Member Function Documentation

bool FileSink::canWrite (  unsigned int  sec, unsigned int  usec )  throw ( Exception ) [virtual]

Check if the FileSink is ready to accept data. Blocks until the specified time for data to be available. Parameters: sec  the maximum seconds to block. usec  micro seconds to block after the full seconds. Returns: true if the Sink is ready to accept data, false otherwise. Exceptions: Exception  Implements Sink. Definition at line 241 of file FileSink.cpp. Referenced by FileCast::canWrite().

void FileSink::close (  void   )  throw ( Exception ) [virtual]

Close the FileSink. Exceptions: Exception  Implements Sink. Definition at line 298 of file FileSink.cpp. References fileDescriptor, flush(), and isOpen(). Referenced by FileCast::close(), and create().

bool FileSink::create (  void   )  throw ( Exception ) [virtual]

Create the file. Returns: true if creation was successful, false otherwise. Exceptions: Exception  Definition at line 200 of file FileSink.cpp. References close(), isOpen(), and Reporter::reportEvent().

bool FileSink::exists (  void   )  const throw () [virtual]

Check for the existence of the file this FileSink represents. Returns: true if the file exists and is a regular file, false otherwise. Definition at line 184 of file FileSink.cpp.

virtual void FileSink::flush (  void   )  throw ( Exception ) [inline, virtual]

This is a no-op in this FileSink. Exceptions: Exception  Implements Sink. Definition at line 226 of file FileSink.h. Referenced by close(), and FileCast::flush().

const char* FileSink::getFileName (  void   )  const throw () [inline]

Get the file name this FileSink represents. Returns: the file name this FileSink represents. Definition at line 152 of file FileSink.h.

virtual bool FileSink::isOpen (  void   )  const throw () [inline, virtual]

Check if the FileSink is open. Returns: true if the FileSink is open, false otherwise. Implements Sink. Definition at line 190 of file FileSink.h. References fileDescriptor. Referenced by close(), create(), FileCast::isOpen(), and open().

bool FileSink::open (  void   )  throw ( Exception ) [virtual]

Open the file. Truncates the file. Returns: true if opening was successful, false otherwise. Exceptions: Exception  Implements Sink. Definition at line 222 of file FileSink.cpp. References fileDescriptor, and isOpen().

FileSink & FileSink::operator= (  const FileSink &  fs  )  throw ( Exception ) [virtual]

Assignment operator. Parameters: fs  the FileSink to assign to this object. Returns: a reference to this object. Exceptions: Exception  Definition at line 154 of file FileSink.cpp. References Sink::operator=().

unsigned int FileSink::write (  const void *  buf, unsigned int  len )  throw ( Exception ) [virtual]

Write data to the FileSink. Parameters: buf  the data to write. len  number of bytes to write from buf. Returns: the number of bytes written (may be less than len). Exceptions: Exception  Implements Sink. Definition at line 271 of file FileSink.cpp. Referenced by FileCast::write().
