of
public static <L,R> MutablePair<L,R> of(L left, R right)
Obtains a mutable pair of two objects inferring the generic types.
This factory allows the pair to be created using inference to obtain the generic types.
- Type Parameters:
L
- the left element typeR
- the right element type- Parameters:
left
- the left element, may be nullright
- the right element, may be null- Returns:
- a pair formed from the two parameters, not null
-
