org.eclipse.graphiti.pattern.MoveShapeFeatureForPattern
public class MoveShapeFeatureForPattern
This feature wraps the move shape functionality of a pattern for calls of the Graphiti framework. Clients should not need to use this class directly.

Constructor Summary | |

MoveShapeFeatureForPattern(IFeatureProvider featureProvider,
IPattern pattern)
Creates a new MoveShapeFeatureForPattern . |
Method Summary | |
---|---|
boolean |
canMoveShape(IMoveShapeContext context)
Can move shape. |
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 |
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 |
moveShape(IMoveShapeContext context)
Move shape. |
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 |

ICustomUndoRedoFeature.preRedo(org.eclipse.graphiti.features.context.IContext)
