Class ConstantPool

java.lang.Object
org.aspectj.apache.bcel.classfile.ConstantPool
All Implemented Interfaces:
Node
public class ConstantPool extends 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.

  • Constructor Details

    • ConstantPool

      public ConstantPool()

    • ConstantPool

      public ConstantPool(Constant[] constants)

  • Method Details

    • 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 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
