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>)
