Constructor Detail

CompositeOperationHandle

public CompositeOperationHandle(OperationRecorder operationRecorder,
                                CompositeOperation compositeOperation)

Default constructor.

Parameters:

operationRecorder - the change tracker this composite is tracked on

compositeOperation - the composite operation to be handled

Method Detail

isValid

public boolean isValid()

Returns whether the handle is still valid.

false if the composite operation is already completed or aborted.

abort

public void abort()
           throws InvalidHandleException

Throws:

InvalidHandleException - if the handle is invalid

end

public void end(String name,
                String description,

Completes a composite operation.

Parameters:

name - the name for the operation

description - the description of the operation

modelElementId - the id of the model element that is most important for the operation

Throws:

InvalidHandleException - if the handle is invalid

end

public void end(SemanticCompositeOperation semanticCompositeOperation)
         throws InvalidHandleException

Completes a the given semantic composite operation.

Parameters:

semanticCompositeOperation - a semanticCompositeOperation that was executed and represents the composite

Throws:

InvalidHandleException - if the handle is invalid
