◆ handleCanPullPacketChanged()

void inet::EligibilityTimeGate::handleCanPullPacketChanged ( cGate * gate )

overridevirtual

Notifies about a change in the possibility of pulling some packet from the passive packet source at the given gate.

This method is called, for example, when a new packet is inserted into a queue. It allows the sink to pull a new packet from the queue.

The gate parameter must be a valid gate of this module.

◆ pullPacket()

Packet * inet::EligibilityTimeGate::pullPacket ( cGate * gate )

overridevirtual

Pulls the packet from the packet source at the given gate.

This operation pulls the packet as a whole. The onwership of the packet is transferred to the sink.

The source must not be empty at the given gate. The returned packet must not be nullptr. The gate must be a valid gate of this module and it must support pulling and passing packets.
