Modifier and Type	Method and Description
static Completable	ifThen(BooleanSupplier condition, CompletableSource then, Completable orElse) Return a Completable that emits the emissions from one specified Completable if a condition evaluates to true, or from another specified Completable otherwise.
static <K> Completable	switchCase(Callable<? extends K> caseSelector, Map<? super K,? extends CompletableSource> mapOfCases, CompletableSource defaultCase) Return a particular one of several possible Completables based on a case selector, or a default Completable if the case selector does not map to a particular one.

Method Detail

switchCase

public static <K> Completable switchCase(Callable<? extends K> caseSelector,
                                         Map<? super K,? extends CompletableSource> mapOfCases,
                                         CompletableSource defaultCase)

Return a particular one of several possible Completables based on a case selector, or a default Completable if the case selector does not map to a particular one.

Type Parameters:

K - the case key type

R - the result value type

Parameters:

caseSelector - the function that produces a case key when an CompletableObserver subscribes

mapOfCases - a map that maps a case key to a Completable

defaultCase - the default Completable if the mapOfCases doesn't contain a value for the key returned by the caseSelector

Returns:

a particular Completable chosen by key from the map of Completables, or the default case if no Completable matches the key

ifThen

public static Completable ifThen(BooleanSupplier condition,
                                 CompletableSource then,
                                 Completable orElse)

Return a Completable that emits the emissions from one specified Completable if a condition evaluates to true, or from another specified Completable otherwise.

Type Parameters:

R - the result value type

Parameters:

condition - the condition that decides which Completable to emit the emissions from

then - the Completable sequence to emit to if condition is true

orElse - the Completable sequence to emit to if condition is false

Returns:

a Completable that mimics either the then or orElse Completables depending on a condition function
