Hello,

currently I convert XMI files, to be processed in Eclipse. Following extract of the XMI:

<ownedAttribute xmi:type="uml:Property" name="testAttr2" xmi:id="BOUML_0x27617_1" visibility="public">
	<defaultValue xmi:type="uml:LiteralString" xmi:id="BOUML_VALUE_0x27617_1" value="56"/>
</ownedAttribute>

evaluates to the following tree structure of the LiteralString:

obj (LiteralStringImpl)
	|
	+- ...
	+- eContainer (PropertyImpl)
		|
		+- ...
		+- defaultValue (LiteralStringImpl)
			|
			+- ...
			+- value ("56")

But with what method of "obj" I get the value "56" of the defaultValue?

Thanks in advance and best regards
Tom

Tom,

This sounds like a UML2 question that's best asked on the UML2
newsgroup, which I've added to the "to" list of the reply, so no need to
repost. I bet if you used the debugger (your best friend) to look at
the instance you'd know which field stores the value and then you could
look at the source code to see which method returns that field...

Hello Ed,

thanks for your reply and adding the topic to the UML2 newsgroup!

That is what have done, but I wasn't really succesful - that's why I've posted the question Smile
