Class SmartFileManager

java.lang.Object

javax.tools.ForwardingJavaFileManager<JavaFileManager>

com.sun.tools.sjavac.comp.SmartFileManager

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable, JavaFileManager, OptionChecker

public class SmartFileManager
extends ForwardingJavaFileManager<JavaFileManager>

Intercepts reads and writes to the file system to gather information about what artifacts are generated. Traps writes to certain files, if the content written is identical to the existing file. Can also blind out the filemanager from seeing certain files in the file system. Necessary to prevent javac from seeing some sources where the source path points.

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.
