java.lang.Object
  jef.dna.instructions.impl.InstructionAncestor
      jef.dna.instructions.impl.FALoad

All Implemented Interfaces:

java.lang.Cloneable, Instruction, BytesCountable

public class FALoad
extends InstructionAncestor

This class maps the FALOAD bytecode instruction which loads a float from an array. The first entry on the stack is the index of the float in the array. The second entry on the operand stack is reference to the array.
