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.
