Class PredicateImpl<T>

java.lang.Object

org.apache.calcite.runtime.PredicateImpl<T>

Type Parameters:

T - the type of the input to the predicate

All Implemented Interfaces:

Predicate<T>

Deprecated.

Now Calcite is Java 8 and higher, we recommend that you implement Predicate directly.

public abstract class PredicateImpl<T>
extends Object
implements com.google.common.base.Predicate<T>

Abstract implementation of Predicate.

Derived class needs to implement the test(T) method.

Helps with the transition to 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.
