Method Detail

canReconnect

public boolean canReconnect(IReconnectionContext context)

Description copied from interface: IReconnection

Can reconnect.

Specified by:

canReconnect in interface IReconnection

Parameters:

context - the context

Returns:

true, if successful

postReconnect

public void postReconnect(IReconnectionContext context)

Description copied from interface: IReconnection

Post reconnnect.

Specified by:

postReconnect in interface IReconnection

Parameters:

context - the context

preReconnect

public void preReconnect(IReconnectionContext context)

Description copied from interface: IReconnection

Pre reconnnect.

Specified by:

preReconnect in interface IReconnection

Parameters:

context - the context

reconnect

public void reconnect(IReconnectionContext context)

Description copied from interface: IReconnection

Reconnnect.

Specified by:

reconnect in interface IReconnection

Parameters:

context - the context

canceledReconnect

public void canceledReconnect(IReconnectionContext context)

Description copied from interface: IReconnection

Will called if the connection reconnect process was canceled after dragging the start or end of the connection. E.g. user pressed ESC, user clicked on an invalid target, focus was lost, ...

Specified by:

canceledReconnect in interface IReconnection

Parameters:

context - the context

Since:

0.9

canExecute

public boolean canExecute(IContext context)

Description copied from interface: IFeature

Decides if the current feature can execute with the given context.

Specified by:

canExecute in interface IFeature

Parameters:

context - this is the general input for this method

Returns:

true if the feature can be executed, false if not

See Also:

IContext

execute

public void execute(IContext context)

Description copied from interface: IFeature

Executes the current feature with the given context.

Specified by:

execute in interface IFeature

Parameters:

context - this is the general input for this method

See Also:

IContext

getName

public java.lang.String getName()

Description copied from interface: IName

Gets the name.

Specified by:

getName in interface IName

Overrides:

getName in class AbstractFeature

Returns:

the name

isAbort

public boolean isAbort()

Description copied from interface: ICustomAbortableUndoRedoFeature

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. In case this method returns true, the operation will be cancelled by the Graphiti framework by throwing an OperationCanceledException that causes am EMF revert of the operation.

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 cancellation indication and check that that flag here.

Specified by:

isAbort in interface ICustomAbortableUndoRedoFeature

Returns:

true in case you want to cancel the current operation, false otherwise.

Since:

0.12

canUndo

public boolean canUndo(IContext context)

Description copied from interface: IFeature

Decides if the current feature can be undone - this is the undo of the execute operation.

Specified by:

canUndo in interface ICustomUndoRedoFeature

Specified by:

canUndo in interface IFeature

Overrides:

canUndo in class AbstractFeature

Parameters:

context - this is the general input for this method

Returns:

true if the feature can be undone, false if not

See Also:

IContext

preUndo

public void preUndo(IContext context)

Description copied from interface: ICustomUndoRedoFeature

This method will be called by the Graphiti framework before the EMF undo is triggered. Customers may revert their non-EMF changes done by the feature here or in ICustomUndoRedoFeature.postUndo(IContext).

Specified by:

preUndo in interface ICustomUndoRedoFeature

Parameters:

context - this is the instance of the IContext object that was in use when executing the feature

Since:

0.12

postUndo

public void postUndo(IContext context)

Description copied from interface: ICustomUndoRedoFeature

This method will be called by the Graphiti framework after the EMF undo is finished. Customers may revert their non-EMF changes done by the feature here or in ICustomUndoRedoFeature.preUndo(IContext).

Specified by:

postUndo in interface ICustomUndoRedoFeature

Parameters:

context - this is the instance of the IContext object that was in use when executing the feature

Since:

0.12

canRedo

public boolean canRedo(IContext context)

Description copied from interface: ICustomUndoRedoFeature

Decides if the processed feature can be re-done. This method is called once by the Graphiti framework just before any redo work is started, e.g. before ICustomUndoRedoFeature.preRedo(IContext).

Note that as soon as any feature reports false here, also all consecutive entries in the command stack are no longer reachable for redo.

Specified by:

canRedo in interface ICustomUndoRedoFeature

Parameters:

context - this is the instance of the IContext object that was in use when executing the feature

Returns:

true if the feature can be re-done, false if not

Since:

0.8

preRedo

public void preRedo(IContext context)

Description copied from interface: ICustomUndoRedoFeature

This method will be called by the Graphiti framework before the EMF undo has triggered. Customers may re-apply their non-EMF changes done by the feature here or in ICustomUndoRedoFeature.postRedo(IContext). (Usually it might be sufficient to delegate to the execution method of the feature.)

Specified by:

preRedo in interface ICustomUndoRedoFeature

Parameters:

context - this is the instance of the IContext object that was in use when executing the feature

Since:

0.12

postRedo

public void postRedo(IContext context)

Description copied from interface: ICustomUndoRedoFeature

This method will be called by the Graphiti framework after the EMF undo has finished. Customers may re-apply their non-EMF changes done by the feature here or in ICustomUndoRedoFeature.preRedo(IContext). (Usually it might be sufficient to delegate to the execution method of the feature.)

Specified by:

postRedo in interface ICustomUndoRedoFeature

Parameters:

context - this is the instance of the IContext object that was in use when executing the feature

Since:

0.12

canStartReconnect

public boolean canStartReconnect(IReconnectionContext context)

Description copied from interface: IReconnection

Can start reconnect.

Specified by:

canStartReconnect in interface IReconnection

Parameters:

context - the context

Returns:

true, if successful

Since:

0.11
