Field
public Field(Field c)
- Initialize from another object. Note that both objects use the same
references (shallow copy). Use clone() for a physical copy.
Field
public Field(int access_flags,
int name_index,
int signature_index,
Attribute[] attributes,
ConstantPool constant_pool)
- Parameters:
access_flags
- Access rights of field
name_index
- Points to field name in constant pool
signature_index
- Points to encoded signature
attributes
- Collection of attributes
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.
- Parameters:
v
- Visitor object
