takeWhile

public static <T> Observable.OnSubscribeFunc<T> takeWhile(Observable<? extends T> items,
                                                          Func1<? super T,java.lang.Boolean> predicate)

Returns values from an observable sequence as long as a specified condition is true, and then skips the remaining values.

Parameters:

items -

predicate - a function to test each source element for a condition

sequence of observable values from the start as long as the predicate is true

takeWhileWithIndex

public static <T> Observable.OnSubscribeFunc<T> takeWhileWithIndex(Observable<? extends T> items,
                                                                   Func2<? super T,? super java.lang.Integer,java.lang.Boolean> predicate)

Returns values from an observable sequence as long as a specified condition is true, and then skips the remaining values.

Parameters:

items -

predicate - a function to test each element for a condition; the second parameter of the function represents the index of the source element; otherwise, false.

Returns:

sequence of observable values from the start as long as the predicate is true
