Your assumption is correct, but how do I iterate throw the array

 

 

Do you mean you cannot insert NameValue facts into working memory?

 

If this is the case, then you might have to use eval or MVEL dialect. Based upon your model below I assumed you could insert NameValues:-

 

LineItemàgetParameters() returns Parameter[]

Parameter->getNameValueArray() return NameValue[]

Each NameValue has name and value attribute

Yes that’s the simple one, but I can’t send the NameValue, I will send only the LineItem

I forgot to mention, this assumes you want to maintain the relationships. If you're not interested in these but merely want to process all NameValue objects then a simple rule works fine:-

 

rule "don't worry about preserving relationships"

    when

        $n : NameValue ( )

    then

        .....

end

 

Simply assert all NameValue objects.

There are a number of ways...

 

Java dialect [requires LineItem, Parameter and NameValue to be asserted into working memory]

 

rule "a - requires object model change for parent property"

    when

        $l : LineItem( )

        $p : Parameter ( parent == $l )

        $n : NameValue( parent == $p )

    then

        ...

end

 

rule "b"

    when

        $n : NameValue( )

        $p : Parameter ( nameValues contains $n )

        $l : LineItem( parameters contains $p )

    then

        ...

end

 

MVEL dialect

 

rule "c"

    dialect mvel

    when

        $n : my-mvel-syntax-lets-me-down-but-I-know-you-can-traverse-object-graphs-using-it

    then

        ...

end

Hi All,

  I have a object graph like this

LineItem has array of Parameter and each Parameter has array of  NameValue and Namevalue object has name and value.

Now I have LineItem object in working memory, how to test the value of each value of NameValue object.

 

LineItemàgetParameters() returns Parameter[]

Parameter->getNameValueArray() return NameValue[]

Each NameValue has name and value attribute

Any help?
