Class DefaultODataProducerProvider

java.lang.Object
  org.odata4j.producer.resources.DefaultODataProducerProvider

All Implemented Interfaces:

ContextResolver<ODataProducer>

Direct Known Subclasses:

ODataProducerProvider

@Provider
public class DefaultODataProducerProvider
extends Object
implements ContextResolver<ODataProducer>

Default OData producer provider.

OData producer instances can either be set statically (method setInstance) or created by a factory (ODataProducerFactory) specified by the corresponding system property (constant FACTORY_PROPNAME).

To introduce an additional container-specific setting, it is required to extend this class and override method createInstanceFromFactoryInContainerSpecificSetting. Furthermore a subclass of AbstractODataApplication has to be created to make the new provider available to the JAX-RS runtime.

Field Summary

static String

FACTORY_PROPNAME Constant used as system property name.

Constructor Summary

Specified by:

getContext in interface ContextResolver<ODataProducer>

log

protected final void log(String msg)

Helper method to log an INFO message.

Parameters:

msg - the log message

protected final ODataProducer newProducerFromFactory(String factoryTypeName,
                                                     Properties props)

Helper method to create an OData producer instance from a given producer factory (ODataProducerFactory).

Parameters:

factoryTypeName - the factory's type name (fully qualified)
