Type Parameters:

T - The type of objects the predicate can evaluate.

All Superinterfaces:

Serializable

All Known Implementing Classes:

Conjunction, Disjunction, FalseIfNull, Predicate.Always, Where

public interface Predicate<T>
extends Serializable

A predicate is a function taking a value of type T, and evaluates it as either true or false.

 ƒ(T) ∈ {true, false}
 

Semantically, a predicate is a specialization of Fn, with the return type set to primitive boolean. Since Java does not allow type parameterization with primitive types, and predicates play such an important role, it has been modeled as its own separate type.
