net.md_5.specialsource.AccessMap

public class AccessMap
extends java.lang.Object

Access mapper - for modifying access flags on symbols Supports loading _at.cfg files in the following format:

• comments beginning with '#' extending to end of line
• symbol pattern, space, then access changes

Symbol pattern format:

 foo              class
 foo/bar          field
 foo/bar ()desc   method
 foo/*            fields in class
 foo/* ()desc     methods in class
 *                all classes
 */*       all fields
 */*()     all methods
 **               all classes, fields, and methods
 

Internal ('/') and source ('.') conventions are accepted, and the space preceding the method descriptor is optional. Access change format: visibility (required) + access flags
