Class DynamicConfigurationInstanceProvider<T>

java.lang.Object

org.mule.module.extension.internal.runtime.DynamicConfigurationInstanceProvider<T>

All Implemented Interfaces:

org.mule.extension.runtime.ConfigurationInstanceProvider<T>

public final class DynamicConfigurationInstanceProvider<T>
extends Object
implements org.mule.extension.runtime.ConfigurationInstanceProvider<T>

A ConfigurationInstanceProvider which continuously evaluates the same ResolverSet and then uses the resulting ResolverSetResult to build an instance of a given type.

Although each invocation to get(OperationContext, ConfigurationInstanceRegistrationCallback) is guaranteed to end up in an invocation to #resolverSet#resolve(MuleEvent), 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:

3.7.0

Constructor Detail

DynamicConfigurationInstanceProvider

public DynamicConfigurationInstanceProvider(String name,
                                    org.mule.extension.introspection.Configuration configuration,
                                    ConfigurationObjectBuilder configurationObjectBuilder,
                                    ResolverSet resolverSet)

Creates a new instance

Parameters:

name - the name of the config definition

configuration - the Configuration model

configurationObjectBuilder - the introspection model of the objects this resolver produces

resolverSet - the ResolverSet that's going to be evaluated

Method Detail

get

public T get(org.mule.extension.runtime.OperationContext operationContext,
    org.mule.extension.runtime.ConfigurationInstanceRegistrationCallback registrationCallback)

Evaluates resolverSet using the given event and returns an instance produced with the result. For equivalent ResolverSetResults it will return the same instance, for as long as the expirationInterval and expirationTimeUnit were specified in the constructor

Specified by:

get in interface org.mule.extension.runtime.ConfigurationInstanceProvider<T>

Parameters:

operationContext - a OperationContext

registrationCallback - a ConfigurationInstanceRegistrationCallback to be invoked when a new instance is produced

Returns:

the resolved value

getConfiguration

public org.mule.extension.introspection.Configuration getConfiguration()

Specified by:

getConfiguration in interface org.mule.extension.runtime.ConfigurationInstanceProvider<T>

getName

public String getName()

Specified by:

getName in interface org.mule.extension.runtime.ConfigurationInstanceProvider<T>
