Class ConjunctionMatcher<T>

java.lang.Object

org.hamcrest.BaseMatcher<T>

org.hamcrest.TypeSafeDiagnosingMatcher<T>

org.hobsoft.hamcrest.compose.ConjunctionMatcher<T>

Type Parameters:

T - the type of the object to be matched

All Implemented Interfaces:

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

public final class ConjunctionMatcher<T>
extends org.hamcrest.TypeSafeDiagnosingMatcher<T>

Matcher that composes a list of other matchers using a logical AND.

This matcher differs from CoreMatchers.allOf and CoreMatchers.both in the following ways:

• It does not short circuit. This means that all mismatches are reported, not just the first one.
• It does not describe itself using parenthesis. This produces more readable descriptions.
• It describes each matcher on a separate line
• It supports an optional description to help describe the composition
• It does not repeat the matcher's description when describing a mismatch

Use ComposeMatchers.compose to obtain instances of this class.
