41 * @brief Both server and client must initialize the core platform by instantiating OCPlatform.
42 * On successful initialization, an instance of the OCPlatform is returned.
43 * APIs in OCPlatform provide mechanism to register a resource and host the resource
44 * on the server, find resources on the network etc.
50 * Constructor for OCPlatform. Constructs a new OCPlatform from a given PlatformConfig with
52 * @param config PlatformConfig struct which has details such as modeType (server/client/both),
53 * in-proc/out-of-proc etc.
55 OCPlatform(const PlatformConfig& config);
60 virtual ~OCPlatform(void);
63 * API for notifying core that resource's attributes have changed.
65 * @param OCResourceHandle resource handle of the resource
67 * @return OCStackResult return value of this API. Returns OC_STACK_OK if success.
68 * NOTE: This API is for server side only.
69 * NOTE: OCResourceHandle is defined in ocstack.h.
70 * NOTE: OCStackResult is defined in ocstack.h.
72 static OCStackResult notifyObservers(OCResourceHandle resourceHandle);
75 * API for Service and Resource Discovery.
76 * NOTE: This API applies to client side only.
78 * @param host - Host IP Address of a service to direct resource discovery query. If null or
79 * empty, performs multicast resource discovery query
80 * @param resourceURI - name of the resource. If null or empty, performs search for all resource names
81 * @param handler - Handles callbacks, success states and failure states.
83 * Four modes of discovery defined as follows:
84 * (NULL/Empty, NULL/Empty) - Performs ALL service discovery AND ALL resource discovery.
85 * (NULL/Empty, Not Empty) - Performs query for a filtered/scoped/particular resource(s)
87 * (Not Empty, NULL/Empty) - Performs ALL resource discovery on a particular service.
88 * (Not Empty, Not Empty) - Performs query for a filtered/scoped/particular resource(s)
89 * from a particular service.
91 * @return OCStackResult return value of this API. Returns OC_STACK_OK if success.
92 * NOTE: First parameter 'host' currently represents an IP address. This will change in future
93 * and will refer to endpoint interface so that we can refer to other transports such as BTH etc.
94 * NOTE: OCStackResult is defined in ocstack.h.
96 OCStackResult findResource(const std::string& host, const std::string& resourceURI,
97 std::function<void(OCResource::Ptr)> resourceHandler);
100 * This API registers a resource with the server
101 * NOTE: This API applies to server side only.
103 * @param resourceHandle - Upon successful registration, resourceHandle will be filled
104 * @param resourceURI - The URI of the resource. Example: "a/light". See NOTE below
105 * @param resourceTypeName - The resource type. Example: "light"
106 * @param resourceInterface - The resource interface (whether it is collection etc).
107 * @param entityHandler - entity handler callback.
108 * @param resourceProperty - indicates the property of the resource. Defined in ocstack.h.
109 * setting resourceProperty as OC_DISCOVERABLE will allow Discovery of this resource
110 * setting resourceProperty as OC_OBSERVABLE will allow observation
111 * settings resourceProperty as OC_DISCOVERABLE | OC_OBSERVABLE will allow both discovery and observation
113 * @return OCStackResult return value of this API. Returns OC_STACK_OK if success.
114 * NOTE: "a/light" is a relative URI.
115 * Above relative URI will be prepended (by core) with a host IP + namespace "oc"
116 * Therefore, fully qualified URI format would be //HostIP-Address/namespace/relativeURI"
117 * Example, a relative URI: 'a/light' will result in a fully qualified URI: //134.134.161.33/oc/a/light"
118 * First parameter can take a relative URI and core will take care of preparing the fully qualified URI
120 * first paramter can take fully qualified URI and core will take that as is for further operations
121 * NOTE: OCStackResult is defined in ocstack.h.

230 * Creates a resource proxy object so that get/put/observe functionality
231 * can be used without discovering the object in advance. Note that the
232 * consumer of this method needs to provide all of the details required to
233 * correctly contact and observe the object. If the consumer lacks any of
