Subtracts subtrahend from minuend and stores the result in dest.
Note that this means subtraction as in sets, not as in mathematics.
| dest |
the destination value for the result if the subtraction is not empty. May be null, in which case the resulting set will not be computed, which can give a fair speedup. |
| minuend |
the value to subtract from |
| subtrahend |
the value to subtract |
|
true if the subtraction is not empty |
