org.springframework.roo.process.manager.MutableFile

Represents a handle to a file (not a directory) that can be legally modified.

It is critical that classes using {@link MutableFile} close any streamsacquired from the file before further {@link UndoManager} operations. Failureto do so many compromise the ability of {@link UndoManager} to operatecorrectly.

Implementations must guarantee that the file physically exists and is indeed a file. Specifically, {@link MutableFile} implementations should not existfor directories or non-existent files. @author Ben Alex @since 1.0
