Package com.sun.tools.sjavac.comp

Class SmartFileObject

java.lang.Object

com.sun.tools.sjavac.comp.SmartFileObject

All Implemented Interfaces:

FileObject, JavaFileObject

public class SmartFileObject
extends Object
implements JavaFileObject

The SmartFileObject will return an outputstream that cache the written data and compare the new content with the old content on disk. Only if they differ, will the file be updated.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.
