Get eobject from link [message #1796356]

Hi,

I created an element based edge. I want to change his color if some conditions are met.

So I created a Conditionnal Style however when I use '' view.sourceNode" and "view.targetNode" I can't figure out a way to get an EObject.

I need to get the eobject the nodes are pointing to in order to check his attribute in my condition

Does any one have a clue ?

Hi David,

In an AQL expression, view.sourceNode and view.TargetNode will be the source diagram element and the target diagram element of your current edge.
They are elements of the internal Sirius model. They are also instance of DSemanticDecorator and have a reference "target" which is the link to the semantic model.

Semantic element of the edge:

view.oclAsType(viewpoint::DSemanticDecorator).target

Semantic element of the source:

view.sourceNode.oclAsType(viewpoint::DSemanticDecorator).target

Semantic element of the target:

view.targetNode.oclAsType(viewpoint::DSemanticDecorator).target

Regards,
