All Implemented Interfaces:

Matcher<T[]>, SelfDescribing

public class IsArray<T>
extends TypeSafeMatcher<T[]>

Matcher for array whose elements satisfy a sequence of matchers. The array size must equal the number of element matchers.

Constructor Summary

IsArray(Matcher<? super T>[] elementMatchers)

Method Summary

static <T> IsArray<T>	array(Matcher<? super T>... elementMatchers) Creates a matcher that matches arrays whose elements are satisfied by the specified matchers.
void	describeMismatchSafely(T[] actual, Description mismatchDescription) Subclasses should override this.
void	describeTo(Description description) Generates a description of the object.
protected java.lang.String	descriptionEnd() Returns the string that ends the description.
protected java.lang.String	descriptionSeparator() Returns the string that separates the elements in the description.
protected java.lang.String	descriptionStart() Returns the string that starts the description.
boolean	matchesSafely(T[] array) Subclasses should implement this.

Method Detail

matchesSafely

public boolean matchesSafely(T[] array)

Description copied from class: TypeSafeMatcher

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

Specified by:

matchesSafely in class TypeSafeMatcher<T[]>

describeMismatchSafely

public void describeMismatchSafely(T[] actual,
                                   Description mismatchDescription)

Description copied from class: TypeSafeMatcher

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

Overrides:

describeMismatchSafely in class TypeSafeMatcher<T[]>

describeTo

public void describeTo(Description description)

Description copied from interface: SelfDescribing

Generates a description of the object. The description may be part of a 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.

descriptionStart

protected java.lang.String descriptionStart()

Returns the string that starts the description. Can be overridden in subclasses to customise how the matcher is described.

descriptionSeparator

protected java.lang.String descriptionSeparator()

Returns the string that separates the elements in the description. Can be overridden in subclasses to customise how the matcher is described.

descriptionEnd

protected java.lang.String descriptionEnd()

Returns the string that ends the description. Can be overridden in subclasses to customise how the matcher is described.

array

public static <T> IsArray<T> array(Matcher<? super T>... elementMatchers)

Creates a matcher that matches arrays whose elements are satisfied by the specified matchers. Matches positively only if the number of matchers specified is equal to the length of the examined array and each matcher[i] is satisfied by array[i].

For example:

assertThat(new Integer[]{1,2,3}, is(array(equalTo(1), equalTo(2), equalTo(3))))

Parameters:

elementMatchers - the matchers that the elements of examined arrays should satisfy
