Interface ClientRequestContext

public interface ClientRequestContext
Client request filter context. A mutable class that provides request-specific information for the filter, such as request URI, message headers, message entity or request-scoped properties. The exposed setters allow modification of the exposed request-specific information.

  • Method Details

    • getProperty

      Object getProperty​(String name)
      Returns the property with the given name registered in the current request/response exchange context, or null if there is no property by that name.

      A property allows a JAX-RS filters and interceptors to exchange additional custom information not already provided by this interface.

      A list of supported properties can be retrieved using getPropertyNames(). Custom property names should follow the same convention as package names.

      Parameters:
      name - a String specifying the name of the property.
      Returns:
      an Object containing the value of the property, or null if no property exists matching the given name.
      See Also:
      getPropertyNames()

    • getPropertyNames

      Collection<String> getPropertyNames()
      Returns an immutable collection containing the property names available within the context of the current request/response exchange context.

      Use the getProperty(java.lang.String) method with a property name to get the value of a property.

      Returns:
      an immutable collection of property names.
      See Also:
      getProperty(java.lang.String)

    • setProperty

      void setProperty​(String name, Object object)
      Binds an object to a given property name in the current request/response exchange context. If the name specified is already used for a property, this method will replace the value of the property with the new value.

      A property allows a JAX-RS filters and interceptors to exchange additional custom information not already provided by this interface.

      A list of supported properties can be retrieved using getPropertyNames(). Custom property names should follow the same convention as package names.

      If a null value is passed, the effect is the same as calling the removeProperty(String) method.

      Parameters:
      name - a String specifying the name of the property.
      object - an Object representing the property to be bound.

    • removeProperty

      void removeProperty​(String name)
      Removes a property with the given name from the current request/response exchange context. After removal, subsequent calls to getProperty(java.lang.String) to retrieve the property value will return null.
      Parameters:
      name - a String specifying the name of the property to be removed.

    • getUri

      URI getUri()
      Get the request URI.
      Returns:
      request URI.

    • setUri

      void setUri​(URI uri)
      Set a new request URI.
      Parameters:
      uri - new request URI.

    • getMethod

      String getMethod()
      Get the request method.
      Returns:
      the request method.
      See Also:
      HttpMethod

    • setMethod

      void setMethod​(String method)
      Set the request method.
      Parameters:
      method - new request method.
      See Also:
      HttpMethod

    • getHeaders

      MultivaluedMap<String,​Object> getHeaders()
      Get the mutable request headers multivalued map.
      Returns:
      mutable multivalued map of request headers.
      See Also:
      getStringHeaders(), getHeaderString(String)

    • getStringHeaders

      MultivaluedMap<String,​String> getStringHeaders()
      Get a string view of header values associated with the message. Changes in the underlying headers map are reflected in this view.

      The method converts the non-string header values to strings using a RuntimeDelegate.HeaderDelegate if one is available via RuntimeDelegate.createHeaderDelegate(java.lang.Class) for the class of the value or using the values toString method if a header delegate is not available.

      Returns:
      response headers as a string view of header values.
      See Also:
      getHeaders(), getHeaderString(String)

    • getHeaderString

      String getHeaderString​(String name)
      Get a message header as a single string value. Each single header value is converted to String using a RuntimeDelegate.HeaderDelegate if one is available via RuntimeDelegate.createHeaderDelegate(java.lang.Class) for the header value class or using its toString method if a header delegate is not available.
      Parameters:
      name - the message header.
      Returns:
      the message header value. If the message header is not present then null is returned. If the message header is present but has no value then the empty string is returned. If the message header is present more than once then the values of joined together and separated by a ',' character.
      See Also:
      getHeaders(), getStringHeaders()

      Returns:
      the language of the entity or null if not specified

    • getMediaType

      MediaType getMediaType()
      Get the media type of the entity.
      Returns:
      the media type or null if not specified (e.g. there's no request entity).

    • getAcceptableMediaTypes

      List<MediaType> getAcceptableMediaTypes()
      Get a list of media types that are acceptable for the response.

      Returns:
      annotations attached to the entity instance.

      Set a new entity output stream. The JAX-RS runtime is responsible for closing the output stream.
