public final class ConstantValue
extends Attribute

This class is derived from Attribute and represents a constant value, i.e., a default value for initializing a class field. This class is instantiated by the Attribute.readAttribute() method.

constantvalue_index

private int constantvalue_index
Constructor Detail

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

ConstantValue(int name_index,
              int length,
              java.io.DataInputStream file,
              ConstantPool constant_pool)
        throws java.io.IOException
Construct object from file stream.


ConstantValue

public ConstantValue(int name_index,
                     int length,
                     int constantvalue_index,
                     ConstantPool constant_pool)
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.

Specified by:
accept in interface Node
Specified by:
accept in class Attribute

dump

public final void dump(java.io.DataOutputStream file)
                throws java.io.IOException
Dump constant value attribute to file stream on binary format.

Overrides:
dump in class Attribute

getConstantValueIndex

public final int getConstantValueIndex()

setConstantValueIndex

public final void setConstantValueIndex(int constantvalue_index)

toString

public final java.lang.String toString()
Description copied from class: java.lang.Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Overrides:
toString in class Attribute

copy

public Attribute copy(ConstantPool _constant_pool)
Specified by:
copy in class Attribute
