the opcode of this instruction.

getType

public abstract int getType()

Returns the type of this instruction.

返回：

the type of this instruction, i.e. one the constants defined in this class.

getPrevious

public AbstractInsnNode getPrevious()

Returns the previous instruction in the list to which this instruction belongs, if any.

返回：

the previous instruction in the list to which this instruction belongs, if any. May be null.

getNext

public AbstractInsnNode getNext()
