Method GetArrayContainingComponent

Common/DataModel/vtkFieldData.cxx:578–596

------------------------------------------------------------------------------ Return the array containing the ith component of the field. The return value is an integer number n 0<=n NumberOfArrays. Also, an integer value is returned indicating the component in the array is returned. Method returns -1 if specified component is not in field.

// returned indicating the component in the array is returned. Method returns
// -1 if specified component is not in field.
