Specified by:

flatmap in interface Promise<T>

Parameters:

function - The function to applied on success

Returns:

a new promise

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 TApp<M,A,Self extends TApp<M,A,Self>>
