Inheritance diagram for TWebSystem:

Constructor & Destructor Documentation

TWebSystem()

TWebSystem::TWebSystem

(

)

Create helper class that allows directory access via httpd.

The name must start with '-' to bypass the TSystem singleton check.

Definition at line 1440 of file TWebFile.cxx.

~TWebSystem()

virtual TWebSystem::~TWebSystem ( )

inlinevirtual

Definition at line 107 of file TWebFile.h.

Member Function Documentation

AccessPathName()

Bool_t TWebSystem::AccessPathName ( const char *  path, EAccessMode  mode  )

virtual

Returns FALSE if one can access a file using the specified access mode.

Mode is the same as for the Unix access(2) function. Attention, bizarre convention of return value!!

Reimplemented from TSystem.

Definition at line 1531 of file TWebFile.cxx.

FreeDirectory()

void TWebSystem::FreeDirectory ( void *  dirp )

virtual

Free directory via httpd.

Reimplemented from TSystem.

Definition at line 1474 of file TWebFile.cxx.

GetDirEntry()

const char * TWebSystem::GetDirEntry ( void *  dirp )

virtual

Get directory entry via httpd. Returns 0 in case no more entries.

Reimplemented from TSystem.

Definition at line 1487 of file TWebFile.cxx.

GetDirPtr()

void * TWebSystem::GetDirPtr ( ) const

inlineprivatevirtual

Reimplemented from TSystem.

Definition at line 103 of file TWebFile.h.

GetPathInfo()

Int_t TWebSystem::GetPathInfo ( const char *  path, FileStat_t &  buf  )

virtual

Get info about a file.

Info is returned in the form of a FileStat_t structure (see TSystem.h). The function returns 0 in case of success and 1 if the file could not be stat'ed.

Reimplemented from TSystem.

Definition at line 1503 of file TWebFile.cxx.

MakeDirectory()

Int_t TWebSystem::MakeDirectory ( const char *  name )

virtual

Make a directory via httpd. Not supported.

Reimplemented from TSystem.

Definition at line 1450 of file TWebFile.cxx.

OpenDirectory()

void * TWebSystem::OpenDirectory ( const char *  name )

virtual

Open a directory via httpd.

Returns an opaque pointer to a dir structure. Returns 0 in case of error.

Reimplemented from TSystem.

Definition at line 1459 of file TWebFile.cxx.

Unlink()

Int_t TWebSystem::Unlink ( const char *  path )

virtual

Unlink, i.e.

remove, a file or directory. Returns 0 when successful, -1 in case of failure. Not supported for httpd.

Reimplemented from TSystem.

Definition at line 1546 of file TWebFile.cxx.
