      • getConstantPoolInteger

        public abstract int getConstantPoolInteger​(int index)
        Retrieve the value of a CONSTANT_Integer constant pool item. This method should be overriden by a toolkit-specific subclass.
        Parameters:
        index - the constant pool item to examine
      • getConstantPoolFloat

        public abstract float getConstantPoolFloat​(int index)
        Retrieve the value of a CONSTANT_Float constant pool item. This method should be overriden by a toolkit-specific subclass.
