Detailed Description

IO Driver.

Member Enumeration Documentation

anonymous enum

Use this flag in addition to the standard ones to skip any security check (i.e. token validation) Example: createIOHandler("/file.txt", O_RDONLY | IODriver::kInsecure, extras);

Enumerator
kInsecure

Constructor & Destructor Documentation

virtual dmlite::IODriver::~IODriver ( )

virtual

Virtual destructor.

Member Function Documentation

virtual IOHandler* dmlite::IODriver::createIOHandler ( const std::string &  pfn, 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.

static IOHandler* dmlite::IODriver::createIOHandler ( IODriver *  factory, const std::string &  pfn, int  flags, const Extensible &  extras, mode_t  mode = 0660  ) throw ( DmException )

static

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

String ID of the implementation.

Implements dmlite::BaseInterface.

virtual void dmlite::IODriver::setSecurityContext ( const SecurityContext *  ctx ) throw ( DmException )

protectedvirtual

Set the security context.

Reimplemented from dmlite::BaseInterface.

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