State Machine Behaviour GetComponents does not exist, works fine in monobehaviour.

I am getting an error that says "'Getcomponents' does not exist in the current context" on the below State Machine Behaviour script.

the same syntax works fine in a monobehaviour. i do not now why it does not work in mecanim.

 StateMachineBehaviour
 
 using UnityEngine;
 using System.Collections;
 using HutongGames.PlayMaker;
 
 public class MecPMSendEvent : StateMachineBehaviour {
 
 
     public string TargetFSMName;
     public string EventName;
     private PlayMakerFSM  TargetFSM;
     
     // OnStateEnter is called when a transition starts and the state machine starts to evaluate this state
     override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) {
     
         PlayMakerFSM[]temp= GetComponents<PlayMakerFSM>();
         foreach(PlayMakerFSM fsm in temp){
             if (fsm.FsmName==TargetFSMName){
                 TargetFSM=fsm;
                 break;
     }
 
     
         }
         }
     
 
     
 
     // OnStateExit is called when a transition ends and the state machine finishes evaluating this state
     override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) {
     
             TargetFSM.Fsm.Event(EventName);
 
     
     }
 
     
 }
