Class TypeSafeMatcher<T>

java.lang.Object
  org.hamcrest.BaseMatcher<T>
      org.junit.internal.matchers.TypeSafeMatcher<T>

All Implemented Interfaces:

Matcher<T>, SelfDescribing

Direct Known Subclasses:

IsCollectionContaining, SubstringMatcher

public abstract class TypeSafeMatcher<T>
extends BaseMatcher<T>

Convenient base class for Matchers that require a non-null value of a specific type. This simply implements the null check, checks the type and then casts.

Method Detail

matchesSafely

public abstract boolean matchesSafely(T item)

Subclasses should implement this. The item will already have been checked for the specific type and will never be null.

matches

public final boolean matches(Object item)

Method made final to prevent accidental override. If you need to override this, there's no point on extending TypeSafeMatcher. Instead, extend the BaseMatcher.

Parameters:

item - the object against which the matcher is evaluated.

Returns:

true if item matches, otherwise false.
