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.

- Parameters:
name_index
- Name index in constant poollength

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.
-
dump
public final void dump(java.io.DataOutputStream file) throws java.io.IOException
Dump constant value attribute to file stream on binary format.
-
getConstantValueIndex
public final int getConstantValueIndex()
- Returns:
- Index in constant pool of constant value.
-
setConstantValueIndex
public final void setConstantValueIndex(int constantvalue_index)
- Parameters:
constantvalue_index
- the index info the constant pool of this constant value
-
toString
public final java.lang.String toString()
-
copy
public Attribute copy(ConstantPool _constant_pool)
