Detailed Description

Load task allows implementing custom asynchronous resource loading.

A load task is split into an optional LoadTask#loadFunction and mandatory LoadTask#finishFunction. Kanzi may execute the LoadTask#loadFunction in a background worker thread, instead of the main thread. And so only thread independent work should be done here. While the LoadTask#loadFunction is guaranteed to be called in the main thread. The load task execution happens in this order:

• The loading thread or main thread execute the LoadTask#loadFunction.
• The main thread executes the LoadTask#finishFunction.
• The load task returns the created resource with LoadTask#getResult.
