Detailed Description

Class UnixFileLogDriver

UnixfileLogdriver will log into a file, that is not createtd at the moment If several components chose to log in the same file, it will work with this driver UnixFileLogDriver is not thread safe (the whole framework is not)

[virtual]

Destructor If _isCloned is false, it will close all descriptors in the FDMap

Constructor for the first UnixFileLogDriver object Constructor will register the object by the MRC with the name UnixFileLogDriver

[const virtual]

Method that is called by the MRC to duplicate the whole object

Reimplemented from LogDriver.

[virtual]

Parameters:

message

Message that will be logged in the file If logger object was not initialized properly, this method will only throw an exception

Reimplemented from LogDriver.

[virtual]

Parameters:

logDriverParameters

The parameter has to be in the form file:filename, for example file:/tmp/foo If the specified file already exists or it cannot be created, this method will throw an exception and the UnixFileLogDriver object will not work. If the file was already opened by another component of the same process, logging will work properly.

Reimplemented from LogDriver.

Constructor used in the clone Method to create a clone of the current object according to the prototype pattern

[private const]

Computes the position of a file for the index in the map
