Constructor Index

 o ConstantValue(ConstantValue)
Initialize from another object.
 o ConstantValue(int, int, int, ConstantPool)

Method Index

 o accept(Visitor)
Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class.
 o copy(ConstantPool)
 o dump(DataOutputStream)
Dump constant value attribute to file stream on binary format.
 o getConstantValueIndex()
 o setConstantValueIndex(int)
 o toString()

Constructors

 o 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.

 o 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

Methods

 o 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
Overrides:
accept in class Attribute
 o dump
 public final void dump(DataOutputStream file) throws IOException
Dump constant value attribute to file stream on binary format.

Parameters:
file - Output file stream
Overrides:
dump in class Attribute
 o getConstantValueIndex
 public final int getConstantValueIndex()
Returns:
Index in constant pool of constant value.
 o setConstantValueIndex
 public final void setConstantValueIndex(int constantvalue_index)
 o toString
 public final String toString() throws InternalError
Returns:
String representation of constant value.
Overrides:
toString in class Attribute
 o copy
 public Attribute copy(ConstantPool constant_pool)
Returns:
deep copy of this attribute
Overrides:
copy in class Attribute
