Constructor Detail

AbstractValueFactoryProvider

protected AbstractValueFactoryProvider(MultivaluedParameterExtractorProvider mpep,
                                       ServiceLocator injector,
                                       Parameter.Source... compatibleSources)

Initialize the provider.

Parameters:

mpep - MultivaluedParameterExtractorProvider to be used for retrieving extractors that can parameter values from the supplied multivalued parameter map.

Method Detail

getWithoutDefaultValue

protected final MultivaluedParameterExtractor<?> getWithoutDefaultValue(Parameter parameter)

Get a parameter extractor that ignores default value set on the parameter.

Parameters:

parameter - parameter supported by the returned extractor.

Returns:

extractor supporting the parameter. The returned instance ignores any default values set on the parameter.

See Also:

get(org.glassfish.jersey.server.model.Parameter)

get

protected final MultivaluedParameterExtractor<?> get(Parameter parameter)

Get a parameter extractor. Unlike the extractor returned by the getWithoutDefaultValue(org.glassfish.jersey.server.model.Parameter) method, the extractor returned from this method will use the default value set on the parameter, in case the parameter is not found in the supplied multivalued parameter map.

Parameters:

parameter - parameter supported by the returned extractor.

Returns:

extractor supporting the parameter. The returned instance ignores any default values set on the parameter.

createValueFactory

protected abstract Factory<?> createValueFactory(Parameter parameter)

Create a value factory for the parameter. May return null in case the parameter is not supported by the value factory provider.

Parameters:

parameter - parameter requesting the value factory instance.

Returns:

parameter value factory. Returns null if parameter is not supported.

getValueFactory

public final Factory<?> getValueFactory(Parameter parameter)

Get an injected value factory for the parameter. May return null in case the parameter is not supported by the value factory provider.

Specified by:

getValueFactory in interface ValueFactoryProvider

Parameters:

parameter - parameter requesting the value factory instance.

Returns:

injected parameter value factory. Returns null if parameter is not supported.

getPriority

public ValueFactoryProvider.PriorityType getPriority()

Description copied from interface: ValueFactoryProvider

Gets the priority of this provider.

Specified by:

getPriority in interface ValueFactoryProvider

Returns:

the priority of this provider.
