Member Function Documentation

QVersitWriter::QVersitWriter ()

Constructs a new writer.

QVersitWriter::QVersitWriter ( QIODevice * outputDevice )

Constructs a new writer that writes to outputDevice.

QVersitWriter::QVersitWriter ( QByteArray * outputBytes )

Constructs a new writer that appends to outputBytes.

QVersitWriter::~QVersitWriter ()

Frees the memory used by the writer. Waits until a pending asynchronous writing has been completed.

void QVersitWriter::cancel () [slot]

Attempts to asynchronously cancel the write request.

QTextCodec * QVersitWriter::defaultCodec () const

Returns the document's codec.

See also setDefaultCodec().

QIODevice * QVersitWriter::device () const

Returns the device used for writing, or 0 if no device has been set.

See also setDevice().

Error QVersitWriter::error () const

Returns the error encountered by the last operation.

void QVersitWriter::setDefaultCodec ( QTextCodec * codec )

Sets the default codec for the writer to use for writing the entire output.

If codec is NULL, the writer uses the codec according to the specification prescribed default. (for vCard 2.1, ASCII; for vCard 3.0, UTF-8).

See also defaultCodec().

void QVersitWriter::setDevice ( QIODevice * device )

Sets the device used for writing to device. Does not take ownership of the device.

See also device().

bool QVersitWriter::startWriting ( const QList<QVersitDocument> & input ) [slot]

Starts writing input to device() asynchronously. The serialization format is determined based on the contents of the input documents.

Returns false if the output device has not been set or opened or if there is another asynchronous write operation already pending. Signal stateChanged() is emitted with parameter FinishedState when the writing has finished.

The device must be already open. The client is responsible for closing it when finished.

bool QVersitWriter::startWriting ( const QList<QVersitDocument> & input, QVersitDocument::VersitType type ) [slot]

Starts writing input to device() asynchronously using the serialization format specified by type. If type is QVersitDocument::InvalidType, the format will be determined based on the contents of the input documents.

Returns false if the output device has not been set or opened or if there is another asynchronous write operation already pending. Signal stateChanged() is emitted with parameter FinishedState when the writing has finished.

The device must be already open. The client is responsible for closing it when finished.

bool QVersitWriter::startWriting ( const QVersitDocument & input ) [slot]

Starts writing input to device() asynchronously. The serialization format is determined based on the contents of the input documents.

Returns false if the output device has not been set or opened or if there is another asynchronous write operation already pending. Signal stateChanged() is emitted with parameter FinishedState when the writing has finished.

The device must be already open. The client is responsible for closing it when finished.

bool QVersitWriter::startWriting ( const QVersitDocument & input, QVersitDocument::VersitType type ) [slot]

Starts writing input to device() asynchronously using the serialization format specified by type. If type is QVersitDocument::InvalidType, the format will be determined based on the contents of the input documents.

Returns false if the output device has not been set or opened or if there is another asynchronous write operation already pending. Signal stateChanged() is emitted with parameter FinishedState when the writing has finished.

The device must be already open. The client is responsible for closing it when finished.

State QVersitWriter::state () const

Returns the state of the writer.

void QVersitWriter::stateChanged ( QVersitWriter::State state ) [signal]

The signal is emitted by the writer when its state has changed (eg. when it has finished writing to the device). state is the new state of the writer.

bool QVersitWriter::waitForFinished ( int msec = -1 )

If the state is ActiveState, blocks until the writer has finished writing or msec milliseconds has elapsed, returning true if it successfully finishes or is cancelled by the user. If msec is negative or zero, the function blocks until the writer has finished, regardless of how long it takes. If the state is FinishedState, returns true immediately. Otherwise, returns false immediately.
