A data source
inline explicit DataSource (const char* format = "slin")
| DataSource |
Source constructor
Parameters:
format | Name of the data format, default "slin" (Signed Linear) |
void destroyed ()
| destroyed |
[virtual]
Source's destruct notification - detaches all consumers
Reimplemented from RefObject.
void* getObject (const String& name)
| getObject |
[const virtual]
Get a pointer to a derived class given that class name
Parameters:
name | Name of the class we are asking for |
Returns: Pointer to the requested class or NULL if this object doesn't implement it
Reimplemented from RefObject.
bool valid ()
| valid |
[const virtual]
Check if this data source is still valid
Returns: True if still valid, false if node should be removed
Reimplemented from DataNode.
unsigned long Forward (const DataBlock& data, unsigned long tStamp = invalidStamp(),
unsigned long flags = 0)
| Forward |
Forwards the data to its consumers
Parameters:
data | The raw data block to forward |
tStamp | Timestamp of data - typically samples |
flags | Indicator flags associated with the data block |
Returns: Number of samples actually forwarded to all consumers
bool attach (DataConsumer* consumer, bool override = false)
| attach |
Attach a data consumer
Parameters:
consumer | Data consumer to attach |
override | Attach as temporary source override |
Returns: True on success, false on failure
bool detach (DataConsumer* consumer)
| detach |
Detach a data consumer
Parameters:
consumer | Data consumer to detach |
Returns: True on success, false on failure
void clear ()
| clear |
Detach all data consumers
inline DataTranslator* getTranslator ()
| getTranslator |
[const]
Get the master translator object if this source is part of a translator
Returns: A pointer to the DataTranslator object or NULL
void synchronize (unsigned long tStamp)
| synchronize |
Synchronize the source and attached consumers with another timestamp
Parameters:
tStamp | New timestamp of data - typically samples |
inline unsigned long nextStamp ()
| nextStamp |
[const]
Get the next expected position in the data stream
Returns: Timestamp of next expected data position, may be invalid/unknown
unsigned long m_nextStamp | m_nextStamp |
[protected]
ObjList m_consumers | m_consumers |
