Class RuntimeDelegate

Field Detail

• JAXRS_RUNTIME_DELEGATE_PROPERTY

  public static final String JAXRS_RUNTIME_DELEGATE_PROPERTY

  Name of the property identifying the RuntimeDelegate implementation to be returned from getInstance().

  Constant Field Values

Constructor Detail

• RuntimeDelegate

  protected RuntimeDelegate()

  Allows custom implementations to extend the RuntimeDelegate class.

Method Detail

• getInstance

  public static RuntimeDelegate getInstance()

  Obtain a RuntimeDelegate instance. If an instance had not already been created and set via setInstance(RuntimeDelegate), the first invocation will create an instance which will then be cached for future use.

  The algorithm used to locate the RuntimeDelegate subclass to use consists of the following steps:

  • If a resource with the name of META-INF/services/javax.ws.rs.ext.RuntimeDelegate exists, then its first line, if present, is used as the UTF-8 encoded name of the implementation class.
  • If the $java.home/lib/jaxrs.properties file exists and it is readable by the java.util.Properties.load(InputStream) method and it contains an entry whose key is javax.ws.rs.ext.RuntimeDelegate, then the value of that entry is used as the name of the implementation class.
  • If a system property with the name javax.ws.rs.ext.RuntimeDelegate is defined, then its value is used as the name of the implementation class.
  • Finally, a default implementation class name is used.

  Returns:

  an instance of RuntimeDelegate.

• setInstance

  public static void setInstance(RuntimeDelegate rd)

  Set the runtime delegate that will be used by JAX-RS classes. If this method is not called prior to getInstance() then an implementation will be sought as described in getInstance().

  Parameters:

  rd - the runtime delegate instance

  Throws:

  SecurityException - if there is a security manager and the permission ReflectPermission("suppressAccessChecks") has not been granted.

• createUriBuilder

  public abstract UriBuilder createUriBuilder()

  Create a new instance of a UriBuilder.

  Returns:

  new UriBuilder instance.

  UriBuilder

• createResponseBuilder

  public abstract Response.ResponseBuilder createResponseBuilder()

  Create a new instance of a Response.ResponseBuilder.

  Returns:

  new ResponseBuilder instance.

  See Also:

  Response.ResponseBuilder

• createVariantListBuilder

  public abstract Variant.VariantListBuilder createVariantListBuilder()

  Create a new instance of a Variant.VariantListBuilder.

  Returns:

  new VariantListBuilder instance.

  See Also:

  Variant.VariantListBuilder

• createEndpoint

  public abstract <T> T createEndpoint(Application application,
                                       Class<T> endpointType)
                                throws IllegalArgumentException,
                                       UnsupportedOperationException

  Create a configured instance of the supplied endpoint type. How the returned endpoint instance is published is dependent on the type of endpoint.

  Type Parameters:

  T - endpoint type.

  Parameters:

  application - the application configuration.

  endpointType - the type of endpoint instance to be created.

  Returns:

  a configured instance of the requested type.

  Throws:

  IllegalArgumentException - if application is null or the requested endpoint type is not supported.

  UnsupportedOperationException - if the implementation supports no endpoint types.

• createHeaderDelegate

  public abstract <T> RuntimeDelegate.HeaderDelegate<T> createHeaderDelegate(Class<T> type)
                                                                      throws IllegalArgumentException

  Obtain an instance of a RuntimeDelegate.HeaderDelegate for the supplied class. An implementation is required to support the following values for type: CacheControl, Cookie, EntityTag, Link, NewCookie, MediaType and java.util.Date.

  Type Parameters:

  T - header type.

  Parameters:

  type - the class of the header.

  Returns:

  an instance of HeaderDelegate for the supplied type.

  Throws:

  IllegalArgumentException - if type is null.

  See Also:

  RuntimeDelegate.HeaderDelegate

• createLinkBuilder

  public abstract Link.Builder createLinkBuilder()

  Create a new instance of a Link.Builder.

  Returns:

  new Link.Builder instance.
