distinctUntilChanged

public static <T> Observable.OnSubscribeFunc<T> distinctUntilChanged(Observable<? extends T> source,
                                                                     java.util.Comparator<T> equalityComparator)

Returns an Observable that emits all sequentially distinct items emitted by the source.

Parameters:

source - The source Observable to emit the sequentially distinct items for.

equalityComparator - The comparator to use for deciding whether to consider two items as equal or not.

Returns:

A subscription function for creating the target Observable.

distinctUntilChanged

public static <T,U> Observable.OnSubscribeFunc<T> distinctUntilChanged(Observable<? extends T> source,
                                                                       Func1<? super T,? extends U> keySelector,

Returns an Observable that emits all sequentially distinct items emitted by the source.

Parameters:

source - The source Observable to emit the sequentially distinct items for.

keySelector - The function to select the key to use for the equality checks.

equalityComparator - The comparator to use for deciding whether to consider the two item keys as equal or not.

Returns:

A subscription function for creating the target Observable.
