Callback(java.util.function.Consumer<java.lang.String> failure) Constructs a Callback with a failure Consumer that occurs when the process it is attached to encounters an error, and whose parameter is the error message.
Callback(java.lang.Runnable success) Constructs a Callback with a success Runnable that occurs when the process it is attached to executes without error.
Callback(java.lang.Runnable success, java.util.function.Consumer<java.lang.String> failure) Constructs a Callback with a success Runnable and a failure Consumer that occurs when the process it is attached to executes without or with error (respectively).

Method Summary

Method Detail

isEmpty

public boolean isEmpty()

Gets whether or not this Callback is "empty" which is more precisely defined as not having a specified success Runnable and/or a failure Consumer.
This is only true if the Callback is constructed with the parameter-less constructor (Callback()) or another constructor that leaves one or both parameters null.

Returns:

true if and only if the

succeed
