Interface AssertFactory<T,​ASSERT extends Assert<?,​?>>

  • Type Parameters:
    T - the type of the input to the factory.
    ASSERT - the type of the resulting Assert.
    All Known Implementing Classes:
    InstanceOfAssertFactory, ObjectAssertFactory
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
    @FunctionalInterface
public interface AssertFactory<T,​ASSERT extends Assert<?,​?>>
    A single method factory interface to create an Assert for a given value. This factory method typically wraps a call to assertThat(t) to produce a concrete assert type ASSERT for the input element of type T.

    This interface is typically used by navigation assertions on iterable types like AbstractIterableAssert when calling assertThat(Iterable<E>, AssertFactory<E, ASSERT>)

      • createAssert

        ASSERT createAssert​(T t)
        Creates the custom Assert object for the given element value. Typically this will just invoke assertThat(t)
        Parameters:
        t - the type to convert to an Assert object
        Returns:
        returns the custom Assert object for the given element value
