Tizen API

This API provides common Tizen functionality.

The API provides the basic definitions that are used in the Tizen Web Device API. These include generic callbacks that are invoked when the operations succeed or fail, WebAPIError and WebAPIException that give information of the platform's error and filter interfaces that are used to make query statements for searching.

Additionally, this API specifies the location in the ECMAScript hierarchy in which the Tizen Web Device API is instantiated (window.tizen).

For more information on the Tizen features, see Tizen Guide.

1. Type Definitions

1.1. FilterMatchFlag

Filter match flags.
  enum FilterMatchFlag { "EXACTLY", "FULLSTRING", "CONTAINS", "STARTSWITH", "ENDSWITH", "EXISTS" };

Since: 1.0

These values are supported:

  • EXACTLY - Indicates that an attribute value should match exactly with the specified default value. For strings, this type of comparison is case-sensitive.
  • FULLSTRING - Indicates String-based comparison and that the attribute value should match the whole string (case insensitive).
  • CONTAINS - Indicates that an attribute value should contain the specified string. This type of comparison works only on strings and is case insensitive.
  • STARTSWITH - Indicates that an attribute value should start with the specified string. This type of comparison works only on strings and is case insensitive.
  • ENDSWITH - Indicates that an attribute value should end with the specified string. This type of comparison works only on strings and is case insensitive.
  • EXISTS - Indicates that a filter comparison should match if the specified attribute exists.

1.2. SortModeOrder

An enumerator that indicates the sorting order.
  enum SortModeOrder { "ASC", "DESC" };

Since: 1.0

The following values are supported:

  • ASC - Indicates that the sorting order is ascending
  • DESC - Indicates that the sorting order is descending

1.3. CompositeFilterType

An enumerator that indicates the type of composite filter.
  enum CompositeFilterType { "UNION", "INTERSECTION" };

Since: 1.0

The following values are supported:

  • UNION - Indicates that the composite is a union of filters ("OR" operator)
  • INTERSECTION - Indicates that the composite is an intersection of filters ("AND" operator)

2. Interfaces

2.1. TizenObject

Defines the tizen interface as a part of the window global object.
  [NoInterfaceObject] interface TizenObject {
    readonly attribute Tizen tizen;
  };
  Window implements TizenObject;

Since: 1.0

The Tizen interface is always available within the Window object in the ECMAScript hierarchy.

2.2. Tizen

The root of the Tizen Web Device API.
  [NoInterfaceObject] interface Tizen {
  };

Since: 1.0

This is the Tizen root interface. It is a property of the ECMAScript global object, as specified by the TizenObject interface.

2.3. AbstractFilter

This is a common interface used by different types of object filters.
  [NoInterfaceObject] interface AbstractFilter {
  };

Since: 1.0

Never use this base interface directly, instead use AbstractFilter subtypes, such as AttributeFilter, AttributeRangeFilter, and CompositeFilter.

2.4. AttributeFilter

This interface represents a set of filters.
  [Constructor(DOMString attributeName, optional FilterMatchFlag? matchFlag, optional any matchValue)]
  interface AttributeFilter : AbstractFilter {
    attribute DOMString attributeName;

    attribute FilterMatchFlag matchFlag setraises(WebAPIException);

    attribute any matchValue;
  };

Since: 1.0

It represents the query statement for the specified value of matchValue by the rule of matchFlag.

If no matchValue is defined, the filter matches all objects that have the attribute defined (same as the "EXISTS" filter works), otherwise, it only matches objects which have an attribute that match the specified value.

Code example:

 // The following example retrieves all songs from the album "The Joshua Tree".
 var count = 100;
 var offset = 0;
 var albumFilter = new tizen.AttributeFilter("album", "EXACTLY", "The Joshua Tree");

 function errorCB(err) {
     console.log( 'The following error occurred: ' +  err.name);
 }

 function findCB(contents) {
     console.log('The Joshua Tree :' + contents.length);
 }

 tizen.content.find(findCB, errorCB, null, albumFilter, null, count, offset);
 

Constructors

AttributeFilter(DOMString attributeName, optional FilterMatchFlag? matchFlag, optional any matchValue);

Attributes

  • DOMString attributeName
    The name of the object attribute used for filtering.

    This is the name of the object attribute exactly as it is defined in the object's interface. For attributes of complex type, use fully-qualified names (such as 'geolocation.latitude' to filter a video or image content's latitude in a geolocation).

    For attributes of an array type, the filter will match if any value in the array matches.

    Since: 1.0

  • FilterMatchFlag matchFlag
    The match flag used for attribute-based filtering.

    By default, this attribute is set to "EXACTLY".

    Since: 1.0

  • any matchValue
    The value used for matching.

    The filter will match if the attribute value matches the given matchValue.

    This value is not used if the matchFlag is set to "EXISTS". By default, this attribute is set to null.

    Since: 1.0

2.5. AttributeRangeFilter

AttributeRangeFilter represents a filter based on an object attribute which has values that are within a particular range.
  [Constructor(DOMString attributeName, optional any initialValue, optional any endValue)]
  interface AttributeRangeFilter : AbstractFilter {
    attribute DOMString attributeName;

    attribute any initialValue;

    attribute any endValue;
  };

Since: 1.0

Range filters, where only one boundary is set, are available.

Code example:

 var count = 100;
 var offset = 0;
 // Use the modifiedDate attribute with a range that starts today and ends in 1 day
 // (meaning that you search for all contents modified today)
 var today = new Date();
 var today_begin = new Date(today.getFullYear(), today.getMonth(),today.getDate());
 var today_end = new Date(today.getFullYear(), today.getMonth(),today.getDate()+1);
 var dateRangeFilter = new tizen.AttributeRangeFilter("modifiedDate", today_begin, today_end);

 function errorCB(err) {
     console.log( 'The following error occurred: ' +  err.name);
 }

 function findCB(contents) {
     console.log('The contents modified today :' + contents.length);
 }

 tizen.content.find(findCB, errorCB, null, dateRangeFilter, null, count, offset);
 

Constructors

AttributeRangeFilter(DOMString attributeName, optional any initialValue, optional any endValue);

Attributes

  • DOMString attributeName
    The name of the object attribute used for filtering.

    The value of this attribute is exactly as it is defined in the object's interface. For attributes of complex type, use fully-qualified names (such as 'geolocation.latitude' to filter a video or image content's latitude in a geolocation).

    For attributes of array type, the filter will match if any value in the array matches.

    Since: 1.0

  • any initialValue
    Objects with an attribute that is greater than or equal to initialValue will match.

    By default, this attribute is set to null.

    Since: 1.0

  • any endValue
    Objects with an attribute that is strictly lower than or equal to endValue will match.

    By default, this attribute is set to null.

    Since: 1.0

2.6. CompositeFilter

CompositeFilter represents a set of filters.
  [Constructor(CompositeFilterType type, optional AbstractFilter[]? filters)]
  interface CompositeFilter : AbstractFilter {

    attribute CompositeFilterType type;

    attribute AbstractFilter[] filters;
  };

Since: 1.0

The composite filters can be one of the following 2 types:

  • The union - used to filter objects that match any of the filters it includes.
  • The intersection - used to filter objects that match all the filters it includes.

Code example:

 // The following example retrieves all songs from the album "The Joshua Tree", by artist "U2".
 var count = 100;
 var offset = 0;
 var artistFilter = new tizen.AttributeFilter("artists", "EXACTLY", "U2");
 var albumFilter = new tizen.AttributeFilter("album", "EXACTLY", "The Joshua Tree");
 var filter = new tizen.CompositeFilter("INTERSECTION", [albumFilter, artistFilter]);

 function errorCB(err) {
     console.log( 'The following error occurred: ' +  err.name);
 }

 function findCB(contents) {
     console.log('The Joshua Tree by U2:' + contents.length);
 }

 tizen.content.find(findCB, errorCB, null, filter, null, count, offset);
 

Code example:

 // The following example retrieves all songs from the album "Tormato" and all songs by artist "Rush".
 var count = 100;
 var offset = 0;
 var artistFilter = new tizen.AttributeFilter("artists", "EXACTLY", "Rush");
 var albumFilter = new tizen.AttributeFilter("album", "EXACTLY", "Tormato");
 var filter = new tizen.CompositeFilter("UNION", [albumFilter, artistFilter]);

 function errorCB(err) {
     console.log( 'The following error occurred: ' +  err.name);
 }

 function findCB(contents) {
     console.log('Songs found:' + contents.length);
 }

 tizen.content.find(findCB, errorCB, null, filter, null, count, offset);
 

Constructors

CompositeFilter(CompositeFilterType type, optional AbstractFilter[]? filters);

Attributes

  • CompositeFilterType type
    The composite filter type.

    Since: 1.0

  • AbstractFilter[] filters
    The list of filters in the composite filter.

    Since: 1.0

2.7. SortMode

SortMode is a common interface used for sorting of queried data.
  [Constructor(DOMString attributeName, optional SortModeOrder? order)]
  interface SortMode {
    attribute DOMString attributeName;

    attribute SortModeOrder order setraises(WebAPIException);
  };

Since: 1.0

Note that the sorting result of list type attributes is not determined.

Code example:

 // The following example retrieves all songs from the album "The Joshua Tree", by artist "U2", ordered by the track number.
 var count = 100;
 var offset = 0;
 var sortMode = new tizen.SortMode("trackNumber", "ASC");
 var artistFilter = new tizen.AttributeFilter("artists", "EXACTLY", "U2");
 var albumFilter = new tizen.AttributeFilter("album", "EXACTLY", "The Joshua Tree");
 var filter = new tizen.CompositeFilter("INTERSECTION", [albumFilter, artistFilter]);

 function errorCB(err) {
     console.log( 'The following error occurred: ' +  err.name);
 }

 function printContent(content, index, contents) {
     console.log('Track: ' + content.trackNumber + ' Title: ' + content.title + 'Duration: ' + content.duration + 'URL: ' + content.contentURI + 'MIME: ' + content.mimeType);
 }

 function findCB(contents) {
     console.log('The Joshua Tree by U2:');
     contents.forEach(printContent);
     // Increase the offset as much as the count and then find content again.
     if (contents.length == count) {
         offset += count;
         tizen.content.find(findCB, errorCB, null, filter, sortMode, count, offset);
     }
 }

 tizen.content.find(findCB, errorCB, null, filter, sortMode, count, offset);
 

Constructors

SortMode(DOMString attributeName, optional SortModeOrder? order);

Attributes

  • DOMString attributeName
    The name of the object attribute used for sorting.

    Since: 1.0

  • SortModeOrder order
    The type of the sorting.

    By default, this attribute is set to ASC.

    Since: 1.0

2.8. SimpleCoordinates

SimpleCoordinates represents a point (latitude and longitude) in the map coordinate system.
  [Constructor(double latitude, double longitude)]
  interface SimpleCoordinates {
    attribute double latitude setraises(WebAPIException);

    attribute double longitude setraises(WebAPIException);
  };

Since: 1.0

Latitude and longitude are of the WGS84 datum.

Code example:

   // This example utilizes methods from Tizen's HAM module to get current latitude and longitude.
   var myPosition;

   // reads current position from the GPS module.
   function onChangedCB(info) {
     var latitude, longitude;
     latitude = info.gpsInfo[0].latitude;
     longitude = info.gpsInfo[0].longitude;

     // packs these values in one variable:
     myPosition = new SimpleCoordinates(latitude, longitude);
   }

   // starts monitoring GPS info periodically.
   try {
     tizen.humanactivitymonitor.start("GPS", onChangedCB, {callbackInterval: 120000, sampleInterval: 60000});
   } catch (err) {
     console.log(err.name + ": " + err.message);
   }
 

Constructors

SimpleCoordinates(double latitude, double longitude);

    const unsigned short NO_MODIFICATION_ALLOWED_ERR = 7;
    const unsigned short NOT_FOUND_ERR = 8;
    const unsigned short NOT_SUPPORTED_ERR = 9;
    const unsigned short INUSE_ATTRIBUTE_ERR = 10; 
    const unsigned short INVALID_STATE_ERR = 11;

      Since: 2.0

    2.10. WebAPIError

    Generic error interface.
      [NoInterfaceObject]
      interface WebAPIError {

    • readonly DOMString message
      An error message that describes the details of the error encountered.

      This attribute is not intended to be used directly in the user interfaces as it is mainly intended to be useful for developers rather than end users.

      Since: 2.0

    2.11. SuccessCallback

    This interface is used in methods that do not require any return value in the success callback.
      [Callback=FunctionOnly, NoInterfaceObject]
      interface SuccessCallback {
        void onsuccess ();
      };

    Since: 1.0

    In case of successful execution of an asynchronous call, SuccessCallback or an API defined callback must be called immediately to notify the user.

    Code example:

         // This example assumes that the application "MyFiles"
         // has been installed correctly and can be launched.
    
         function onSuccess() {
             console.log("Application launched successfully");
         }
    
         // the ID of launched application.
         var otherAppID = '0pnxz8hbsr.MyFiles';
    
         tizen.application.launch(otherAppID, onSuccess);
     

    Methods

    onsuccess
    Method invoked when the asynchronous call completes successfully.
    void onsuccess();
                 

    Since: 1.0

    2.12. ErrorCallback

    This interface is used in methods that require only an error as an input parameter in the error callback.
      [Callback=FunctionOnly, NoInterfaceObject]
      interface ErrorCallback {
    
        void onerror (WebAPIError error);
      };

    Since: 1.0

    If an invalid function (such as null) is passed to the API that accepts ErrorCallback, it silently fails and there is no further action.

    Code example:

      // This example assumes that the application "NonexistentApp"
      // has not been installed and can not be launched.
    
      // Define the error callback.
      function onerror(error) {
        console.log(error.message);
      }
      function onsuccess() {
          console.log("The application has launched successfully");
      }
    
      // the ID of non-existing application.
      var bogusAppID = "NonexistentApp.main";
    
      tizen.application.launch(bogusAppID, onsuccess, onerror);
     

    Methods

    onerror
    Method that is invoked when an error occurs.
    void onerror(WebAPIError error);
                 

    Since: 1.0

    Parameters:

    • error: Generic error.
