CLogWrapper Class Reference

class CLogWrapper : public CBase

The log wrapper.

As some UI variants do not use a Log Engine, the log wrapper provides a consistent interface to clients that need to work, without being changed, with multiple UI variants.

The log wrapper is provided in its own DLL, the logwrap.dll.

If a Log Engine is not installed on a phone, the log wrapper creates an instance of the CLogBase class, whose event handling requests complete with KErrNotSupported and whose functions return KErrNotSupported.

If a Log Engine is installed on a phone, the log wrapper creates an instance of the CLogClient class, provided in a separate DLL, the logcli.dll . The CLogClient class derives from CLogBase and provides implementations for the event handling requests and functions.
