   16  * @ref avData "How To Manage Data"
   17  *
   18  * This API provides a data service to allow Apps to manage App-specific data on the AirVantage
   19  * server.
   20  *
   21  * @section le_avdata_binding IPC Interfaces Binding
   22  *
   23  * All the functions of this API are provided by the @b avcService platform service.
   24  *
   25  * Code sample for binding to avcService:
   26  * @verbatim
   27  bindings:
   28  {
   29     clientExe.clientComponent.le_avdata -> avcService.le_avdata
   30  }
   31  @endverbatim
   32  *
   33  *
   34  * @section le_avdata_overview AirVantage Data Overview
   35  *
   36  * Data is setup as @b Assets &mdash;  a collection of fields that can be managed by the AirVantage
   37  * server.
   38  *
   39  * An @b asset @b field is a single data point taken from a sensor that can be managed by the
   40  * AirVantage server.
   41  *
   42  * A field can be:
   43  * - @b variable allowing the AirVantage server to read the value, and can be read/writtten to by an App.
   44  * - @b setting allowing the AirVantage server to read/write the value, and can be read/written to by an App.
   45  * - @b command allowing the AirVantage server to invoke a function in the App.
   46  *
   47  * Fields are referred to by paths and need to follow these rules:
   48  *
   49  * - A parent path @b can't contain a field, parent path or child path that has the same name.
   50  * - Paths must be separated by a slash ("/") or a dot (".").
   51  * - When using a ("/") the path must start with a ("/") (e.g., /a/b/c)
   52  * - When using a (".") the path must start with the first field, (e.g., a.b.c)
   53  *
   54  * @note There is no leading "." when using "." delimiter.
   55  *
   56  * Variable and setting fields also have types. The available field types are:
   57  * - string
   58  * - integer
   59  * - float
   60  * - boolean
   61  *
   62  * Variable and setting fields have no default values. When they are first created with the
   63  * le_avdata_CreateResource() , all values are "null". They can also be set to "null" values with
   64  * the le_avdata_SetNull() .
   65  *
   66  * Fields do not have a fixed data type, so any of the SetInt/Float/Bool/String can
   67  * be called for a certain field to change its value and its type. However, A
   68  * GetInt/Float/Bool/String API must be called on a field with the matching type. In other words,
   69  * a Get API does not perform type-casting.
   70  *
   71  * @note If a user enters a value 0 for float data type, an error will be returned (LE_NOT_FOUND),
   72  * as the system infers 0 as an integer value and the data type doesn't match.  0.0 needs to be set
   73  * for the float data type to be zero.
   74  *
   75  * @section le_avdata_field Field Values and Activity
   76  *
   77  * Set functions are available to set field values (including "null"). Get functions are
   78  * available to get field values.
   79  *
   80  * An App can register a handler so that it can be called when an activity occurs on a field.
   81  * This is optional for variable and setting fields, but is @b required for command fields.
   82  * Registered handlers are called only when activities from AV server occurs. Client activities do
   83  * not trigger handlers.
   84  *
   85  * A handler registered with a command field is invoked with an optional argument list sent from the
   86  * AirVantage server. The APIs GetInt/Float/Bool/StringArg and le_avdata_GetStringArgLength() are
   87  * available to extract the arguments in the handler definition. AV server does not send argument
   88  * lists for handlers registered with variable and setting fields.
   89  *
   90  * A handler registered with a command field must call the le_avdata_ReplyExecResult() at the end of
   91  * its definition, in order to reply the command execution result to the AV server.
   92  *
   93  * Sometimes instead of waiting for activity to occur on a field, users may want to have their
   94  * application notify the server of their asset data details. Asset data can also be pushed from
   95  * the device to the server by using le_avdata_Push().
   96  *
   97  * This code sample shows how to push asset data to the server (assuming session is opened)
   98  *
   99  * @code
  100  * static void PushCallbackHandler
  101  * (
  102  *     le_avdata_PushStatus_t status,
  103  *     void* contextPtr
  104  * )
  105  * {
  106  *     if (status == LE_AVDATA_PUSH_SUCCESS)
  107  *     {
  108  *         // data pushed successfully
  109  *     }
  110  * }
  111  *
  112  * COMPONENT_INIT
  113  * {
  114  *       le_result_t result;
  115  *       result = le_avdata_CreateResource("/livingRoom/sensor1", LE_AVDATA_ACCESS_VARIABLE);
  116  *       if (result != LE_OK)
  117  *       {
  118  *           LE_FATAL("Error in creating livingRoom resource.");
  119  *       }
  120  *
  121  *       result = le_avdata_SetInt("/livingRoom/sensor1", 5) == LE_OK);
  122  *       if (result != LE_OK)
  123  *       {
  124  *           LE_FATAL("Failed to set value for livingRoom resource.");
  125  *       }
  126  *
  127  *       le_avdata_Push("/livingRoom/sensor1", PushCallbackHandler, NULL);
  128  * }
  129  * @endcode
  130  *
  131  * If users simply want to push a data dump to the server without creating resources,
  132  * le_avdata_PushStream() is available.
  133  * @note The push stream API has a limit of 20K.
  134  *
  135  * @code
  136  * COMPONENT_INIT
  137  * {
  138  *       int fd = open("data.txt", O_RDONLY);
  139  *       if (fd == -1)
  140  *       {
  141  *          LE_FATAL("Failed to open file.");
  142  *       }
  143  *
  144  *       // The data dump sent to the server will be display under <Path>
  145  *       le_avdata_PushStream("<Path>", fd, PushCallbackHandler, NULL);
  146  * }
  147  * @endcode
  148  *
  149  * @section le_avdata_namespace Namespace
  150  *
  151  * By default all asset data paths are created and managed under the application namespace.
  152  * Calling @c le_avdata_GetXXX / @c le_avdata_SetXXX/ le_avdata_AddResourceEventHandler() /
  153  * le_avdata_Push() with the path "/a/b/c" will search for the "/a/b/c" data under the apps
  154  * namespace. In order to query any paths created under an application namespace, user must append
  155  * the app name in front of the request on the server side. If creating asset data under application
  156  * namespace is not desired, users must call le_avdata_SetNamespace() and set the value to global.
  157  * An application that changes its namespace to global will be creating asset data in the global
  158  * space. All asset data API will use the last namespace set until the function is called again and
  159  * the namespace is set to something new.
  160  *
  161  * @note All asset data paths created by the application are deleted when it is stopped, even
  162  * the asset data created under global namespace. No asset data can therefore be persistent after
  163  * an application restart, regardless of the namespace used to create it.
  164  *
  165  * Example:
  166  *
  167  * @code
  168  * #define RESOURCE_A         "/test/resourceA"
  169  *
  170  * COMPONENT_INIT
  171  * {
  172  *     int intVal;
  173  *     LE_ASSERT(le_avdata_CreateResource(RESOURCE_A, LE_AVDATA_ACCESS_VARIABLE) == LE_OK);
  174  *     LE_ASSERT(le_avdata_SetInt(RESOURCE_A, 1) == LE_OK);
  175  *     LE_ASSERT(le_avdata_GetInt(RESOURCE_A, &intVal) == LE_OK);
  176  *     LE_ASSERT(intVal == 1); // value obtained under the application namespace
  177  *
  178  *     // Switch to global namespace
  179  *     LE_ASSERT(le_avdata_SetNamespace(LE_AVDATA_NAMESPACE_GLOBAL) == LE_OK);
  180  *
  181  *     LE_ASSERT(le_avdata_CreateResource(RESOURCE_A, LE_AVDATA_ACCESS_VARIABLE) == LE_OK);
  182  *     LE_ASSERT(le_avdata_SetInt(RESOURCE_A, 2) == LE_OK);
  183  *     LE_ASSERT(le_avdata_GetInt(RESOURCE_A, &intVal) == LE_OK);
  184  *     LE_ASSERT(intVal == 2); // value obtained under the global namespace
  185  * }
  186  * @endcode
  187  *
  188  * An application starts by creating a path "/test/resourceA" under the default application
  189  * namespace and sets it to 1. Then it sets the namespace to global and creates another path
  190  * "/test/resourceA" with a value of 2. A read request from the server on "<appName>/test/resourceA"
  191  * will return 1; whereas a read request on "/test/resourceA" will return 2.
  192  *
  193  * @section le_avdata_timeseries Time Series
  194  *
  195  * This feature enables user Apps to collect and keep in memory data when the device is off-line and
  196  * send the data to the AirVantage Server when the device is on-line.
  197  *
  198  * Time series records can be initialized using le_avdata_CreateRecord().
  199  * Data can be accumulated using the following data types along with a specified time stamp
  200  * (milliseconds elapsed since epoch).
  201  * - le_avdata_RecordInt()
  202  * - le_avdata_RecordFloat()
  203  * - le_avdata_RecordBool()
  204  * - le_avdata_RecordString()
  205  *
  206  * User apps can then open an @c avms session, and push the collected history data using
  207  * le_avdata_PushRecord(). The callback used when calling le_avdata_PushRecord() will indicate
  208  * whether the push has been successful or not.
  209  *
  210  * This code sample shows how to collect data and send to the server (assuming session is opened)
  211  *
  212  * @code
  213  *
  214  * static void PushCallbackHandler
  215  * (
  216  *     le_avdata_PushStatus_t status,
  217  *     void* contextPtr
  218  * )
  219  * {
  220  *     if (status == LE_AVDATA_PUSH_SUCCESS)
  221  *     {
  222  *         // data pushed successfully
  223  *     }
  224  * }
  225  *
  226  * static void SendData()
  227  * {
  228  *     struct timeval tv;
  229  *     uint64_t utcMilliSec;
  230  *     le_result_t result;
  231  *
  232  *     le_avdata_RecordRef_t recRef = le_avdata_CreateRecord();
  233  *
  234  *     gettimeofday(&tv, NULL);
  235  *     utcMilliSec = (uint64_t)(tv.tv_sec) * 1000 + (uint64_t)(tv.tv_usec) / 1000; // get current time
  236  *     result = le_avdata_RecordFloat(recRef, "speed", 0.08, utcMilliSec);
  237  *
  238  *     if (result == LE_OK)
  239  *     {
  240  *          le_avdata_PushRecord(recRef, PushCallbackHandler, NULL);
  241  *     }
  242  *
  243  *     le_avdata_DeleteRecord(recRef);
  244  * }
  245  * @endcode
  246  *
  247  * @section le_avdata_session User App Session Management
  248  *
  249  * An App can request to open a session and register a handler to get notified of a session
  250  * events. le_avdata_RequestSession() and le_avdata_ReleaseSession() can be used to
  251  * open a session and close a session respectively. If the session was initiated by an
  252  * user app, the session will be closed when all apps release their session reference.
  253  * le_avdata_AddSessionStateHandler() and le_avdata_RemoveSessionStateHandler() can be used to add
  254  * and remove notification handlers.
  255  *
  256  * @section le_avdata_fatal Fatal Behavior
  257  *
  258  * An invalid asset name or field name is treated as a fatal error (i.e. non-recoverable)
  259  * and will result in the client App being terminated.
