getJmxRegistrationStrategy

public static MRulesJmxRegistrationStrategy getJmxRegistrationStrategy()

Returns strategy used to register JMX Beans to monitor rulesets lifecycle steps.

Since:

2.6.0

isJmxAutoRegistrationActivated

public static boolean isJmxAutoRegistrationActivated()

Tells if rulesets should auto register themselves.

Since:

2.6.0

setJmxRegistrationStrategy

public static void setJmxRegistrationStrategy(MRulesJmxRegistrationStrategy newStrategy,
                                              boolean autoRegistration)

Replaces current strategy used to register JMX Beans to monitor rulesets lifecycle steps.
This method should be used with caution, as it can leave already registered MBeans in MBeanServer.
When possible, the global configuration loaded at startup should be preferred.

Parameters:

newStrategy - New registration strategy to use.

autoRegistration - If true, new MBeans will be automatically registered.

Since:

2.6.0

getCacheActivationResolver

public static ICacheActivationResolver getCacheActivationResolver()

Returns cache resolver loaded from global configuration.

Since:

1.8.0

getOptimizerChain

public static IMOptimizerChain getOptimizerChain()

getAddon

public static Class<? extends IAddon> getAddon(String name)

getAddonNames

public static Collection<String> getAddonNames()

getFileName

protected String getFileName()

Overridden to change file names to search for.

Overrides:

getFileName in class ConfigDiscovery

Returns:
