## Detailed Description

A data consumer

## Constructor & Destructor Documentation

DataConsumer | ( | const char * | format = `"slin"` | ) |
| inlineexplicit

Consumer constructor

Parameters

  format | Name of the data format, default "slin" (Signed Linear)

## Member Function Documentation

virtual unsigned long Consume | ( | const DataBlock & | data,
|  | unsigned long | tStamp,
|  | unsigned long | flags
| ) |  |
| pure virtual

Consumes the data sent to it from a source

Parameters

  data | The raw data block to process
  tStamp | Timestamp of data - typically samples
  flags | Indicator flags associated with the data block

Returns
  Number of samples actually consumed, use invalidStamp() to indicate that all data was consumed, return zero for consumers that become invalid

virtual void destroyed | ( |  | ) |
| virtual

Destruct notification - complains loudly if still attached to a source

Reimplemented from RefObject.

DataSource* getConnSource | ( |  | ) | const
| inline

Get the data source of this object if it's connected

Returns
  A pointer to the DataSource object or NULL

virtual void* getObject | ( | const String & | name | ) | 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.

Reimplemented in DataTranslator.

DataSource* getOverSource | ( |  | ) | const
| inline

Get the override data source of this object if it's connected

Returns
  A pointer to the DataSource object or NULL

virtual DataSource* getTransSource | ( |  | ) | const
| inlinevirtual

Get the data source of a translator object

Returns
  A pointer to the DataSource object or NULL

Reimplemented in DataTranslator.

virtual bool synchronize | ( | DataSource * | source | ) |
| protectedvirtual

Synchronize the consumer with a source

Parameters

  source | Data source to copy the timestamp from

Returns
  True if we could synchronize with the source

Reimplemented in DataTranslator.
