Detailed Description
To use this type, create a CustomLocationDataSource and implement the startCallback and stopCallback in JavaScript.
Property Documentation
startCallback : var |
The callback function that is called when a request to AbstractLocationDataSource::start() the data source is recieved.
At the end of the JavaScript callback, call AbstractLocationDataSource::onStartCompleted() with an optional error message.
For example, an implementation using PositionSource and Compass would call:
positionSource.start(); compass.start(); onStartCompleted();
stopCallback : var |
The callback function that is called when a request to AbstractLocationDataSource::stop() the data source is recieved.
At the end of the JavaScript callback, call AbstractLocationDataSource::onStopCompleted().
For example, an implementation using PositionSource and Compass would call:
positionSource.stop(); compass.start(); onStopCompleted();
Signal Documentation
