+--jellyj.classfile.javaclass.ConstantValue
- 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
public ConstantValue()
- Empty constructor, all attributes have to be defined via `setXXX'
methods. Use at your own risk.
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, DataInputStream file, ConstantPool constant_pool)
throws java.io.IOException
- Construct object from file stream.
- Parameters:
- name_index - Name index in constant pool
- length - Content length in bytes
- file - Input stream
- constant_pool - Array of constants
- throw IOException
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
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
dump
public final void dump(DataOutputStream file)
throws java.io.IOException
- Dump constant value attribute to file stream on binary format.
- Parameters:
- file - Output file stream
- throw IOException
getConstantPool
public final ConstantPool getConstantPool()
- Returns: Constant pool used by this object.

getConstantValueIndex
public final int getConstantValueIndex()
- Returns: Index in constant pool of constant value.
setConstantPool
public final void setConstantPool(ConstantPool constant_pool)
- Parameters:
- constant_pool - Constant pool to be used for this object.
- See Also:
- ConstantPool
setConstantValueIndex
public final void setConstantValueIndex(int constantvalue_index)
- Parameters:
- constantvalue_index.
toString
public final String toString()
throws java.lang.InternalError
- Returns: String representation of constant value.
