Matcher<Map<? extends K,? extends V>>, SelfDescribing

public final class IsMapWithSize<K,V>
extends FeatureMatcher<Map<? extends K,? extends V>,Integer>

Matches if map size satisfies a nested matcher.

Constructor Summary

IsMapWithSize(Matcher<? super Integer> sizeMatcher)

Method Summary

static <K,V> Matcher<Map<? extends K,? extends V>>	aMapWithSize(int size) Creates a matcher for Maps that matches when the size() method returns a value equal to the specified size.
static <K,V> Matcher<Map<? extends K,? extends V>>	aMapWithSize(Matcher<? super Integer> sizeMatcher) Creates a matcher for Maps that matches when the size() method returns a value that satisfies the specified matcher.
static <K,V> Matcher<Map<? extends K,? extends V>>	anEmptyMap() Creates a matcher for Maps that matches when the size() method returns zero.

Constructor Detail

IsMapWithSize

public IsMapWithSize(Matcher<? super Integer> sizeMatcher)

Method Detail

featureValueOf

protected Integer featureValueOf(Map<? extends K,? extends V> actual)

Specified by:

featureValueOf in class FeatureMatcher<Map<? extends K,? extends V>,Integer>

aMapWithSize

public static <K,V> Matcher<Map<? extends K,? extends V>> aMapWithSize(Matcher<? super Integer> sizeMatcher)

Creates a matcher for Maps that matches when the size() method returns a value that satisfies the specified matcher.

For example:

assertThat(myMap, is(aMapWithSize(equalTo(2))))

Parameters:

sizeMatcher - a matcher for the size of an examined Map

aMapWithSize

public static <K,V> Matcher<Map<? extends K,? extends V>> aMapWithSize(int size)

Creates a matcher for Maps that matches when the size() method returns a value equal to the specified size.

For example:

assertThat(myMap, is(aMapWithSize(2)))

Parameters:

size - the expected size of an examined Map

anEmptyMap

public static <K,V> Matcher<Map<? extends K,? extends V>> anEmptyMap()

Creates a matcher for Maps that matches when the size() method returns zero.

For example:

assertThat(myMap, is(anEmptyMap()))
