Member Function Documentation

abstract void Constant::accept (  Visitor   v )  [pure virtual]
 

Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

Parameters:
v   Visitor object

Reimplemented in ConstantClass, ConstantDouble, ConstantFieldref, ConstantFloat, ConstantInteger, ConstantInterfaceMethodref, ConstantLong, ConstantMethodref, ConstantNameAndType, ConstantString, ConstantUtf8, ConstantClass, ConstantDouble, ConstantFieldref, ConstantFloat, ConstantInteger, ConstantInterfaceMethodref, ConstantLong, ConstantMethodref, ConstantNameAndType, ConstantString, and ConstantUtf8.
