matches
Description copied from interface:Matcher
Evaluates the matcher for argument item. This method matches against Object, instead of the generic type T. This is because the caller of the Matcher does not know at runtime what the type is (because of type erasure with Java generics). It is down to the implementations to check the correct type.- Parameters:
item
- the object against which the matcher is evaluated.- Returns:
true
if item matches, otherwisefalse
.- See Also:

describeMismatch
Description copied from interface:Matcher
Generate a description of why the matcher has not accepted the item. The description will be part of a larger description of why a matching failed, so it should be concise. This method assumes thatmatches(item)
is false, but will not check this.- Specified by:
describeMismatch
in interfaceMatcher<T>
- Overrides:
describeMismatch
in classBaseMatcher<T>
- Parameters:
item
- The item that the Matcher has rejected.mismatchDescription
- The description to be built or appended to.
