      public BCField getField()
      Return the owning field.

    • getValueIndex

      public int getValueIndex()

      Return the type of constant this attribute represents, or null if not set.

    • getType

      public Class getType()
      Return the type of constant this attribute represents (String.class, int.class, etc), or null if not set.

    • getTypeBC

      public BCClass getTypeBC()
      Return the bytecode for the type of constant this attribute represents.

    • getValue

      public Object getValue()
