CScheduledTask Class Reference

class CScheduledTask : public CBase

The representation of a scheduled task that is passed to registered programs.

When tasks are due, the Task Scheduler encapsulates task information within CScheduledTask objects, and externalises them to a direct file store.

The root stream of the direct file store contains a 32 bit value, followed by the external representations of one or more CScheduledTask objects. The 32 bit value is interpreted as a TInt32 and contains the number of CScheduledTask objects that follow in the stream.

The registered program can create successive CScheduledTask objects from this stream using the static NewLC() function.
