Constructor Detail

SetValueCommand

public SetValueCommand(SetRequest request)
Constructs a new command to set the value of a feature of a model element.

Parameters:
request - the set value request
Method Detail

doExecuteWithResult

protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
                                            IAdaptable info)
                                     throws ExecutionException
Description copied from class: AbstractTransactionalCommand
Implemented by subclasses to perform the model changes. These changes are applied by manipulation of the EMF metamodel's API, not by executing commands on the editing domain's command stack.

Specified by:
doExecuteWithResult in class AbstractTransactionalCommand
Parameters:
monitor - the progress monitor provided by the operation history
info - the adaptable provided by the operation history
Returns:
the result of the execution
Throws:
ExecutionException - if, for some reason, I fail to complete the operation

canExecute

public boolean canExecute()
Checks that the feature is a modifiable feature of the element whose value will be set by this command. Also checks that the new value is of the correct type for the feature.

Specified by:
canExecute in interface IUndoableOperation
Overrides:
canExecute in class EditElementCommand
