    - #### setConstantPool

          public final void setConstantPool(ConstantPool constant_pool)

      Parameters:

        `name_index` - Index in constant pool of object's name.

    - #### getSignatureIndex

          public final int getSignatureIndex()

      Returns:
        Index in constant pool of field signature.

    - #### setSignatureIndex

          public final void setSignatureIndex(int signature_index)

        `signature_index` - Index in constant pool of field signature.

    - #### getName

          public final String getName()

      Returns:
        Name of object, i.e., method name or field name

    - #### getSignature

          public final String getSignature()

      Returns:
        String representation of object's type signature (java style)

    - #### copy_

          protected FieldOrMethod copy_(ConstantPool _constant_pool)

      Since:
        6.0

    - #### getGenericSignature

          public final String getGenericSignature()

      Hunts for a signature attribute on the member and returns its contents. So where the 'regular' signature may be (Ljava/util/Vector;)V the signature attribute may in fact say 'Ljava/lang/Vector<Ljava/lang/String>;' Coded for performance - searches for the attribute only when requested - only searches for it once.
      Since:
        6.0
