public interface FeatureA feature extension contract. Typically encapsulates a concept or facility that involves configuration of multiple providers (e.g. filters or interceptors) and/or properties.
Featureis a special type of JAX-RS configuration meta-provider. Once a feature is registered, its
configure(FeatureContext)method is invoked during JAX-RS runtime configuration and bootstrapping phase allowing the feature to further configure the runtime context in which it has been registered. From within the invoked
configure(...)method a feature may provide additional runtime configuration for the facility or conceptual domain it represents, such as registering additional contract providers, including nested features and/or specifying domain-specific properties.
Features implementing this interface MAY be annotated with the
@Providerannotation in order to be discovered by the JAX-RS runtime when scanning for resources and providers. Please note that this will only work for server side features. Features for the JAX-RS client must be registered programmatically.

boolean configure(FeatureContext context)A call-back method called when the feature is to be enabled in a given runtime configuration scope. The responsibility of the feature is to properly update the supplied runtime configuration context and return
trueif the feature was successfully enabled or
Note that under some circumstances the feature may decide not to enable itself, which is indicated by returning
false. In such case the configuration context does not add the feature to the collection of enabled features and a subsequent call to
Configuration.isEnabled(Class)method would return
context- configurable context in which the feature should be enabled.
trueif the feature was successfully enabled,
