Class DynamicConfigurationProvider

java.lang.Object

org.mule.runtime.module.extension.internal.runtime.config.LifecycleAwareConfigurationProvider

org.mule.runtime.module.extension.internal.runtime.config.DynamicConfigurationProvider

All Implemented Interfaces:

org.mule.runtime.api.lifecycle.Disposable, org.mule.runtime.api.lifecycle.Initialisable, org.mule.runtime.api.lifecycle.Lifecycle, org.mule.runtime.api.lifecycle.Startable, org.mule.runtime.api.lifecycle.Stoppable, org.mule.runtime.extension.api.runtime.ConfigurationProvider, org.mule.runtime.extension.api.runtime.ExpirableConfigurationProvider

public final class DynamicConfigurationProvider
extends LifecycleAwareConfigurationProvider
implements org.mule.runtime.extension.api.runtime.ExpirableConfigurationProvider

A ConfigurationProvider which continuously evaluates the same ResolverSet and then uses the resulting ResolverSetResult to build an instance of type T

Although each invocation to get(Object) is guaranteed to end up in an invocation to #resolverSet#resolve(Object), the resulting ResolverSetResult might not end up generating a new instance. This is so because ResolverSetResult instances are put in a cache to guarantee that equivalent evaluations of the resolverSet return the same instance.

Since:

4.0.0

Constructor Detail

DynamicConfigurationProvider

public DynamicConfigurationProvider(String name,
                                    org.mule.runtime.api.meta.model.ExtensionModel extensionModel,
                                    org.mule.runtime.api.meta.model.config.ConfigurationModel configurationModel,
                                    ResolverSet resolverSet,
                                    ConnectionProviderValueResolver connectionProviderResolver,
                                    org.mule.runtime.extension.api.runtime.ExpirationPolicy expirationPolicy)

Creates a new instance

Parameters:

name - this provider's name

extensionModel - the model that owns the configurationModel

configurationModel - the model for the returned configurations

resolverSet - the ResolverSet that provides the configuration's parameter values

connectionProviderResolver - a ValueResolver used to obtain a ConnectionProvider

expirationPolicy - the ExpirationPolicy for the unused instances

Method Detail

get

public org.mule.runtime.extension.api.runtime.ConfigurationInstance get(Object event)

Evaluates resolverSet using the given event and returns an instance produced with the result. For equivalent ResolverSetResults it will return the same instance.

Specified by:

get in interface org.mule.runtime.extension.api.runtime.ConfigurationProvider

Parameters:

event - the current event

Returns:

the resolved ConfigurationInstance

registerConfiguration

protected void registerConfiguration(org.mule.runtime.extension.api.runtime.ConfigurationInstance configuration)

Description copied from class: LifecycleAwareConfigurationProvider

Implementations are to invoke this method everytime they create a new ConfigurationInstance so that they're kept track of and the lifecycle can be propagated

Overrides:

registerConfiguration in class LifecycleAwareConfigurationProvider

Parameters:

configuration - a newly created ConfigurationInstance

getExpired

public List<org.mule.runtime.extension.api.runtime.ConfigurationInstance> getExpired()

Specified by:

getExpired in interface org.mule.runtime.extension.api.runtime.ExpirableConfigurationProvider
