Class JumpInsnNode

java.lang.Object
org.objectweb.asm.tree.AbstractInsnNode
org.objectweb.asm.tree.JumpInsnNode

public class JumpInsnNode extends AbstractInsnNode
A node that represents a jump instruction. A jump instruction is an instruction that may jump to another instruction.
  • Field Details

    • label

      public LabelNode label
      The operand of this instruction. This operand is a label that designates the instruction to which this instruction may jump.
  • Constructor Details

    • JumpInsnNode

      public JumpInsnNode(int opcode, LabelNode label)
      Constructs a new JumpInsnNode.
      Parameters:
      opcode - the opcode of the type instruction to be constructed. This opcode must be IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.
      label - the operand of the instruction to be constructed. This operand is a label that designates the instruction to which the jump instruction may jump.
  • Method Details

    • setOpcode

      public void setOpcode(int opcode)
      Sets the opcode of this instruction.
      Parameters:
      opcode - the new instruction opcode. This opcode must be IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.
    • 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 methodVisitor)
      Description copied from class: AbstractInsnNode
      Makes the given method visitor visit this instruction.
      Specified by:
      accept in class AbstractInsnNode
      Parameters:
      methodVisitor - a method visitor.
    • clone

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