Method Detail

isType

public <T,R> CheckTypeAndValues.AndMembersMatchBuilder<T,R> isType(ActionWithReturn<T,R> a)

Build a Case where we will check if user input matches the Type of the input params on the ActionWithReturn instance supplied If it does, the ActionWithReturn will be executed (applied) to get the result of the Match. isType will attempt to match on the type of the supplied Case class. If it matches the Case class will be 'decomposed' via it's unapply method and the Case will then attempt to match on each of the elements that make up the Case class. If the Case class implements Decomposable, that interface and it's unapply method will be used. Otherwise in Extractors it is possible to register Decomposition Funcitons that will unapply Case classes from other sources (e.g. javaslang, jADT or even Scala). If no Decomposition Function has been registered, reflection will be used to call an unapply method on the Case class if it exists.

Parameters:

a - Action from which the Predicate (by param type) and Function will be extracted to build a Pattern Matching case

Returns:
