Package org.apache.calcite.runtime

Class PredicateImpl<T>

  • Type Parameters:
    T - the type of the input to the predicate
    All Implemented Interfaces:
    com.google.common.base.Predicate<T>
    public abstract class PredicateImpl<T>
extends java.lang.Object
implements com.google.common.base.Predicate<T>
    Deprecated.
    Now Calcite is Java 8 and higher, we recommend that you implement Predicate directly.
    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.
