onFailure

public void onFailure(java.util.function.Consumer<Throwable> consumer)

Description copied from interface: Promise

Callback called when the computation fails

Specified by:

onFailure in interface Promise<T>

Parameters:

consumer - The callback to be activated on error

onComplete

public void onComplete(java.util.function.Consumer<Try<T>> consumer)

Method use 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>

Parameters:

function - The function to applied on success

Returns:

a new promise

filter

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>>
