Detailed Description

reads from a seismic data store.

If you don't want all of the stored data, you must set use the SeisTrcTranslator facilities (SelData and ComponentData) after calling prepareWork(). If you don't call prepareWork(), the reader will do that but you cannot use SeisTrcTranslator facilities then.

Then, the routine is: get(trc.info()) possibly followed by get(trc). Not keeping this sequence is at your own risk.

Note: 2D Prestack data cannot (yet) be read via this class.

◆ get() [1/2]

bool SeisTrcReader::get ( SeisTrc & )

It is possible to directly call this without checking the get(SeisTrcInfo&) result. Beware that the trace selections in the SelData may be ignored then - depending on the Translator's capabilities.

◆ get() [2/2]

int SeisTrcReader::get ( SeisTrcInfo & )

-1 = Error. errMsg() will return a message. 0 = End 1 = Usable info 2 = Not usable (trace needs to be skipped) If 1 is returned, then you should also call get(SeisTrc&).
