) | [inline, explicit] |
Source constructor
format | Name of the data format, default "slin" (Signed Linear) |
virtual void destroyed | ( | ) | [virtual] |
Source's destruct notification - detaches all consumers
Reimplemented from RefObject.
Reimplemented in ThreadedSource.
virtual void* getObject | ( | const String & | name | ) | const [virtual] |
Get a pointer to a derived class given that class name
name | Name of the class we are asking for |
Reimplemented from GenObject.
virtual bool valid | ( | ) | const [virtual] |
Check if this data source is still valid
Reimplemented from DataNode.
unsigned long Forward | ( | const DataBlock & | data, | |
unsigned long | tStamp = invalidStamp() , |
|||
unsigned long | flags = 0 | |||
) |
Forwards the data to its consumers
data | The raw data block to forward | |
tStamp | Timestamp of data - typically samples | |
flags | Indicator flags associated with the data block |
bool attach | ( | DataConsumer * | consumer, | |
bool | override = false | |||
) |
Attach a data consumer
consumer | Data consumer to attach | |
override | Attach as temporary source override |
bool detach | ( | DataConsumer * | consumer | ) |
Detach a data consumer
consumer | Data consumer to detach |
void clear | ( | ) |
Detach all data consumers
DataTranslator* getTranslator | ( | ) | const [inline] |
