How to compare key value with object in riot?
am trying to compare key value with object in riot pleae suggest
First of all you should be more explicit in your question... What key and value do you want to compare with object? Why do you need riot to do that?
Anyway, you can use lodash API for comparing objects efficiently. If you really need riot you can use if conditional on the HTML element and use a function or inline comparison.
E.g.
<div if={ active: key === object }></div>
You should be more explicit if want appropriate answers

I have an issue rearding the passing of more than one array parameter. I was able to do a "for each" cycle to execute my array parameter "SPPATH", but unfortunately I can pass only one, here is my code:
{"SPPATH":"#{item()}","SPFOLPATH":"#{pipeline().parameters.SPFOLPATH}","updsppath":"#{pipeline().parameters.updsppath}","Storageacct":"#{pipeline().parameters.Storageacct}","sapath":"#{pipeline().parameters.sapath}","saoppath":"#{pipeline().parameters.saoppath}"}
I want to pass "updsppath" also in the array because my output is on different locations, is it possible to do that, if so, how?
thanks in advance
I have reproduced the above and able to iterate multiple arrays inside ForEach.
For this the length of the all arrays should be same.
Use another array for indexes of these.
For Sample I have two array parameters like below.
I have created another array for index like below.
#range(0,length(pipeline().parameters.arr1))
Give this index_array to ForEach.
Create a res array variable in pipeline and inside ForEach, use append variable with the below dynamic content.
#json(concat('{"arr1":"',pipeline().parameters.arr1[item()],'","SPFOLPATH":"',pipeline().parameters.arr2[item()],'"}'))
After ForEach if you look at variable result (for showing here I have assigned to another variable), it will give you the desired JSON.
Result:
You can use this procedure to generate the desired array of objects and pass it to the logic apps as per your requirement.
I am new to Drools, we are trying to create basic validation rules like a NULL check, etc. using the Drools n Scala framework.
I have a source file which has 200 attributes, need to apply NULL-check rule on all these attributes,
is there any easy way to do this? or do I need to create 200 rules for each attribute?
Thanks in advance.
Assuming you have a POJO ("plain old java object", getters/setters and some private variables to hold values) or modern java Records (effectively the same thing), then the answer is no: you need separate rules. For this scenario, the only way to check that field "name" is null is to actually assert against that field like this:
rule "example - name is null"
when
ExampleObject( name == null )
then
System.out.println("Name is null.");
end
However there exist other data structures -- for example, Map and its sibling types -- where you can reference the fields by name. In this case you could theoretically iterate through all of the field names and find the one whose value is empty.
So, for example, Map has a keySet() method which returns a set of fields -- you could iterate through this keyset and for each key check that there is a non-null value present in the map.
rule "example with map"
when
$map: Map()
$keys: Set() from $map.keySet()
$key: String() from $keys
String( this == null ) from $map.get($key)
// or this might work, not sure if the "this" keyword allows this syntax:
// Map( this[$key] == null ) from $map
then
System.out.println($key + " is missing/null");
end
This would require converting your Java object into a Map before passing into the rules.
However I DO NOT RECOMMEND this approach. Maps are extremely un-performant in rules because of how they serialize/deserialize. You will use a ton of unnecessary heap when firing them. If you look at how a HashMap serializes, for example, by peeking at its source code you'll see that it actually contains a bunch of "child" data structures like entryset and keyset and things like that. When using "new", those child structures are only initialized if and when you need them; but when serializing/deserializing, they're created immediately even if you don't need them.
Another solution would be to use Java reflection to get the list of declared field names, and then iterate through those names using reflection to get the value out for that field. In your place I'd do this in Java (reflection is problematic enough without trying to do it in Drools) and then if necessary invoke such a utility function from Drools.
When I do app.getArgument("ARGUMENT_NAME") it returns the reference value for synonym. How do I determine the requested synonym rather than the reference value?
If you look at the JSON, this used to be available in the "result"."parameters"."name.original" field, but that seems to have changed at some point.
Now you can find it in the parameters for any of the contexts. So if you are using JavaScript and have the JSON in a variable named "body" and the argument name in a variable named "name", you can probably evaluate something like
body.result.contexts[0].parameters[`${name}.original`]
to get the value you want.
Lets say i have added a associative array string,string field to the factory through the macro `ovm_field_aa_string_string macro. Is there a way to configure it from command line like we do with simple int fields like follows:
./simv ... +ovm_set_config_int=scope,name,value
is there something like
./simv ... +ovm_set_config_aa_string_string=scope,name,key=val,key2=val2
No, you can only set int's and strings from the command line. I strongly discourge the use of any `uvm_field macros because of their inability to deal with complex times, the the poor simulation performance they impose.
This seems to be already answered by someone else

how to get array of values as plusargs in systemverilog?
After dabbling in C# I'm now keen to use some OOP in Matlab - to date I've done none!
Let's say that I define a class for a data object with a handful of properties...
classdef TestRigData
properties
testTemperature
sampleNumber
testStrainAmplitude
sampleMaterial
rawData
end
methods
% Some constructors and data manipulation methods in here
end
end
...where 'rawData' would be a m-by-n array of actual experimental data, and the other values being doubles or strings to help identify each specific experiment.
If I have an array of TestRigData objects, what would be the best way of finding the indices of objects which meet specific criteria (e.g. testTemperature == 200)? Or getting all the unique values of a property (e.g. all the unique sample numbers in this collection).
If they were arrays of their own, (myNewArray = [3 5 7 22 60 60 5]) it would be easy enough using the find() and unique() functions. Is there a class I can inherit from here which will allow something like that to work on my object array? Or will I have to add my own find() and unique() methods to my class?
You can assign an ID value (a hash value in the general case) to TestRigData objects and store it as a new property. You can then extract all ID values at once to a cell array, e.g {yourarray.id} (or [yourarray.id] if the ID values are scalars), allowing you to apply find and unique with ease.
Adding your own find and unique is definitely possible, of course, but why make life harder? ;)
The suggestion of creating this as a handle class (rather than value class) is something I need to think about more in the future... after having put together some initial code, going back and trying to change classdef TestRigData to classdef TestRigData < handle seems to be causing issues with the constructor.
Bit unclear of how I would go about using a hash value unique to each object... but the syntax of extracting all values to an array is ultimately what got me in the right direction.
Getting a new object array which is the subset of the original big data array conforming to a certain property value is as easy as:
newObjectArray = oldObjectArray([oldObjectArray.testTemperature]==200);
Or for just the indices...
indicesOfInterest = find([oldObjectArray.testTemperature]==200);
Or in the case of non-scalar values, e.g. string property for sample material...
indicesOfInterest = find(strcmpi({oldObjectArray.sampleMaterial},'steel'));
