[EuGENia | EOL] delete creation tool [message #483784]

Hello,

I'm trying to delete some creation tools so that they don't appear on
the tools palette.

I've tried experimenting different ways but if I delete any tool then in
gmfmap the tool property in node mapping selects some other tool
available. I want it to map to no tool. I tried deleting from gmftool
anf gmfmap as well. But no luck. Please help me with this.

var rule = ECore!EClass.all.selectOne(o|o.name = 'Rule');
ruleTool = GmfTool!CreationTool.selectOne(t|t.title = 'Rule');

var nodeMapping =
GmfMap!NodeMapping.all.selectOne(nm|nm.domainMetaElement = rule);
--delete nodeMapping.tool;
nodeMapping.tool = ruleTool;
-- even though I do this it does not maps the same tool instead some
other tool is mapped

var r = ECore!EClass.all.selectOne(o|o.name = 'OclExp');
var nodeMapping =
GmfMap!NodeMapping.all.selectOne(nm|nm.domainMetaElement = r);
delete nodeMapping.tool;
--this deletes the tool but in gmfmap some other random tool is selected.

Thanks,
Mihir

Hi Mihir,

You need to unset nodeMapping.tool. An example follows:

------ notool.emf ------

@namespace(uri="notool", prefix="notool")
package notool;

@gmf.diagram
class Model {
val ModelElement[*] contents;
}

@gmf.node(label="name")
abstract class ModelElement {
attr String name;
}

class A extends ModelElement {}

class B extends ModelElement {}

class C extends ModelElement {} // We don't want a tool for this class

class D extends ModelElement {}

class E extends ModelElement {}

------ ECore2GMF.eol ------

var tool = GmfTool!CreationTool.all.selectOne(t|t.title = 'C');
var nodeMapping = GmfMap!NodeMapping.all.selectOne(nm|nm.tool = tool);

delete tool;
nodeMapping.unset('tool');
nodeMapping.tool.println();

operation Any unset(feature:String) {
var sf = self.eClass().eAllStructuralFeatures.
selectOne(sf|sf.name = feature);
self.eUnset(sf);
}

Cheers,
Dimitris

Hello Dimitrios,

when i tried to use your code in ECore2GMF.eol to delete a Tool, i got the following error :

Method 'eClass' not found.

How can that be ?

Hi,

It'd be really hard to guess without additional information. See http://eclipse.org/gmt/epsilon/doc/articles/minimal-examples/

Cheers,

Take this example again :

@namespace(uri="argumentmodel", prefix="argumentmodel")
@gmf(foo="bar")
package argumentmodel;

@gmf.diagram(onefile="false")
class ArgumentModel {
   val Claim[*] claims;
   val Assumption[*] assumptions;
}

@gmf.node(label="name")
class Claim {
   attr String name;
   attr String description;
   @gmf.link(incoming="true")
   val ArgumentStrategy[*] ConnectArg;
}

@gmf.node(label="name",phantom="true")
class ArgumentStrategy {
   attr String description;
   attr String name;
   @gmf.link(incoming="true")
   ref Assumption [*] assumptions;  
}
@gmf.node(label="name")
class Assumption {
   attr String description;
   attr String name;

}

now i tried to add the following in the ECore2GMF.eol:

var tool = GmfTool!CreationTool.all.selectOne(t|t.title = 'assumptions');
var nodeMapping = GmfMap!NodeMapping.all.selectOne(nm|nm.tool = tool);

delete tool;
nodeMapping.unset('tool');
nodeMapping.tool.println();

operation Any unset(feature:String) {
var sf = self.eClass().eAllStructuralFeatures.
selectOne(sf|sf.name = feature);
self.eUnset(sf);
}

What i want to achieve is, that i dont want to see the relation "assumptions" in the connections palette.

and i get the error:

Method 'eClass' not found.

what im doing wrong ?

It's not a NodeMapping, it's a LinkMapping you're looking for. The following should work:

var tool = GmfTool!CreationTool.all.selectOne(t|t.title = 'Assumptions');
var linkMapping = GmfMap!LinkMapping.all.selectOne(nm|nm.tool = tool);

delete tool;
linkMapping.unset('tool');

operation Any unset(feature:String) {
var sf = self.eClass().eAllStructuralFeatures.
selectOne(sf|sf.name = feature);
self.eUnset(sf);
}

Cheers,
Dimitris
