Constructor & Destructor Documentation

File::File (  const char *  name, const char *  mode )

Constructor. Parameters: name  File name or path. If it is a relative path, it is assumed to be relative to the path for configuration files. Otherwise, the path is used directly. mode  File open mode as used by fopen defined in stdio.h. Definition at line 14 of file File.cpp. References ASSERT, buf, bufSize, getGTDir(), index, isWrite, and stream.

Here is the call graph for this function:

File::~File (   )

Destructor. Definition at line 32 of file File.cpp. References buf, index, isWrite, stream, and VERIFY.

Member Function Documentation

void File::read (  void *  p, unsigned  size )

The function read a number of bytes from the file to a certain memory location. Parameters: p  The start of the memory space the data is written to. size  The number of bytes read from the file. Definition at line 42 of file File.cpp. References ASSERT, buf, bufSize, index, isWrite, and stream. Referenced by InFile::readFromStream().

void File::write (  const void *  p, unsigned  size )

The function writes a number of bytes from a certain memory location into the file. Parameters: p  The start of the memory space the data is read from. size  The number of bytes written into the file. Definition at line 60 of file File.cpp. References buf, index, stream, and VERIFY. Referenced by OutFile::writeToStream().

void File::printf (  const char *  format, ...  )

The function implements printf for the stream represented by instances of this class. Parameters: format  Format string as used by printf defined in stdio.h. ...  See printf in stdio.h. Definition at line 74 of file File.cpp. References ASSERT, index, and stream.

bool File::exists (   )  const [inline]

The function returns whether the file represented by an object of this class actually exists. Returns: The existence of the file. Definition at line 72 of file File.h. References stream. Referenced by OutFile::exists(), and InFile::exists().

bool File::eof (   )  const

The function returns whether the end of the file represented by an object of this class was reached. Returns: End of file reached? Definition at line 83 of file File.cpp. References bufSize, index, and stream. Referenced by InFile::getEof().

char * File::getGTDir (   )  [static]

The function returns the current GT directory, e.g. /MS/OPENR/APP or <...>/GT2003 or /usr/local/GT2003 Returns: The current GTDir Definition at line 92 of file File.cpp. Referenced by File().
