server that uses Pipelines to implement delimited frames.
I have a special class Model that needs to have its methods called in a very specific order.
I tried doing something like this:
val model = new Model
new MyWrappingClass {
val first = model.firstMethod()
val second = model.secondMethod()
val third = model.thirdMethod()
}
The methods should be called in the order listed, however I am seeing an apparently random order.
Is there any way to get the variable initialization methods to be called in a particular order?
I doubt your methods are called in the wrong order. But to be sure, you can try something like this:
val (first, second, third) = (
model.firstMethod(),
model.secondMethod(),
model.thirdMethod()
)
You likely have some other problem with your code.
I can run 100 million loops where it never gets the order wrong, as follows:
class Model {
var done = Array(false,false,false);
def firstMethod():Boolean = { done(0) = true; done(1) || done(2) };
def secondMethod():Boolean = { done(1) = true; !done(0) || done(2) };
def thirdMethod():Boolean = { done(2) = true; !done(0) || !done(1) };
};
Notice that these methods return a True if done out of order and false when called in order.
Here's your class:
class MyWrappingClass {
val model = new Model;
val first = model.firstMethod()
val second = model.secondMethod()
val third = model.thirdMethod()
};
Our function to check for bad behavior on each trial:
def isNaughty(w: MyWrappingClass):Boolean = { w.first || w.second || w.third };
A short program to test:
var i = 0
var b = false;
while( (i<100000000) && !b ){
b = isNaughty(new MyWrappingClass);
i += 1;
}
if (b){
println("out-of-order behavior occurred");
println(i);
} else {
println("looks good");
}
Scala 2.11.7 on OpenJDK8 / Ubuntu 15.04
Of course this doesn't prove it impossible to have wrong order, only that correct behavior seems highly repeatable in a fairly simple case.
In the following image you can see where i put the breakpoint and then debugged two step. You can also see that both assignments worked great they have the same count and are the same.
However if I do the following. Run the exact same call but only break on the third line directly then this happnes
set.QuestionSet.Questions should have count of 8 BEFORE the assigment, so it seems it's not properly assigned for some reason. I suspect this has something to do with how I fetch my data from DB.
Question and QuestionSet are normal POCOs and here is the code for the entire method.
public IEnumerable<QuestionSet> SearchAndFilterQuestionsAndSets(string searchString, int nrPerPage, int page, out int totalSearchCount)
{
searchString = searchString.ToLower();
List<QuestionSet> finalList = new List<QuestionSet>();
var result = ActiveContext.QuestionSets
.Select(x => new
{
QuestionSet = x,
Questions = x.Questions.Where(
y =>
y.Description.ToLower().Contains(searchString)
).OrderBy(
z => z.Description
)
})
.ToList();
foreach (var set in result)
{
//If our search matched the set itself we load all questions
if (set.QuestionSet.Name.ToLower().Contains(searchString))
{
//we dont bring empty sets
if (set.QuestionSet.Questions.Count() > 0)
{
set.QuestionSet.Questions = set.QuestionSet.Questions.ToList<Question>().OrderBy(x => x.Description).ToList<Question>();
finalList.Add(set.QuestionSet);
}
}
//We had one or more questions matching the search term
else if (set.Questions.Count() > 0)
{
var b = set.Questions.ToList<Question>();
set.QuestionSet.Questions = set.Questions.ToList<Question>();
finalList.Add(set.QuestionSet);
}
}
totalSearchCount = finalList.Count();
return finalList.Skip((page - 1) * nrPerPage).Take(nrPerPage);
}
UPDATE
If I do this instead in the failing else if
var a = new QuestionSet();
a.Id = set.QuestionSet.Id;
a.Name = set.QuestionSet.Name;
a.Questions = set.Questions.ToList<Question>();
finalList.Add(a);
Then it works, so the problem lies within the anonymous object, but why does it work when i step through with debugger and not otherwise?? call me puzzled.
Could be something to do with Late binding of anonymous types
I have a queue of elements, sorted by date. I need to extract the first n elements, which have the same date and add them to a temporary ArrayList, from which I choose one of them and scrap the others. After that I need to continue doing the same thing for the next n elements of the queue with the same date (extract them to the temp list and so on) until I have no more items in the queue.
// some notes to help you understand the code
PriorityQueue<Results> r, size(4), elementsEqualByTime(1=2,3=4);
List<Comments> c, size(2);
ArrayList temp;
if (c.size() != r.size() && resultIter.hasNext()) {
//first iteration will compare element 0 to itself -> 100% true
ResultObject r2 = resultIter.next();
ResultObject r1 = r2;
while (resultIter.hasNext() && r1.getTime().equals(r2.getTime())) {
temp.add(r1);
//we add the matching elements before we continue
r1 = r2;
temp.add(r1);
if (resultIter.hasNext()) {
//after we add the 2 matching elements we continue
r2 = resultIter.next();
}
}
//use the items in temp
temp.clear();
}
Right now it works for the 1st set of elements, but on the 2nd iteration it adds no elements to the temp ArrayList. I'd appreciate help with this solution, but am also open to different suggestions.
boolean Check (List<Element> elements,Element element)
{
for(Element element1:elements)
if(element1.equals(element))
return true;
return false;
}
void Stuff()
{
// some notes to help you understand the code
PriorityQueue<Element> r = new PriorityQueue<Element>();
List<Element> c;
List<Element> temp = new ArrayList<Element>();
for(Element element:r)
{
if(!Check(temp, element))
{
// do stuff with temp
temp = new ArrayList<Element>();
}
temp.add(element);
}
}
while (commentIter.hasNext()) {
Comment c1 = null;
temp.add(arrayQueue[0]);
for (int i = 1; i < arrayQueue.length; i++) {
if (!arrayQueue[i].getTime().equals(arrayQueue[i - 1].getTime())) {
c1 = commentIter.next();
//do stuff with the results
temp = new HashSet<ResultObject>();
}
temp.add(arrayQueue[i]);
}
if (!temp.isEmpty()) {
c1 = commentIter.next();
//do stuff with the results
}
temp = new HashSet<ResultObject>();
}
That's a tested solution which works.
I am trying to find a specific element from my page using ExtJS 4 so I can do modifications on it.
I know its id so it should not be a problem BUT
-I tried Ext.getCmp('theId') and it just return me undefined
-I tried to use down('theId') method by passing through the view and I still get a nullresponse.
As I know the id of the element I tried again the two methods by setting manually the id and it didn't work neither.
Do these two methods not function?
How should I do?
Here is the concerned part of the code :
listeners: {
load: function(node, records, successful, eOpts) {
var ownertree = records.store.ownerTree;
var boundView = ownertree.dockedItems.items[1].view.id;
var generalId = boundView+'-record-';
// Add row stripping on leaf nodes when a node is expanded
//
// Adding the same feature to the whole tree instead of leaf nodes
// would not be much more complicated but it would require iterating
// the whole tree starting with the root node to build a list of
// all visible nodes. The same function would need to be called
// on expand, collapse, append, insert, remove and load events.
if (!node.tree.root.data.leaf) {
// Process each child node
node.tree.root.cascadeBy(function(currentChild) {
// Process only leaf
if (currentChild.data.leaf) {
var nodeId = ""+generalId+currentChild.internalId;
var index = currentChild.data.index;
if ((index % 2) == 0) {
// even node
currentChild.data.cls.replace('tree-odd-node', '')
currentChild.data.cls = 'tree-even-node';
} else {
// odd node
currentChild.data.cls.replace('tree-even-node', '')
currentChild.data.cls = 'tree-odd-node';
}
// Update CSS classes
currentChild.triggerUIUpdate();
console.log(nodeId);
console.log(ownertree.view.body);
console.log(Ext.getCmp(nodeId));
console.log(Ext.getCmp('treeview-1016-record-02001001'));
console.log(ownertree.view.body.down(nodeId));
console.log(ownertree.view.body.down('treeview-1016-record-02001001'));
}
});
}
}
You can see my console.log at the end.
Here is what they give me on the javascript console (in the right order):
treeview-1016-record-02001001
The precise id I am looking for. And I also try manually in case...
h {dom: table#treeview-1016-table.x-treeview-1016-table x-grid-table, el: h, id: "treeview-1016gridBody", $cache: Object, lastBox: Object…}
I checked every configs of this item and its dom and it is exactly the part of the dom I am looking for, which is the view containing my tree. The BIG parent
And then:
undefined
undefined
null
null
Here is the item I want to access:
<tr role="row" id="treeview-1016-record-02001001" ...>
And I checked there is no id duplication anywhere...
I asked someone else who told me these methods do not work. The problem is I need to access this item to modify its cls.
I would appreciate any idea.
You are looking for Ext.get(id). Ext.getCmp(id) is used for Ext.Components, and Ext.get(id) is used for Ext.dom.Elements. See the docs here: http://docs.sencha.com/extjs/4.2.1/#!/api/Ext-method-get
Ok so finally I used the afteritemexpand listener. With the ids I get the elements I am looking for with your Ext.get(id) method kevhender :).
The reason is that the dom elements where not completely loaded when I used my load listener (it was just the store) so the Ext.get(id) method couldn't get the the element correctly. I first used afterlayout listener, that was correct but too often called and the access to the id was not so easy.
So, here is how I did finally :
listeners: {
load: function(node, records, successful, eOpts) {
var ownertree = records.store.ownerTree;
var boundView = ownertree.dockedItems.items[1].view.id;
var generalId = boundView+'-record-';
if (!node.tree.root.data.leaf) {
// Process each child node
node.tree.root.cascadeBy(function(currentChild) {
// Process only leaf
if (currentChild.data.leaf) {
var nodeId = ""+generalId+currentChild.internalId;
var index = currentChild.data.index;
if ( (index % 2) == 0 && ids.indexOf(nodeId) == -1 ) {
ids[indiceIds] = nodeId;
indiceIds++;
}
console.log(ids);
}
});
}
},
afteritemexpand: function( node, index, item, eOpts ){
/* This commented section below could replace the load but the load is done during store loading while afteritemexpand is done after expanding an item.
So, load listener makes saving time AND makes loading time constant. That is not the case if we just consider the commented section below because
the more you expand nodes, the more items it will have to get and so loading time is more and more important
*/
// var domLeaf = Ext.get(item.id).next();
// for ( var int = 0; int < node.childNodes.length; int++) {
// if (node.childNodes[int].data.leaf && (int % 2) == 0) {
// if (ids.indexOf(domLeaf.id) == -1) {
// ids[indiceIds] = domLeaf.id;
// indiceIds++;
// }
// }
// domLeaf = domLeaf.next();
// }
for ( var int = 0; int < ids.length; int++) {
domLeaf = Ext.get(ids[int]);
if (domLeaf != null) {
for ( var int2 = 0; int2 < domLeaf.dom.children.length; int2++) {
if (domLeaf.dom.children[int2].className.search('tree-even-node') == -1){
domLeaf.dom.children[int2].className += ' tree-even-node';
}
}
}
}
},
With ids an Array of the ids I need to set the class.
Thank you for the method.
