Detailed Description

Writes data to files on disc.

Member Typedef Documentation

◆ Ref

Type holding strong reference.

Constructor & Destructor Documentation

◆ decDiskFileWriter()

decDiskFileWriter::decDiskFileWriter ( const char *  filename,
bool  append 
)

Create file reader object for the file.

The file is opened immediatly for writing. The filename specified has to be an absolute path.

Exceptions
deeInvalidParamfilename is NULL.
deeFileNotFoundfilename can not be opened for writing.

◆ ~decDiskFileWriter()

virtual decDiskFileWriter::~decDiskFileWriter ( )
protectedvirtual

Close file and clean up.

Note
Subclasses should set their destructor protected too to avoid users accidently deleting a reference counted object through the object pointer. Only FreeReference() is allowed to delete the object.

Member Function Documentation

virtual decBaseFileWriter::Ref decDiskFileWriter::Duplicate ( )
virtual

Duplicate file writer.

Implements decBaseFileWriter.

Implements decBaseFileWriter.

◆ GetPosition()

virtual int decDiskFileWriter::GetPosition ( )
virtual

Implements decBaseFileWriter.

◆ MovePosition()

virtual void decDiskFileWriter::MovePosition ( int  offset)
virtual

Move file position by the given offset.

Implements decBaseFileWriter.

◆ SetPosition()

virtual void decDiskFileWriter::SetPosition ( int  position)
virtual

Set file position for the next write action.

Implements decBaseFileWriter.

◆ SetPositionEnd()

virtual void decDiskFileWriter::SetPositionEnd ( int  position)
virtual

Set file position to the given position measured from the end of the file.

Implements decBaseFileWriter.

◆ Write()

virtual void decDiskFileWriter::Write ( const void *  buffer,
int  size 
)
virtual

Write size bytes from buffer and advances the file pointer.

Exceptions
deeInvalidParambuffer is NULL.
deeInvalidParamsize is less than 0.
deeWriteFileCan not write to file.

Implements decBaseFileWriter.
