Constructor Detail

IsArrayWithSize

public IsArrayWithSize(Matcher<? super java.lang.Integer> sizeMatcher)

Method Detail

featureValueOf

protected java.lang.Integer featureValueOf(E[] actual)

Description copied from class: FeatureMatcher

Implement this to extract the interesting feature.

Specified by:

featureValueOf in class FeatureMatcher<E[],java.lang.Integer>

Parameters:

actual - the target object

Returns:

the feature to be matched

arrayWithSize

public static <E> Matcher<E[]> arrayWithSize(Matcher<? super java.lang.Integer> sizeMatcher)

Does array size satisfy a given matcher?

arrayWithSize

public static <E> Matcher<E[]> arrayWithSize(int size)

This is a shortcut to the frequently used arrayWithSize(equalTo(x)). For example, assertThat(arrayWithSize(equal_to(x))) vs. assertThat(arrayWithSize(x))

emptyArray

public static <E> Matcher<E[]> emptyArray()

Matches an empty array.
