* Abstract implementation of {@link com.hazelcast.com.google.com.hazelcast.com.on.base.Predicate}.
*
* Derived class needs to implement the {@link #test} method.
*
*
Helps with the transition to {@code java.util.function.Predicate},
* which was introduced in JDK 1.8, and is required in Guava 21.0 and higher,
* but still works on JDK 1.7.
*
* @param the type of the input to the predicate
*
* @deprecated Now Calcite is Java 8 and higher, we recommend that you
* implement {@link java.util.function.Predicate} directly.
