Method Detail

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)

Makes the given visitor visit this instruction.

Specified by:

accept in class AbstractInsnNode

Parameters:

mv - a method 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.
