This constructs a command that copies the given collections of objects to the clipboard.

Method Detail

prepare

protected boolean prepare()

Description copied from class: AbstractCommand

Called at most once in AbstractCommand.canExecute() to give the command an opportunity to ready itself for execution. The returned value is stored in AbstractCommand.canExecute(). In other words, you can override this method to initialize and to yield a cached value for the all subsequent calls to canExecute.

Overrides:

prepare in class CopyToClipboardCommand

Returns:

whether the command is executable.
