Method Detail

apply

public <R> R apply(java.util.function.Function<HK<Promise,T,Promise<T>>,R> f)

Specified by:

apply in interface HK<Promise,T,Promise<T>>

map

public final <R> Promise<R> map(FunctionWithError<? super T,? 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 applied on success which can raise an error

Returns:

a new promise

flatmap

public final <R> Promise<R> flatmap(java.util.function.Function<? super T,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 applied on success

Returns:

a new promise

filter

public HK<Promise,T,Promise<T>> filter(java.util.function.Predicate<? super T> 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<T> self()

Specified by:

self in interface HK<Promise,T,Promise<T>>
