type of a specially annotated switch expression.
The switch expression is evaluated exactly once in a switch statement.

<h4 id="Expression_switches">Expression switches</h4>

<p>
In an expression switch,
the switch expression is evaluated and
the case expressions, which need not be constants,
are evaluated left-to-right and top-to-bottom; the first one that equals the
switch expression

matches(java.lang.Object item) 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, otherwise false. See Also: BaseMatcher...

Must point to a field of type string, boolean or integer. Types with enum values and strings with formats are allowed. If jsonPath refers to absent field in a resource, the jsonPath evaluates to an empty string. Must not point to metdata fields. Required.",

  // Simple evaluator that attempts to partially evaluate the input value even

  // be evaluated and attempting to partially evaluate those operands. It does
  // so by pushing the operands that need to be required on to the worklist

// similarity to the switch statement, the case statements in a select are
// evaluated in a pseudorandom order if there are multiple channels ready to
// read from when the select is evaluated.  In other words, case statements
// are evaluated in random order, and you can not assume that the case
// statements evaluate in order if multiple channels have events.
