LiveTextFeed Entity

The LiveTextFeed entity has the following properties:

  • Id int:(read only) The identifier and primary key of the LiveTextFeed instance.

  • Name string: The user-defined name of the LiveTextFeed instance. This alternate key must be unique in the scope of the BSN account.

  • PhysicalPath string:(read only) The external URL of the associated RSS file in persistent storage.

  • FileSize long:(read only) The size of the associated RSS file in bytes.

  • FileHash string:(read only): A SHA1 hash of the associated RSS file contents.

  • CreationDate DateTime:(read only) A UTC timestamp indicating when the Live Text Feed was created in the BrightSign Network.

  • Contents Dictionary<string,string>: A list of key-value pairs that make up the Live Text Feed. This list is set to Null when not initialized by the server.

  • Presentations PresentationInfo[]:(read only) An array of PresentationInfo structures that denote parent presentations.

  • Items LiveTextFeedItem[]: An array of LiveTextFeedItem entity-relations that reference individual items within the Live Text Feed. This list is set to Null when not initialized by the server.

LiveTextFeedItem Entity-Relation

The LiveTextFeedItem entity-relation represents a single Live Text Feed item. It has the following properties:

  • Title string: The key (RSS item title) of the item in the associated Live Text Feed.

  • Description string: The value (RSS item description) of the item in the associated Live Text Feed.

  • ValidityStartDate DateTime: A value that determines the validity start date for the item (i.e. the point at which the item will start being displayed in the Live Text Feed). A Null value determines that the item is valid from the moment it is added to the Live Text Feed; this is the standard case for most items.

  • ValidityEndDate DateTime: A value that determines the validity end date for the associated item (i.e. the point at which the item will no longer be displayed in the Live Text Feed). A Null value determines that the item will be valid until it is removed from the Live Text Feed manually by the user; this is the standard case for most items.

Live Text Feed Management Web Methods

PagedList<LiveTextFeed> GetLiveTextFeeds(string marker, int pageSize)

Retrieves the next page of the LiveTextFeed list, sorted by Name string. The returned list will contain no more items than the defined page size.

Required Permissions

Live Text Feed: View Live Text Feeds

Parameters

  • marker string: The Name  string of the last LiveTextFeed instance on the previous page. If the value is Null, then the method will retrieve the first page.

  • pageSize int: The maximum number of objects returned by the method. If the list of objects that match the search criteria exceeds the pageSize int limit, the returned list will indicate that it is truncated. If the integer is not positive, then the method will return the maximum allowed number of objects. Attempting to request more objects than is allowed will lead to the same result, but without an error.

List<LiveTextFeed> GetSpecifiedLiveTextFeeds(int[] liveTextFeedIds)

Retrieves a list of LiveTextFeed instances matching the specified identifiers, sorted by Name string. The identifiers of nonexistent LiveTextFeed instances will be ignored.

Required Permissions

Live Text Feed: View Live Text Feeds

Parameters

  • liveTextFeedIds int[]: An array of Id int values for the LiveTextFeed instances being requested. The number of returned items is limited to 100 by the server. Attempting to request more than the maximum allowed number of objects will cause an error, while passing an empty array will lead to an immediate empty response without an error.

PagedList<LiveTextFeed> FindLiveTextFeeds(string namePattern, string marker, int pageSize)

Retrieves the next page of a LiveTextFeed list containing names matched with the specified pattern. The returned list is organized by Name string and may not contain more items than the defined page size.

Parameters

  • namePattern string: The exact Name string of the LiveTextFeed instance (or its wildcard-based pattern). Supported wildcards currently include “*”, “?”, and “[‘and’]”.

  • marker string: The Name string of the last LiveTextFeed instance on the previous page. If the value is Null, then the method will retrieve the first page.

  • pageSize int: The maximum number of objects returned by the method. If the list of objects that match the search criteria exceeds the pageSize int limit, the returned list will indicate that it is truncated. If the integer is not positive, then the method will return the maximum allowed number of objects. Attempting to request more objects than is allowed will lead to the same result, but without an error.
