javax.tools.JavaFileObject
File abstraction for tools operating on Java™ programming language source and class files.
All methods in this interface might throw a SecurityException if a security exception occurs.
Unless explicitly allowed, all methods in this interface might throw a NullPointerException if given a {@code null} argument. @author Peter von der Ahé @author Jonathan Gibbons @see JavaFileManager @since 1.6
