CCoeFepLoader Class Reference

class CCoeFepLoader : public CActive

The CCoeFepLoader class implements a FEP loader for internal use by Cone. It loads the front-end processor in a high-priority active object which is run as soon as the active-scheduler starts. This enables the front-end processor to be set up before it is loaded.

Member Functions Documentation

DoCancel()

void DoCancel ( ) [private, virtual]

Implements cancellation of an outstanding request.

This function is called as part of the active object's Cancel() .

It must call the appropriate cancel function offered by the active object's asynchronous service provider. The asynchronous service provider's cancel is expected to act immediately.

DoCancel() must not wait for event completion; this is handled by Cancel() .

NewL(CCoeEnv &, CCoeFepLoader *&)

CCoeFepLoader *& aOwner

Parameters

CCoeEnv & aCoeEnv
CCoeFepLoader *& aOwner

RunError(TInt)

TInt RunError ( TInt aError ) [private, virtual]

Parameters

TInt aError

RunL()

void RunL ( ) [private, virtual]

Handles an active object's request completion event.

A derived class must provide an implementation to handle the completed request. If appropriate, it may issue another request.

The function is called by the active scheduler when a request completion event occurs, i.e. after the active scheduler's WaitForAnyRequest() function completes.

Before calling this active object's RunL() function, the active scheduler has:

1. decided that this is the highest priority active object with a completed request

2. marked this active object's request as complete (i.e. the request is no longer outstanding)

RunL() runs under a trap harness in the active scheduler. If it leaves, then the active scheduler calls RunError() to handle the leave.

Note that once the active scheduler's Start() function has been called, all user code is run under one of the program's active object's RunL() or RunError() functions.
