Method Details

getContainer

KeyValueContainer getContainer()

Returns the container which accepts loaded entities.

Specified by:

getContainer in interface DataLoader

setContainer

void setContainer(KeyValueContainer container)

Sets the container which accepts loaded entities.

createLoadContext

ValueLoadContext createLoadContext()

Returns ValueLoadContext which is created by the parameters of this loader. The ValueLoadContext can be used with DataManager to load data by the same conditions.

getStoreName

String getStoreName()

Returns data store name.

setStoreName

void setStoreName(String name)

Sets the data store name. By default, the main data store is used.

getLoadDelegate

Function<ValueLoadContext,KeyValueEntity> getLoadDelegate()

Returns a function which will be used to load data instead of standard implementation.

setLoadDelegate

void setLoadDelegate(Function<ValueLoadContext,KeyValueEntity> delegate)

Sets a function which will be used to load data instead of standard implementation.

addPreLoadListener

Subscription addPreLoadListener(Consumer<KeyValueInstanceLoader.PreLoadEvent> listener)

Adds a listener to KeyValueInstanceLoader.PreLoadEvent.

You can also add an event listener declaratively using a controller method annotated with Subscribe:

    @Subscribe(id = "fooDl", target = Target.DATA_LOADER)
     private void onFooDlPreLoad(KeyValueInstanceLoader.PreLoadEvent event) {
         // handle event here
     }
 

Parameters:

listener - listener

Returns:

subscription

addPostLoadListener

Subscription addPostLoadListener(Consumer<KeyValueInstanceLoader.PostLoadEvent> listener)

Adds a listener to KeyValueInstanceLoader.PostLoadEvent.

You can also add an event listener declaratively using a controller method annotated with Subscribe:

    @Subscribe(id = "fooDl", target = Target.DATA_LOADER)
     private void onFooDlPostLoad(KeyValueInstanceLoader.PostLoadEvent event) {
         // handle event here
     }
 

Parameters:

listener - listener

Returns:

subscription
