Class ConstantPool

java.lang.Object
  org.aspectj.apache.bcel.classfile.ConstantPool

All Implemented Interfaces:

Node

public class ConstantPool
extends java.lang.Object
implements Node

This class represents the constant pool, i.e., a table of constants, of a parsed classfile. It may contain null references, due to the JVM specification that skips an entry after an 8-byte constant (double, long) entry.

Method Detail

getSize

public int getSize()

getConstant

public Constant getConstant(int index,
                            byte tag)

getConstant

public Constant getConstant(int index)

copy

public ConstantPool copy()

Returns:

deep copy of this constant pool

getConstantString

public java.lang.String getConstantString(int index,
                                          byte tag)
                                   throws ClassFormatException

Get string from constant pool and bypass the indirection of `ConstantClass' and `ConstantString' objects. I.e. these classes have an index field that points to another entry of the constant pool of type `ConstantUtf8' which contains the real data.

Parameters:

index - Index in constant pool

tag - Tag of expected constant, either ConstantClass or ConstantString

Returns:

Contents of string reference

Throws:

ClassFormatException
