public BooleanFunctionDelegate(Functions.Function1<? super T, Boolean> delegate)

Creates a new BooleanFunctionDelegate that wraps the given delegate function. This implementation will throw a NullPointerException if the delegate's implementation returns null for a given object.

Parameters
delegate:Functions.Function1<? super T, Boolean>

the delegate function. May not be null.

public boolean apply(T input)

Implements com.google.common.base.Predicate.apply.

Doc from com.google.common.base.Predicate.apply.

Returns the result of applying this predicate to input (Java 8+ users, see notes in the class documentation above). This method is generally expected, but not absolutely required, to have the following properties:

  • Its execution does not cause any observable side effects.
  • The computation is consistent with equals; that is, Objects.equal(a, b) implies that predicate.apply(a) == predicate.apply(b)).
