  class SemanticsMatcher

---

Wrapper for semantics matcher lambdas that allows to build string explaining to the developer what conditions were being tested.

Summary

Public companion functions
SemanticsMatcher	<T : Any?> expectValue(key: SemanticsPropertyKey<T>, expectedValue: T) Builds a predicate that tests whether the value of the given key is equal to expectedValue.	Cmn
SemanticsMatcher	<T : Any?> keyIsDefined(key: SemanticsPropertyKey<T>) Builds a predicate that tests whether the given key is defined in semantics.	Cmn
SemanticsMatcher	<T : Any?> keyNotDefined(key: SemanticsPropertyKey<T>) Builds a predicate that tests whether the given key is NOT defined in semantics.	Cmn
