Method Detail
-
activate
public void activate()
Adds this EditPart as an AnchorListener on activation.- Specified by:
activate
in interfaceorg.eclipse.gef.EditPart
- Overrides:
activate
in classorg.eclipse.gef.editparts.AbstractGraphicalEditPart
-
createEditPolicies
protected void createEditPolicies()
- Specified by:
createEditPolicies
in classorg.eclipse.gef.editparts.AbstractEditPart
-
createFigure
protected org.eclipse.draw2d.IFigure createFigure()
- Overrides:

-
deactivate
public void deactivate()
Removes this EditPart as an AnchorListener on deactivation.- Specified by:
deactivate
in interfaceorg.eclipse.gef.EditPart
- Overrides:

in classorg.eclipse.gef.editparts.AbstractGraphicalEditPart
-
getConfigurationProvider
public IConfigurationProviderInternal getConfigurationProvider()
Gets the configuration provider.- Specified by:
getConfigurationProvider
in interfaceIConfigurationProviderHolder
- Returns:
- The IConfigurationProviderInternal of this EditPart
-
getConnection
protected Connection getConnection()
Gets the connection.- Returns:
- the connection
-
getPictogramElement
public PictogramElement getPictogramElement()
Description copied from class:GraphitiConnectionEditPart
Returns thePictogramElement
(the model object) that thisEditPart
represents.- Specified by:
getPictogramElement
in interfaceIPictogramElementEditPart
- Specified by:
getPictogramElement
in classGraphitiConnectionEditPart
- Returns:
- the
PictogramElement
-
refreshVisuals
protected void refreshVisuals()
This method is called, whenever the data of the underlying ModelObject changes. It must update the figures to display the changed data. Sub-classes will nearly always overwrite this method.By default this method takes care to update the labels of the attributes (if existing) and to update the arrows at the connection-endpoints, so sub-classes should call super.refreshVisuals().
- Overrides:
refreshVisuals
in classorg.eclipse.gef.editparts.AbstractEditPart
- See Also:
AbstractEditPart.refreshVisuals()
-
getModelChildren
public java.util.List<PictogramElement> getModelChildren()

in classorg.eclipse.gef.editparts.AbstractGraphicalEditPart
- Returns:
- the model source connections
-
getModelTargetConnections
