如何从对象元组数组中访问对象的成员

对象类为

class VertexAttributes(val m: Boolean, n: Any){

        val rootParentCustNumber: String = if(n == null) "Was Null" else n.toString
        val firstMsgFlg = m

}

我有此对象类型的RDD:

scala> myGraph.vertices
res92: org.apache.spark.graphx.VertexRDD[VertexAttributes] = VertexRDDImpl[2280] at RDD at VertexRDD.scala:57

在RDD上进行过滤,我得到以下结果:

scala> res92.filter{case(k,m) => k == 964088677}.collect
res94: Array[(org.apache.spark.graphx.VertexId, VertexAttributes)] = Array((964088677,VertexAttributes@2612b83f))

如何访问 VertexAttributes@2612b83f.rootParentCustNumber 在里面 Array((964088677,VertexAttributes@2612b83f))

我试过了 res92.filter{case(k,m) => k == 964088677}.map{case Array(k,m)=> m.rootParentCustNumber}

但我得到以下错误:

<console>:243: error: pattern type is incompatible with expected type;
 found   : Array[T]
 required: (org.apache.spark.graphx.VertexId, VertexAttributes)
    (which expands to)  (Long, VertexAttributes)
       res92.filter{case(k,m) => k == 964088677}.map{case Array(k,m)=> m.rootParentCustNumber}
                                                               ^
