java.lang.Object
org.hamcrest.BaseMatcher<T>
org.junit.internal.matchers.TypeSafeMatcher<T>
- All Implemented Interfaces:
- org.hamcrest.Matcher<T>, org.hamcrest.SelfDescribing
- Direct Known Subclasses:
- IsCollectionContaining, SubstringMatcher
public abstract class TypeSafeMatcher<T>
- extends org.hamcrest.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.

protected TypeSafeMatcher(java.lang.Class<T> expectedType)
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(java.lang.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
