Class NSURLProtocol

  • All Implemented Interfaces:
    NSObject
    public class NSURLProtocol
extends NSObject
    NSURLProtocol NSURLProtocol is an abstract class which provides the basic structure for performing protocol-specific loading of URL data. Concrete subclasses handle the specifics associated with one or more protocols or URL schemes.

      • canInitWithRequest

        public static boolean canInitWithRequest​(NSURLRequest request)
        canInitWithRequest: This method determines whether this protocol can handle the given request. A concrete subclass should inspect the given request and determine whether or not the implementation can perform a load with that request. This is an abstract method. Sublasses must provide an implementation.
        Parameters:
        request - A request to inspect.
        Returns:
        YES if the protocol can handle the given request, NO if not.

      • canonicalRequestForRequest

        public static NSURLRequest canonicalRequestForRequest​(NSURLRequest request)
        canonicalRequestForRequest: This method returns a canonical version of the given request. It is up to each concrete protocol implementation to define what "canonical" means. However, a protocol should guarantee that the same input request always yields the same canonical form. Special consideration should be given when implementing this method since the canonical form of a request is used to look up objects in the URL cache, a process which performs equality checks between NSURLRequest objects.

        This is an abstract method; sublasses must provide an implementation.

        Parameters:
        request - A request to make canonical.
        Returns:
        The canonical form of the given request.

        public static java.lang.Object propertyForKeyInRequest​(java.lang.String key,
                                                       NSURLRequest request)
        propertyForKey:inRequest: Returns the property in the given request previously stored with the given key. The purpose of this method is to provide an interface for protocol implementors to access protocol-specific information associated with NSURLRequest objects.
        Parameters:
        key - The string to use for the property lookup.
        request - The request to use for the property lookup.
        Returns:
        The property stored with the given key, or nil if no property had previously been stored with the given key in the given request.

      • registerClass

        public static boolean registerClass​(org.moe.natj.objc.Class protocolClass)
        registerClass: This method registers a protocol class, making it visible to several other NSURLProtocol class methods. When the URL loading system begins to load a request, each protocol class that has been registered is consulted in turn to see if it can be initialized with a given request. The first protocol handler class to provide a YES answer to +canInitWithRequest: "wins" and that protocol implementation is used to perform the URL load. There is no guarantee that all registered protocol classes will be consulted. Hence, it should be noted that registering a class places it first on the list of classes that will be consulted in calls to +canInitWithRequest:, moving it in front of all classes that had been registered previously.

        A similar design governs the process to create the canonical form of a request with the +canonicalRequestForRequest: class method.

        Parameters:
        protocolClass - the class to register.
        Returns:
        YES if the protocol was registered successfully, NO if not. The only way that failure can occur is if the given class is not a subclass of NSURLProtocol.

      • removePropertyForKeyInRequest

        public static void removePropertyForKeyInRequest​(java.lang.String key,
                                                 NSMutableURLRequest request)
        removePropertyForKey:inRequest: Remove any property stored under the given key Like setProperty:forKey:inRequest: above, the purpose of this method is to give protocol implementors the ability to store protocol-specific information in an NSURLRequest
        Parameters:
        key - The key whose value should be removed
        request - The request to be modified

      • requestIsCacheEquivalentToRequest

        public static boolean requestIsCacheEquivalentToRequest​(NSURLRequest a,
                                                        NSURLRequest b)
        requestIsCacheEquivalent:toRequest: Compares two requests for equivalence with regard to caching. Requests are considered euqivalent for cache purposes if and only if they would be handled by the same protocol AND that protocol declares them equivalent after performing implementation-specific checks.
        Returns:
        YES if the two requests are cache-equivalent, NO otherwise.

        setProperty:forKey:inRequest: Stores the given property in the given request using the given key. The purpose of this method is to provide an interface for protocol implementors to customize protocol-specific information associated with NSMutableURLRequest objects.
        Parameters:

        initWithRequest:cachedResponse:client: Initializes an NSURLProtocol given request, cached response, and client.
        Parameters:
        request - The request to load.
        cachedResponse - A response that has been retrieved from the cache for the given request. The protocol implementation should apply protocol-specific validity checks if such tests are necessary.
        client - The NSURLProtocolClient object that serves as the interface the protocol implementation can use to report results back to the URL loading system.

      • request

        public NSURLRequest request()
        Returns the NSURLRequest of the receiver.
        Returns:
        The NSURLRequest of the receiver.

      • startLoading

        public void startLoading()
        startLoading Starts protocol-specific loading of a request. When this method is called, the protocol implementation should start loading a request.

      • stopLoading

        public void stopLoading()
        stopLoading Stops protocol-specific loading of a request. When this method is called, the protocol implementation should end the work of loading a request. This could be in response to a cancel operation, so protocol implementations must be able to handle this call while a load is in progress.
