public interface Feature
A Feature
is 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 @Provider
annotation 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.

configure(FeatureContext context)
A call-back method called when the feature is to be enabled in a given runtime configuration scope.

boolean configure(FeatureContext context)
true
if the feature was successfully enabled or false
otherwise.
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(Feature)
or Configuration.isEnabled(Class)
method
would return false
.

- configurable context in which the feature should be enabled.true
if the feature was successfully enabled, false
otherwise.
