Interface UnaryEquator<T>
- Type Parameters:
T
- Type of compared entity
- All Superinterfaces:
BiPredicate<T,
T>
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
Checks equality between 2 entities of same type

and
Returns a composed equator that represents a short-circuiting logical AND of this equator and another. When evaluating the composed equator, if this equator isfalse
, then theother
equator is not evaluated.- Parameters:
other
- The other (nevernull
equator- Returns:
- The compound equator
