bool | copyDatagram (SubfileInfo result, const Filename filename) |
Copies the file data from the entire indicated file (via the vfs) as the next datagram. More... | |
bool | copyDatagram (SubfileInfo result, const SubfileInfo source) |

const FileReference | getFile () |
Returns the FileReference that provides the target for these datagrams, if any, or NULL if the datagrams do not written to a file on disk. More... | |
const Filename | getFilename () |
Returns the filename that provides the target for these datagrams, if any, or empty string if the datagrams do not get written to a file on disk. More... | |
Streamoff | getFilePos () |
Returns the current file position within the data stream, if any, or 0 if the file position is not meaningful or cannot be determined. More... | |

const FileReference | file |

bool copyDatagram | ( | SubfileInfo | result, |
const Filename | filename | ||
) |
Copies the file data from the entire indicated file (via the vfs) as the next datagram.
This is intended to support potentially very large datagrams.
Returns true on success, false on failure or if this method is unimplemented. On true, fills "result" with the information that references the copied file, if possible.
bool copyDatagram | ( | SubfileInfo | result, |
const SubfileInfo | source | ||
) |
Copies the file data from the range of the indicated file (outside of the vfs) as the next datagram.
This is intended to support potentially very large datagrams.
Returns true on success, false on failure or if this method is unimplemented. On true, fills "result" with the information that references the copied file, if possible.
flush | ( | ) |
const FileReference getFile | ( | ) |
Returns the FileReference that provides the target for these datagrams, if any, or NULL if the datagrams do not written to a file on disk.
const Filename getFilename | ( | ) |
Returns the filename that provides the target for these datagrams, if any, or empty string if the datagrams do not get written to a file on disk.
Streamoff getFilePos | ( | ) |
Returns the current file position within the data stream, if any, or 0 if the file position is not meaningful or cannot be determined.
For DatagramSinks that return a meaningful file position, this will be pointing to the first byte following the datagram returned after a call to put_datagram().
bool isError | ( | ) |
bool putDatagram | ( | const Datagram | data | ) |
const FileReference file |
Returns the FileReference that provides the target for these datagrams, if any, or NULL if the datagrams do not written to a file on disk.
Streamoff file_pos |
Returns the current file position within the data stream, if any, or 0 if the file position is not meaningful or cannot be determined.
For DatagramSinks that return a meaningful file position, this will be pointing to the first byte following the datagram returned after a call to put_datagram().
const Filename filename |
Returns the filename that provides the target for these datagrams, if any, or empty string if the datagrams do not get written to a file on disk.
