Method Details

map

public final <R> Promise<R> map(FunctionWithError<? super Unit,? extends R> function)

Description copied from interface: Promise

Method used to map a function. This mapping is done when the operation is a success. The result of this mapping is a new promise component.

Specified by:

map in interface Promise<T>

Type Parameters:

R - the promised value type

Parameters:

function - The function to apply on success which can raise an error

Returns:

a new promise

biMap

public final <R> Promise<R> biMap(FunctionWithError<? super Unit,? extends R> onSuccess,
 FunctionWithError<? super Throwable,? extends R> onError)

Description copied from interface: Promise

Method used to map a function on success and another one on error. The result of this mapping is a new promise component.

Specified by:

biMap in interface Promise<T>

Type Parameters:

R - the promised value type

Parameters:

onSuccess - The function to apply on success which can raise an error

onError - The function to apply on error which can also raise an error

Returns:

a new promise

flatmap

public final <R> Promise<R> flatmap(java.util.function.Function<? super Unit,Promise<R>> function)

Description copied from interface: Promise

Method used to flatmap a function. This mapping is done when the operation is a success. The result of this mapping is a new promise component.

Specified by:

flatmap in interface Promise<T>

Type Parameters:

R - the promised value type

Parameters:

function - The function to apply on success

Returns:

a new promise

filter

public final Promise<Unit> filter(java.util.function.Predicate<? super Unit> predicate)

Description copied from interface: Filter

Method called when the current data must be filtered using a given predicate.

Specified by:

filter in interface Filter<Promise,T,Promise<T>>

Parameters:

predicate - The filter

Returns:

a filtered data

self

public final Promise<Unit> self()
