                  java.lang.String[] interfaces)

Description copied from class: Printer

Class header. See ClassVisitor.visit(int, int, java.lang.String, java.lang.String, java.lang.String, java.lang.String[]).

Specified by:

visit in class Printer

Parameters:

version - the class version. The minor version is stored in the 16 most significant bits, and the major version in the 16 least significant bits.

signature - the signature of this class. May be null if the class is not a generic one, and does not extend or implement generic classes or interfaces.

superName - the internal of name of the super class (see Type.getInternalName()). For interfaces, the super class is Object. May be null, but only for the Object class.

interfaces - the internal names of the class's interfaces (see Type.getInternalName()). May be null.

visitSource

public void visitSource(java.lang.String file,
                        java.lang.String debug)

Description copied from class: Printer

Class source. See ClassVisitor.visitSource(java.lang.String, java.lang.String).

Specified by:

visitSource in class Printer

Parameters:

file - the name of the source file from which the class was compiled. May be null.

debug - additional debug information to compute the correspondence between source and compiled elements of the class. May be null.

                           int access,
                           java.lang.String version)

Description copied from class: Printer

Module. See ClassVisitor.visitModule(java.lang.String, int, java.lang.String).

Overrides:

visitModule in class Printer

Parameters:

visitNestHostExperimental

public void visitNestHostExperimental(java.lang.String nestHost)

Description copied from class: Printer

Experimental, use at your own risk. This method will be renamed when it becomes stable, this will break existing code using it. Nest host class. See ClassVisitor.visitNestHostExperimental(java.lang.String).

Visits the nest host class of the class. A nest is a set of classes of the same package that share access to their private members. One of these classes, called the host, lists the other members of the nest, which in turn should link to the host of their nest. This method must be called only once and only if the visited class is a non-host member of a nest. A class is implicitly its own nest, so it's invalid to call this method with the visited class name as argument.

Overrides:

visitNestHostExperimental in class Printer

Parameters:

nestHost - the internal name of the host class of the nest.

visitOuterClass

name - the name of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.

descriptor - the descriptor of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.

visitNestMemberExperimental

public void visitNestMemberExperimental(java.lang.String nestMember)

Description copied from class: Printer

Experimental, use at your own risk. This method will be renamed when it becomes stable, this will break existing code using it. Nest member name. See ClassVisitor.visitNestMemberExperimental(java.lang.String).

Visits a member of the nest. A nest is a set of classes of the same package that share access to their private members. One of these classes, called the host, lists the other members of the nest, which in turn should link to the host of their nest.
