  • Field Details

    • var

      public int var
      The operand of this instruction. This operand is the index of a local variable.

  • Constructor Details

    • VarInsnNode

      public VarInsnNode(int opcode, int var)
      Constructs a new VarInsnNode.
      Parameters:
      opcode - the opcode of the local variable instruction to be constructed. This opcode must be ILOAD, LLOAD, FLOAD, DLOAD, ALOAD, ISTORE, LSTORE, FSTORE, DSTORE, ASTORE or RET.
      var - the operand of the instruction to be constructed. This operand is the index of a local variable.

  • Method Details

    • setOpcode

      public void setOpcode(int opcode)
      Sets the opcode of this instruction.
      Parameters:
      opcode - the new instruction opcode. This opcode must be ILOAD, LLOAD, FLOAD, DLOAD, ALOAD, ISTORE, LSTORE, FSTORE, DSTORE, ASTORE or RET.

    • getType

      public int getType()
      Description copied from class: AbstractInsnNode
      Returns the type of this instruction.
      Specified by:
      getType in class AbstractInsnNode
      Returns:
      the type of this instruction, i.e. one the constants defined in this class.

    • accept

      public void accept(MethodVisitor mv)
      Description copied from class: AbstractInsnNode
      Makes the given code visitor visit this instruction.
      Specified by:
      accept in class AbstractInsnNode
      Parameters:
      mv - a code visitor.

    • clone

      public AbstractInsnNode clone(Map labels)
      Description copied from class: AbstractInsnNode
      Returns a copy of this instruction.
      Specified by:
      clone in class AbstractInsnNode
      Parameters:
      labels - a map from LabelNodes to cloned LabelNodes.
      Returns:
      a copy of this instruction. The returned instruction does not belong to any InsnList.
