Method Detail

tag

public int tag()
Return the tag for this constant

Specified by:
tag in class ConstBasic

className

public ConstUtf8 className()
Return the class name


descriptor

public java.lang.String descriptor()
Return the descriptor string for the constant type.

Specified by:
descriptor in class ConstValue

asString

public java.lang.String asString()
Return the class name in simple string form


toString

public java.lang.String toString()
A printable representation


changeClass

public void changeClass(ConstUtf8 newName)
Change the class reference (not to be done lightly)


isEqual

public boolean isEqual(java.util.Stack msg,
                       java.lang.Object obj)
Compares this instance with another for structural equality.

Overrides:
isEqual in class ConstBasic

formatData

void formatData(java.io.DataOutputStream b)
          throws java.io.IOException
Description copied from class: ConstBasic
Write this Constant pool entry to the output stream

Specified by:
formatData in class ConstBasic
Throws:
java.io.IOException

read

static ConstClass read(java.io.DataInputStream input)
                throws java.io.IOException
Throws:
java.io.IOException

resolve

void resolve(ConstantPool p)
Description copied from class: ConstBasic
Resolve integer index references to the actual constant pool entries that they represent. This is used during class file reading because a constant pool entry could have a forward reference to a higher numbered constant.

Specified by:
resolve in class ConstBasic
