ConstantValue
public ConstantValue(ConstantValue c)
- Initialize from another object. Note that both objects use the same
 references (shallow copy). Use clone() for a physical copy.
 
ConstantValue
public ConstantValue(int name_index,
                     int length,
                     int constantvalue_index,
                     ConstantPool constant_pool)
- Parameters:
- name_index- Name index in constant pool
- length- Content length in bytes
- constantvalue_index- Index in constant pool
- constant_pool- Array of constants
accept
public void accept(Visitor v)
- 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.
