Deregisters itself at the consumers.
Member Function Documentation
| void NSCore::DataSetProducer::registerConsumer | ( | DataSetChainMember * | ) |
Register a consumer.
This registers a DataSetChainMember as this objects consumer.
The emitted data is sent to all consumers via the (internal) DataSetEvent through Qt's event system.
| void NSCore::DataSetProducer::unregisterConsumer | ( | DataSetChainMember * | ) |
Unregister a consumer.
| void NSCore::DataSetProducer::unregisterAllConsumers | ( | ) |
Unregister all consumers.
| void NSCore::DataSetProducer::setDispatching | ( | Dispatching | ) |
| int NSCore::DataSetProducer::consumersSize | ( | ) | const |
Return the number of registered consumers.
This way a producer can decide not to do expensive conversions and similar stuff when there is no consumer to actually use the data.
| bool NSCore::DataSetProducer::consumersIsEmpty | ( | ) | const |
Return wether there are consumers or not.
Even simplier then consumersSize().

| void NSCore::DataSetProducer::countsPerSecond | ( | double | ) | [signal] |
Speed-o-meter.
The enqueue()-function tries to keep track on how many datasets where sent to the next chain-member and will emit this signal at (ir-)regular intervals.
| void NSCore::DataSetProducer::enqueue | ( | AcqisitionDataSet & | ) | [protected] |
Add data to the queue.
The data is sent to all registered consumers via Qt' event system.
