Signals

void	connectedChanged()
void	dataAvailable(const QVariant &data)

Detailed Description

QInferenceBackendStep subclasses create a QInferenceBackendDataPort to represent input and output ports. It forwards data through the dataAvailable() signal when connectTo() links two ports.

See also QInferenceDataPort, QInferenceBackendStep, name(), type(), and connectTo().

Property Documentation

connected : bool

This property holds whether this port is connected to another port.

QInferenceDataPort::connectTo() sets the property on both ports it links.

Access functions:

bool	isConnected() const
void	setConnected(bool connected)

Notifier signal:

void	connectedChanged()

See also connectTo().

Member Function Documentation

`[explicit]` QInferenceBackendDataPort::QInferenceBackendDataPort(const QString &name, QInferenceDataPort::Type type, QObject **parent* = nullptr)

Constructs a QInferenceBackendDataPort with the given name, type, and parent.

`[virtual]` bool QInferenceBackendDataPort::connectTo(QInferenceBackendDataPort **other*)

Connects this port to other by forwarding dataAvailable() from this port to the other. Returns true on success.

See also dataAvailable.

`[signal]` void QInferenceBackendDataPort::dataAvailable(const QVariant &data)

This signal is emitted when data becomes available on this port.

See also connectTo().

QInferenceDataPort::Direction QInferenceBackendDataPort::direction() const

Returns the direction of this port (In or Out).

See also setDirection().

QString QInferenceBackendDataPort::name() const

Returns the name of this port.

See also type().

void QInferenceBackendDataPort::setDirection(QInferenceDataPort::Direction direction)

Sets the port direction to direction.

See also direction().

QInferenceDataPort::Type QInferenceBackendDataPort::type() const

Returns the data type of this port.

See also name().
