CLbtTriggerEntry Class Reference

class CLbtTriggerEntry : public CBase

Abstract base class for location triggering entries.

It provides methods to determine the trigger type and to define basic trigger attributes. The following attributes are defined in location triggering entries.

Id Defines the identity of a trigger. The Id is allocated by Location Triggering Server and it's unique among all triggers currently exist in the system. If a trigger is removed from the system, its Id may be reused by another trigger. This attribute can not be modified after the trigger is created.

Name The name attribute defines a human-readable name for the trigger. The purpose of the name attribute is mainly for the end user to be able to identify the trigger in the UI. The maximum length of the name is KLbtMaxNameLength characters. This attribute can be modified after the trigger is created.

State This attribute specifies if the trigger is enabled or disabled. A disabled trigger is not supervised by the Location Triggering Server and thus will never be fired. This attribute can be modified after the trigger is created.

Requestors The requestors attribute consists of a requestor stack with contacts and/or services using the location service. Requestor information is used for privacy queries when trigger is created and fired. Requestor information is not allowed to be changed once the trigger has been created.

Manager UI . Manager UI is the UI application that can view, edit and delete the trigger. Manager UI application shall be provided by the user of this API. If it's possible, client application must specify the manager UI application when the trigger is created. Note, Manager UI may be different from the trigger's owner. Trigger's owner is the process that created the trigger. Triggers can be directly accessed by the Manager UI application. Although this attribute is not mandatory when creating a trigger. it's highly recommended that it is specified. It cannot be modified after the trigger is created.

Trigger condition . Trigger condition specifies in what situation a trigger shall be fired. Current system supports only basic trigger condition. Basic trigger condition is defined by a trigger area and direction of terminal's movement. Only circular area can be used as trigger area in current system. This attribute can be modified after the trigger is created.
