Cardinality with the ambiguity removed.

<p>"No session matched" and "several sessions matched" are different bugs in a caller's code, so they get different exceptions. findFirst stays on java.util.stream.Stream where it already belongs; only the strict shapes need helpers.

Members

• MultipleMatchesException class Several things matched where the caller required at most one.
• NoMatchException class Nothing matched where the caller required something.
• exactlyOne method The single match, or a failure naming which way the count was wrong.
• oneOrEmpty method The single match if there is one, empty if there is none — but still a failure for several.
