Field Detail

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 Detail

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 Detail

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 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<LabelNode,LabelNode> 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.
