Interface ObservablePatternMatchCollection<M extends IPatternMatch>
-
public interface ObservablePatternMatchCollection<M extends IPatternMatch>Internal interface for building observable pattern match collections. The interface is implemented internally by bothObservablePatternMatchListandObservablePatternMatchSetso theObservablePatternMatchCollectionBuildercan work with both lists and sets.
