Examples of javax.tools.FileObject

javax.tools.FileObject
File abstraction for tools. In this context, file means an abstraction of regular files and other sources of data. For example, a file object can be used to represent regular files, memory cache, or data in databases.
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 @since 1.6
