Member Function Documentation

virtual char* VCF::LinuxFileStream::getBuffer (   )  [virtual]

returns a pointer to the buffer that represents the file contents Implements VCF::FileStreamPeer.

virtual uint64 VCF::LinuxFileStream::getSize (   )  [virtual]

returns the size of the file stream in bytes Implements VCF::FileStreamPeer.

virtual uint64 VCF::LinuxFileStream::read (  unsigned char *  bytesToRead, uint64  sizeOfBytes )  [virtual]

reads sizeOfBytes bytes from the stream into the buffer bytesToRead Parameters: char*  a buffer of at least sizeOfBytes long. This must be allocated by the caller. uint32  the number of bytes to read from the file, starting at the current seek position. Implements VCF::FileStreamPeer.

virtual void VCF::LinuxFileStream::seek (  const uint64 &  offset, const SeekType &  offsetFrom )  [virtual]

moves the seek pointer offset number of bytes in the direction specified by the offsetFrom argument. Parameters: uint32  the number of bytes of offset the seek pointer SeekType  the direction to offset the seek pointer, which may be one of the following values SEEK_FROM_START - offsets from the beginning of the file SEEK_FROM_RELATIVE - offsets relative to the current seek position SEEK_FROM_END - offsets backwards, starting at the end of the file Implements VCF::FileStreamPeer.

virtual uint64 VCF::LinuxFileStream::write (  const unsigned char *  bytesToWrite, uint64  sizeOfBytes )  [virtual]

writes sizeOfBytes bytes to the file stream from the buffer bytesToWrite. Parameters: char*  a buffer that must be at least sizeOfBytes long, that contains the data that will written out to the file stream @  uint32 the number of bytes to write Implements VCF::FileStreamPeer.
