Class DelegatingMatcher<T,U>

java.lang.Object

org.hamcrest.BaseMatcher<T>

org.hamcrest.TypeSafeMatcher<T>

com.atlassian.jira.plugins.ha.testapi.matchers.DelegatingMatcher<T,U>

Type Parameters:

T - The subject type of the new matcher.

U - The subject type of the original delegate matcher.

All Implemented Interfaces:

org.hamcrest.Matcher<T>, org.hamcrest.SelfDescribing

public class DelegatingMatcher<T,U>
extends org.hamcrest.TypeSafeMatcher<T>

Generic helper class to compose custom matchers.

Given a matcher that accepts a type U, constructs a matcher that accepts a type T where T is some type that can access a U.

For example, given that U is a type UpgradeState, and T is a type ClusterNode, we can create a matcher that accepts a ClusterNode by providing 1) a matcher that accepts an UpgradeState; and 2) a function that maps a ClusterNode on to an Upgrade State.
