IsCompatibleType

public IsCompatibleType(Class<T> type)

Constructor, best called from typeCompatibleWith(Class).

Parameters:

type - the expected type

Method Details

matchesSafely

public boolean matchesSafely(Class<?> cls)

Description copied from class: TypeSafeMatcher

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

Specified by:

matchesSafely in class TypeSafeMatcher<Class<?>>

Parameters:

cls - the type safe item to match against.

Returns:

boolean true/false depending if item matches matcher.

describeMismatchSafely

public void describeMismatchSafely(Class<?> cls,
 Description mismatchDescription)

Description copied from class: TypeSafeMatcher

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

Overrides:

describeMismatchSafely in class TypeSafeMatcher<Class<?>>

Parameters:

cls - the type safe item to match against.

mismatchDescription - the mismatch description.

describeTo

public void describeTo(Description description)

Description copied from interface: SelfDescribing

Generates a description of the object. The description may be part of a description of a larger object of which this is just a component, so it should be worded appropriately.

Parameters:

description - The description to be built or appended to.

typeCompatibleWith

public static <T> Matcher<Class<?>> typeCompatibleWith(Class<T> baseType)

Creates a matcher of Class that matches when the specified baseType is assignable from the examined class. For example:

assertThat(Integer.class, typeCompatibleWith(Number.class))

Type Parameters:

T - the matcher type.

Parameters:

baseType - the base class to examine classes against

Returns:

The matcher.
