Operators

operator int()

Returns a non-zero value if the set is non-empty, or 0 if it is empty.

operator+(DimensionSet ds)

Create a new set containing the union of this set with ds. If both input sets are non-empty, they must contain dimensions from the same process array.

operator-(DimensionSet ds)

Create a new set by subtracting ds from this set. If both input sets are non-empty, they must contain dimensions from the same process array.

operator+=(DimensionSet ds)

Replace this set by its union with ds. If both input sets are non-empty, they must contain dimensions from the same process array.

operator-=(DimensionSet ds)

Subtract ds from this set. If both input sets are non-empty, they must contain dimensions from the same process array.

operator+(Dimension d)

Create a new set by adding a dimension to this set. If the set is non-empty before this operation d must be collapsed or a dimension from the same process array as the current elements. Adding a collapsed dimension, or one already in the set, does not change the set.

operator-(Dimension d)

Create a new set by removing d from this set. If the set is non-empty before this operation d must be collapsed or a dimension from the same process array as the current elements. Removing a collapsed dimension, or one not in the set, does not change the set.

operator+=(Dimension d)

Add a dimension to this set. If the set is non-empty before this operation d must be collapsed or a dimension from the same process array as the current elements. Adding a collapsed dimension, or one already in the set, does not change the set.

operator-=(Dimension d)

Remove a dimension from this set. If the set is non-empty before this operation d must be collapsed or a dimension from the same process array as the current elements. Removing a collapsed dimension, or one not in the set, does not change the set.
