		int	flags,
		const Extensible &	extras,
		mode_t	mode = 0660
	)			throw (DmException) [virtual]

Instantiate a implementation of IOHandler

Parameters:

	pfn	The file name.
	flags	The open mode. See man 2 open.
	extras	As was given by the PoolHandler.
	mode	When called with O_CREAT, it will be used to create the file.

virtual void dmlite::IODriver::doneWriting

(

const Location &

loc

)

throw (DmException) [virtual]

Must be called when the front-end is done writing.

Parameters:

	pfn	The file name.
	loc	The Location object as returned by whereToWrite

virtual std::string dmlite::IODriver::getImplId

(

void

)

const throw () [pure virtual]

Implements dmlite::BaseInterface.

static void dmlite::IODriver::setSecurityContext	(	IODriver *	i,
		const SecurityContext *	ctx
	)			throw (DmException) [static, protected]

virtual void dmlite::IODriver::setSecurityContext

(

const SecurityContext *

ctx

)

throw (DmException) [protected, virtual]
