Constructor Detail

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
Method Detail

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

getConstantValue

public final ConstantValue getConstantValue()
Returns:
constant value associated with this field (may be null)

toString

public final java.lang.String toString()
Return string representation close to declaration format, `public static final short MAX = 100', e.g..
Overrides:
toString in class java.lang.Object
Returns:
String representation of field, including the signature.

copy

public final Field copy(ConstantPool constant_pool)
Returns:
deep copy of this field
