/**
* Represents a client or server-side configurable context in JAX-RS.
*
* A configurable context can be used to org.testifyproject.testifyprojectfine the JAX-RS org.testifyproject.testifyprojectponents as well as
* additional meta-data that should be used in the scope of the configured context.
* The modification of the context typically involves setting properties or registering
* custom JAX-RS org.testifyproject.testifyprojectponents, such as providers and/or features.
* All modifications of a {@code Configurable} context are reflected in the associated
* {@link Configuration} state which is exposed via {@link #getConfiguration()} method.
*
* A configurable context can be either indirectly associated with a particular JAX-RS org.testifyproject.testifyprojectponent
* (such as application or resource method configurable context passed to a {@link Feature}
* or {@link javax.ws.rs.container.DynamicFeature} meta-providers) or can be directly represented
* by a concrete JAX-RS org.testifyproject.testifyprojectponent implementing the {@code Configurable} interface
* (such as {@link javax.ws.rs.client.Client} or {@link javax.ws.rs.client.WebTarget}).
* As such, the exact scope of a configuration context is typically org.testifyproject.testifyprojecttermined by a use case
* scenario in which the context is accessed.
*
* Setting properties.
*
* New properties can be set using the {@link #property} method. Similarly, updating a value of
* an existing property can be achieved using the same method. Information about the configured set of
* properties is available via the underlying {@code Configuration} object. An existing property
* can be removed by assigning a {@code null} value to the property.
*
* Registering JAX-RS org.testifyproject.testifyprojectponents.
*
* Registered custom JAX-RS org.testifyproject.testifyprojectponent classes and instances are important part of the contextual
* configuration information as these are the main factors that org.testifyproject.testifyprojecttermine the capabilities of
* a configured runtime.
* Implementations SHOULD warn about and ignore registrations that do not conform to the requirements
* of supported JAX-RS org.testifyproject.testifyprojectponents in a given configurable context.
*
*
* In most cases, when registering a JAX-RS org.testifyproject.testifyprojectponent, the simplest form of methods
* ({@link #register(Class)} or {@link #register(Object)}) of the available registration API
* is sufficient.
*
*
* For example:
*
* config.register(HtmlDocumentReader.class);
* config.register(new HtmlDocumentWriter(writerConfig));
*
*
*
* In some situations a JAX-RS org.testifyproject.testifyprojectponent class or instance may implement multiple
* provider contracts recognized by a JAX-RS implementation (e.g. filter, interceptor or entity provider).
* By org.testifyproject.testifyprojectfault, the JAX-RS implementation MUST register the new org.testifyproject.testifyprojectponent class or instance as
* a provider for all the recognized provider contracts implemented by the org.testifyproject.testifyprojectponent class.
*
*
* For example:
*
* @Priority(ENTITY_CODER)
* public class GzipInterceptor
* implements ReaderInterceptor, WriterInterceptor { ... }
*
* ...
*
* // register GzipInterceptor as a ReaderInterceptor
* // as well as a WriterInterceptor
* config.register(GzipInterceptor.class);
*
*
*
* There are however situations when the org.testifyproject.testifyprojectfault registration of a JAX-RS org.testifyproject.testifyprojectponent to all the
* recognized provider contracts is not org.testifyproject.testifyprojectsirable. In such cases users may use other versions of the
* {@code register(...)} method to explicitly specify the collection of the provider contracts
* for which the JAX-RS org.testifyproject.testifyprojectponent should be registered and/or the priority of each registered
* provider contract.
*
*
* For example:
*
* @Priority(USER)
* public class ClientLoggingFilter
* implements ClientRequestFilter, ClientResponseFilter { ... }
*
* @Priority(ENTITY_CODER)
* public class GzipInterceptor
* implements ReaderInterceptor, WriterInterceptor { ... }
*
* ...
*
* // register ClientLoggingFilter as a ClientResponseFilter only
* config.register(ClientLoggingFilter.class, ClientResponseFilter.class);
*
* // override the priority of registered GzipInterceptor
* // and both of it's provider contracts
* config.register(GzipInterceptor.class, 6500);
*
*
*
* As a general rule, for each JAX-RS org.testifyproject.testifyprojectponent class there can be at most one registration
* — class-based or instance-based — configured at any given moment. Implementations
* MUST reject any attempts to configure a new registration for a provider class that has been
* already registered in the given configurable context earlier. Implementations SHOULD also raise
* a warning to inform the user about the rejected org.testifyproject.testifyprojectponent registration.
*
*
* For example:
*
* config.register(GzipInterceptor.class, WriterInterceptor.class);
* config.register(GzipInterceptor.class); // Rejected by runtime.
* config.register(new GzipInterceptor()); // Rejected by runtime.
* config.register(GzipInterceptor.class, 6500); // Rejected by runtime.
*
* config.register(new ClientLoggingFilter());
* config.register(ClientLoggingFilter.class); // rejected by runtime.
* config.register(ClientLoggingFilter.class,
* ClientResponseFilter.class); // Rejected by runtime.
