I'm working on a new application and i need to make a messages interface with lookup, using the key to find the value (like ConstantsWithLookup, but capable to receive parameters). I have being investigating Dictionary class functionality but it lacks message customization through parameters.
With ConstantsWithLookup i can make the following:
myConstantsWithLookupInterface.getString("key");
and get something like:
Field must be filled with numbers
But i need to do this:
myMessagesWithLookupInterface.getString("key", "param1", "param2",...);
and get something like:
Field _param1_ must be filled with numbers greater than _param2_
I have no clue how to do this.
Use GWT regular expressions:
//fields in your class
RegEx pattern1 = RegEx.compile("_param1_");
RegEx pattern2 = RegEx.compile("_param2_");
public String getString(String key, String replace1, String replace2){
// your original getString() method
String content = getString(key);
content = pattern1.replace(content,replace1);
content = pattern2.replace(content,replace2);
return content;
}
If your data contains Field _param1_ must be filled with numbers greater than _param2_ then this will replace _param1_ with content of string replace1.

I am trying to compare two jsons, expected and the API Response using Javers, as part of testing. I want the comparison to exclude the ID parameters that are dynamically generated by response.
My VO is like
public class expectedResponse{
#DiffIgnore
private String id;
private String name;
}
Both my expectedResponse- which is read from excel file and the actual response from API are deserialized into this format and then both the responses are compared.
JsonNode expectedOutput = mapper.readTree(expected.toString());
JsonNode apiResponse = mapper.readTree(actual.toString());
diff=javers.compare(expectedOutput, apiResponse);
But this comparison doesn't exclude/ignore the ID field. Any Idea how I can get it to work? I want only the ID field excluded in comparison results, diff in name should be listed.
Also question 2> I am trying to list the changes from diff
if (diff.hasChanges())
{
List<ValueChange> changes=diff.getChangesByType(ValueChange.class);
for (ValueChange change : changes)
{
logger.info(change.getPropertyName()+ "||" +change.getLeft().toString() + "||" +change.getRight().toString());
change.getPropertyName()- doesnt print the property's name but simply prints "_value" as its value.
Can you pls help in identifying what is going wrong with the code and how can I get this fixed? I am not finding much useful documentations about Javers anywhere in google. Any help is appreciated.
You should compare you domain object instead of object with JsonNode class, look that #DiffIgnore annotation is present only in your domain class and there is no connection between JsonNode and ExpectedResponse, thats why Javers doesn't know to ignore this field.
To summarise, your code should looks like this:
ExpectedResponse expectedOutput = ...
ExpectedResponse apiResponse = ...
diff=javers.compare(expectedOutput, apiResponse);
I am writing a translator which converts DSL to multiple programming language (It seems like Apache Thrift).
For example,
// an example DSL
LOG_TYPE: COMMERCE
COMMON_FIELD : session_id
KEY: buy
FIELD: item_id, transaction_id
KEY: add_to_cart
FIELD: item_id
// will be converted to Java
class Commerce {
private String session_id
private String key;
private String item_id;
private String transaction_id
// auto-created setter, getter, helper methods
...
}
It also should be translated into objective-c and javascript.
To implement it, I have to replace string
// 1. create or load code fragments
String variableDeclarationInJava = "private String {$field};";
String variableDeclarationInJavascript = "...";
String variableDeclarationInObjC = "...";
// 2. replace it
variableDeclarationInJava.replace(pattern, fieldName)
...
Replacing code fragment in String is not type safe and frustrating since it does not any information even if there are errors.
So, my question is It is possible to parse String at compile time? like Scala sqltyped library
If it is possible, I would like to know how can I achieve it.
Thanks.
As far, as I understand, it could be. Please take a look at string interpolation. You implement a custom interpolator, (like it was done for quasi quotations or in Slick).
A nice example of the thing you may want to do is here
I am using dotnetrdf and trying to parse some triples with NTriplesParser. I have my own handler RobHandler in which I process each triple in turn.
public class RobHandler : BaseRdfHandler
{
protected override bool HandleTripleInternal(Triple t)
{
string predicateUrl = ((BaseUriNode)(t.Predicate)).Uri.AbsoluteUri;
string value = t.Object.ToString();
}
}
This works fine but I want to get the object minus the language. My objects look like "Lincoln"#en. I could obviously write some code to remove the #en bit, but I'd rather use some library code rather than my own that hard-coded strings like #en. To do this I think I need to create a LiteralNode but there doesn't seem to be a way to get from a string which is what I have (my variable value) to a LiteralNode.
How can I extract just the textual value from an object string?
Actually I think I have the answer myself:
if (t.Object.NodeType == NodeType.Literal)
{
var node = (ILiteralNode)t.Object;
}
I apologize for what seems to be an exceedingly simple question, but after 4 hours of searching and beating my head against the wall, I'm doubting my sanity.
I need a string format expression that trims a supplied string argument much like Substring(0,1). Although I've never seen this in code, it just seems like it should be possible.
Here's a very basic example of what I'm trying to do:
string ClassCode = "B608H2014"; // sample value from the user's class schedule
string fRoom = "{0:0,2}";
string fGrade = "{0:2,2}";
string fYear = "{0:5,4}";
string Classroom = String.Format(fRoom, ClassCode); // intended result - "B6"
string Gradelevel = String.Format(fGrade, ClassCode); // intended result - "08"
string Schoolyear = String.Format(fYear, ClassCode); // intended result - "2014"
This is a very basic example, but I'm trying to use the String.Format() so I can store the format pattern(s) in the database for each respective DTO property since the class code layouts are not consistent. I can just pass in the formats from the database along with the required properties and it extracts what I need.
Does this make sense?
I load data from XML into java classes using xstream library. The texts in several tags are very long and take more than one line. Such formatting causes that I have in Java class field text with additional characters like \n\t. Is there any way to load data from XML file without these characters?
Xml tag is declared in two lines. Opening tag is in the first line, then I have very long text, and the closing tag is declared in second line.
You can use regex or the string split method.
String string = "004-034556";
String[] parts = string.split("-");
String part1 = parts[0]; // 004
String part2 = parts[1]; // 034556
Just split your string. In your case it would be
String wantedText = parts[0];
Another solution would be to put your values into a string array, loop the array, match and remove any characters you dont want.
You can see how to match and remove Here
