Class FLoad_1

java.lang.Object
  jef.dna.instructions.impl.InstructionAncestor
      jef.dna.instructions.impl.FLoad_1

All Implemented Interfaces:

java.lang.Cloneable, Instruction, BytesCountable

public class FLoad_1
extends InstructionAncestor

This class maps the FLOAD_1 bytecode instruction which loads a float value from the position 1 of the local variable array of the current frame. The float is then pushed on the top of the operand stack.
