Detailed Description

Singleton buffer class for BMN raw data.

Date

19.12.2018

This class manages and provides access to buffers of type BmnMCPointBuffer - one for each detector.

The BmnDaqBuffer stores and sorts (w.r.t. time) BMN raw data (currently: BmnDigi) transiently. Data can be send to the buffer by the method InsertData. They can be retrieved by GetNextData, which delivers a time-ordered sequence of raw data objects for each detector.

The buffer handles objects only by pointer, i.e. the data have to be instantiated by the sending task (digitiser) and deleted by the receiving class (BmnDaq).
