Package com.oracle.coherence.mp.config

Class CoherenceConfigSource

java.lang.Object

com.oracle.coherence.mp.config.CoherenceConfigSource

All Implemented Interfaces:

EventDispatcherAwareInterceptor<CacheLifecycleEvent>, EventInterceptor<CacheLifecycleEvent>, org.eclipse.microprofile.config.spi.ConfigSource

@ApplicationScoped
public class CoherenceConfigSource
extends Object
implements org.eclipse.microprofile.config.spi.ConfigSource, EventDispatcherAwareInterceptor<CacheLifecycleEvent>

An implementation of ConfigSource that reads configuration properties from a Coherence map.

Be default, this config source has the ordinal of 500. That implies that any config properties in it will override properties with the same name from standard MP config sources (files, environment variables and Java system properties). The ordinal value can be changed via coherence.config.ordinal config property.

This config source is also mutable. It can be injected into any application class by the CDI container, and the values can be modified by calling invalid input: '{@link /*missing*/}'

Since:

20.06

introduceEventDispatcher

public void introduceEventDispatcher(String sIdentifier,
 EventDispatcher dispatcher)

Description copied from interface: EventDispatcherAwareInterceptor

Introduce and possibly bind this EventInterceptor to the specified EventDispatcher.

Specified by:

introduceEventDispatcher in interface EventDispatcherAwareInterceptor<CacheLifecycleEvent>

Parameters:

sIdentifier - the unique name identifying this interceptor

dispatcher - the dispatcher being introduced

onEvent

public void onEvent(CacheLifecycleEvent event)

Description copied from interface: EventInterceptor

Perform necessary processing of the specified Event.

Specified by:

onEvent in interface EventInterceptor<CacheLifecycleEvent>

Parameters:

event - the Event to be processed

• Event.nextInterceptor()

getConfigMap

public NamedMap<String,String> getConfigMap()

For testing.

Returns:

internal config map
