Package com.sun.tools.sjavac.comp

Class SmartWriter

java.lang.Object

java.io.Writer

com.sun.tools.sjavac.comp.SmartWriter

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable

public class SmartWriter
extends Writer

The SmartWriter will cache the written data and when the writer is closed, then it will compare the cached data with the old_content string. If different, then it will write all the new content to the file. If not, the file is not touched.

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.
