public class UpdateFeatureForPattern
This feature wraps the update functionality of a pattern for calls of the Graphiti framework. Clients should not need to use this class directly.

Constructor Summary | |
---|---|
UpdateFeatureForPattern(IFeatureProvider featureProvider,
IUpdate pattern)
Creates a new UpdateFeatureForPattern . |
Method Summary | |
---|---|
boolean |
canRedo(IContext context)
Decides if the processed feature can be re-done. |
boolean |
canUndo(IContext context)
Decides if the current feature can be undone - this is the undo of the execute operation. |
boolean |
canUpdate(IUpdateContext context)
Checks whether the values of the current pictogram element of the given context can be updated. |
boolean |
isAbort()
The Graphiti framework will call this method after ICustomUndoRedoFeature.preUndo(org.eclipse.graphiti.features.context.IContext) /
ICustomUndoRedoFeature.preRedo(org.eclipse.graphiti.features.context.IContext) have
been called and before the actual undo/redo operation is triggered. |
void |
postRedo(IContext context)
This method will be called by the Graphiti framework after the EMF undo has finished. |
void |
postUndo(IContext context)
This method will be called by the Graphiti framework after the EMF undo is finished. |
void |
preRedo(IContext context)
This method will be called by the Graphiti framework before the EMF undo has triggered. |
void |
preUndo(IContext context)
This method will be called by the Graphiti framework before the EMF undo is triggered. |
void |
redo(IContext context)
Deprecated. use postRedo(IContext) instead |
void |
undo(IContext context)
Deprecated. use postUndo(IContext) instead |
boolean |
update(IUpdateContext context)
Updates the pictogram element. |
IReason |
updateNeeded(IUpdateContext context)
Check whether the values in the pictogram element are up to date, that means whether the graphics algorithm of this pictogram element contain the latest values from the business objects. |

been called and before the actual undo/redo operation is triggered. In
case this method returns true

cancelled by the Graphiti framework by throwing an

that causes am EMF revert of the

Implementing classes might e.g. set a flag in
ICustomUndoRedoFeature.preUndo(org.eclipse.graphiti.features.context.IContext)
/
ICustomUndoRedoFeature.preRedo(org.eclipse.graphiti.features.context.IContext)
as
