JumpInsnNode
Constructs a newJumpInsnNode
.- 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.

getType
public int getType()Description copied from class:AbstractInsnNode
Returns the type of this instruction.- Specified by:
getType
in classAbstractInsnNode
- Returns:
- the type of this instruction, i.e. one the constants defined in this class.
-
accept
Description copied from class:AbstractInsnNode
Makes the given method visitor visit this instruction.- Specified by:
accept
in classAbstractInsnNode
- Parameters:
methodVisitor
- a method visitor.
-
clone
Description copied from class:AbstractInsnNode
Returns a copy of this instruction.- Specified by:
clone
in classAbstractInsnNode
- Parameters:
clonedLabels
- a map from LabelNodes to cloned LabelNodes.- Returns:
- a copy of this instruction. The returned instruction does not belong to any
InsnList
