Base class for an array with an optional mask.
Internal
This class is the base class of the templated class MArray. It contains the functions that are not template dependent.
MArray is developed to make it easier to handle arrays with an optional mask. The array is always present, but the mask is optional. MArrayMath contains functions to operate on such arrays.
Similar to numpy.masked_array and the MeasurementSet FLAG definition, a mask value True means that the corresponding value is masked off, thus is not taken into account in reduction functions like sum
. on a masked array. In operations like addition, masked off values are processed because testing the mask value is more expensive than an addition (even if the value is a NaN). For an operation with multiple operands, the mask of the result is the OR of the operand masks.
MArray can be null meaning that the array is a null value. It can be used to indicate that a table cell does not contain an array. A null MArray has an empty array and mask. Operations where an operand is a null MArray, result in a null MArray.
