All Implemented Interfaces:

ICustomUndoableFeature, IFeature, IFeatureProviderHolder, IReconnectionFeature, IReconnection, IDescription, IName

public class ReconnectionFeatureForPattern
extends AbstractFeature
implements IReconnectionFeature, ICustomUndoableFeature

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

private static String	NAME

Constructor Summary

ReconnectionFeatureForPattern(IFeatureProvider fp, IReconnection pattern)
Creates a new ReconnectionFeatureForPattern.

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:

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

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

IContext

getName

public String getName()

Description copied from interface: IName

Gets the name.

Specified by:

getName in interface IName

Overrides:

getName in class AbstractFeature

Returns:

the name

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 ICustomUndoableFeature

Specified by:

canUndo in interface IFeature

Overrides:

canUndo in class AbstractFeature

Parameters:

IContext

undo

public void undo(IContext context)

Description copied from interface: ICustomUndoableFeature

This method will be called to actually do the work needed for undo. Customers may revert their non-EMF changes done by the feature here.

Specified by:

undo in interface ICustomUndoableFeature

Parameters:

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

Since:

0.8

canRedo

public boolean canRedo(IContext context)

Description copied from interface: ICustomUndoableFeature

Decides if the processed feature can be re-done.

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 ICustomUndoableFeature

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

redo

public void redo(IContext context)

Description copied from interface: ICustomUndoableFeature

This method will be called to actually do the work needed for redo. Customers may re-apply their non-EMF changes done by the feature here. (Usually it might be sufficient to delegate to the execution method of the feature.)

Specified by:

redo in interface ICustomUndoableFeature

Parameters:

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

Since:

0.8
