Method Detail

then

public <I2,R2> void then(AsyncAction<I2,R2> action,
                         com.google.common.base.Function<R,I2> mapper)

Makes the given action to be executed after the main asynchronous action.

Type Parameters:

I2 - An input type

R2 - A result type

Parameters:

action - The chained asynchronous action

mapper - Maps the output of the main asynchronous action to the input of the next action

then

public <R2> void then(AsyncAction<R,R2> action)

Makes the given action to be executed after the main asynchronous action. The output of the main asynchronous action is the input of the given chained asynchronous action.

Type Parameters:

R2 - A result type

Parameters:

action - The chained asynchronous action

then

public void then(java.util.function.Consumer<R> consumer)

Adds a consumer of the output of the main asynchronous action.

Parameters:

consumer - The consumer of the output of the main asynchronous action

onFailure

public void onFailure(java.lang.Throwable caught)

The default on error callback method.

Specified by:

onFailure in interface com.google.gwt.user.client.rpc.AsyncCallback<R>

Parameters:

caught - The exception thrown by the main asynchronous action

onSuccess

public void onSuccess(R result)

The default on success callback method.

Specified by:

onSuccess in interface com.google.gwt.user.client.rpc.AsyncCallback<R>

Parameters:

result - The output of the main asynchronous action
