Reynold Xin updated SPARK-9390:
-------------------------------
    Description: 
{code}
interface ArrayData implements SpecializedGetters {
  int numElements();
  int sizeInBytes();
}
{code}


We should also add to SpecializedGetters a method to get array, i.e.

{code}
interface SpecializedGetters {
  ...
  ArrayData getArray(int ordinal);
  ...
}
{code}

  was:
{code}
interface ArrayData implements SpecializedGetters {
  int numElements();
  int sizeInBytes();
}
{code}
