public interface Predicate<T>
RegexPredicate
might implement Predicate<String>
, and return
true
for any string that matches its given regular expression.
Implementations which may cause side effects upon evaluation are strongly encouraged to state this fact clearly in their API documentation.

Predicate
.
This method can return true
only if the specified object is
also a Predicate
and, for every input object input
, it
returns exactly the same value. Thus, predicate1.equals(predicate2)
implies that either predicate1.apply(input)
and
predicate2.apply(input)
are both true
or both
false
.
Note that it is always safe not to override
Object.equals(java.lang.Object)
