Hi!

I want to separate the "key" attribute and its "value" in for loop but its printing all keys & values together.can any1 help?

Code:

[for (c: EClass | anEPackage.eAllContents())]
Class Name = [c.name/]
[for (ea: EAnnotation | c.eAllContents())]Annotation Type = [ea.source/]
Key Type = "[ea.details.key/]"
Value Type = "[ea.details.value/]"
[/for]
[/for]

output:
Class Name = Node
Annotation Type = gmf.node
Key Type = "labelborder.colorborder.styleborder.widthfigure"
Value Type = "name0,0,255solid3ellipse"

Reagrds,
fatima

Hi

If you read the metamodel you will see that details is a collection and so details.key is a shortform for details->collect(key).

Hi

You are still very vague, but if you look at the print out that you orially complained about, it was the print out of all the keys in a single collection , and then all the values in another collection. The only purpose of the for loop is to turn the one-dimensional execution of the implicit collect into a two dimensional iteration that does everything N times more often than you want. Scrap the for loop.

hi! from the following code if i want to access any specific key and its corresponding value then how to get it :( :(
(e.g; if key = "width" get the value= "2").

<eAnnotations source="gmf.link">
<details key="label" value="name"/>
<details key="source" value="source"/>
<details key="target" value="target"/>
<details key="style" value="dash"/>
<details key="width" value="2"/>
<details key="color" value="255,255,0"/>
<details key="source.decoration" value="filledsquare"/>
</eAnnotations>

HI

The time has clearly come for you to read the OCL book.

Hi!
Thanks Willink ! i have ordered the book let see when it will reach!
The problem i was facing , i got the idea to solve it :),hence it solved.
Just few small questions :
1* how can i use OR operator in Acceleo e.g, in it [if ea.details.value->at(2) = 'rounded ' || 'rectangle']
2* is there any function in Acceleo which can convert decimal to hex ?
3* can i define use functions and then use them in Acceleo?

Many Thanks!
Regards,
fatima
