Jakarta EE 11.0.0 · jakarta.ws.rs.core.Feature · APIdia, the JavaDoc alternative

A feature extension contract. Typically encapsulates a concept or facility that involves configuration of multiple providers (e.g. filters or interceptors) and/or properties.

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	back to summary
public 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 `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`. Parameters context:FeatureContext configurable context in which the feature should be enabled. Returns:boolean `true` if the feature was successfully enabled, `false` otherwise.

public 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 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.

Parameters

context:FeatureContext: configurable context in which the feature should be enabled.

Returns:boolean

true if the feature was successfully enabled, false otherwise.
