Method Summary

Modifier and Type	Method and Description
static <T> org.hamcrest.Matcher<T>	baseMatcher(java.lang.String descriptionText, java.util.function.Predicate<T> predicate) Creates a matcher that matches when the given predicate returns true.
static <S,T extends S> org.hamcrest.Matcher<S>	typeSafeMatcher(java.lang.Class<T> expectedType, java.lang.String descriptionText, java.util.function.Function<S,java.lang.String> describeActual, java.util.function.Predicate<T> predicate) Creates a matcher that matches when the passed-in object is not null, is an instance of the given type, and the given predicate returns true when that object is passed into it.
static <S,T extends S> org.hamcrest.Matcher<S>	typeSafeMatcher(java.lang.Class<T> expectedType, java.lang.String descriptionText, java.util.function.Predicate<T> predicate) Creates a matcher that matches when the passed-in object is not null, is an instance of the given type, and the given predicate returns true when that object is passed into it.

Method Detail

baseMatcher

public static <T> org.hamcrest.Matcher<T> baseMatcher(java.lang.String descriptionText,
                                                      java.util.function.Predicate<T> predicate)

Creates a matcher that matches when the given predicate returns true.

Parameters:

descriptionText - describes what the matcher tries to match. This is used to explain what happened when a match fails.

predicate - the predicate that the passed-in object must pass (i.e. predicate.apply(object) returns true) to match

typeSafeMatcher

public static <S,T extends S> org.hamcrest.Matcher<S> typeSafeMatcher(java.lang.Class<T> expectedType,
                                                                      java.lang.String descriptionText,
                                                                      java.util.function.Predicate<T> predicate)

Creates a matcher that matches when the passed-in object is not null, is an instance of the given type, and the given predicate returns true when that object is passed into it.

Parameters:

expectedType - the class that the passed-in object must be an instance of to match

descriptionText - describes what the matcher tries to match. This is used to explain what happened when a match fails.

predicate - the predicate that the passed-in object must pass (i.e. predicate.apply(object) returns true) to match

typeSafeMatcher

public static <S,T extends S> org.hamcrest.Matcher<S> typeSafeMatcher(java.lang.Class<T> expectedType,
                                                                      java.lang.String descriptionText,
                                                                      java.util.function.Function<S,java.lang.String> describeActual,
                                                                      java.util.function.Predicate<T> predicate)

Creates a matcher that matches when the passed-in object is not null, is an instance of the given type, and the given predicate returns true when that object is passed into it.

Parameters:

expectedType - the class that the passed-in object must be an instance of to match

descriptionText - describes what the matcher tries to match. This is used to explain what happened when a match fails.

describeActual - a Function which takes as input the "actual" object and produces a String that clearly describes the "actual" object. This is used for producing a human-readable description of the difference between the "expected" and "actual" if the Matcher fails

predicate - the predicate that the passed-in object must pass (i.e. predicate.apply(object) returns true) to match
