Interface ObservationReporter

public interface ObservationReporter

A ResourceProvider must use an observation reporter to report changes to resources. The resource provider gets an instance of this reporter through the ProviderContext.

Since:

1.0.0 (Sling API Bundle 2.11.0)

Method Summary

Modifier and Type	Method and Description
java.util.List<ObserverConfiguration>	getObserverConfigurations() Get the list of observer configurations affecting the provider this reporter is bound to.
void	reportChanges(java.lang.Iterable<ResourceChange> changes, boolean distribute) A resource provider can inform about a list of changes.

Method Detail

getObserverConfigurations

java.util.List<ObserverConfiguration> getObserverConfigurations()

Get the list of observer configurations affecting the provider this reporter is bound to.

Returns:

A list of observer configurations, the list might be empty.

reportChanges

void reportChanges(java.lang.Iterable<ResourceChange> changes,
                   boolean distribute)

A resource provider can inform about a list of changes. If the resource provider is not able to report external events on other instances, it should set the distribute flag. In this case the resource resolver implementation will distribute the events to all other instances. Due to performance reasons, the observation reporter might not verify if the reported change matches the observer configurations.

Parameters:

changes - The list of changes.

distribute - Whether the changes should be distributed to other instances.
