The CScaler class is an abstract base class for
high level support for scaler modules that append data into an STL vector.
The interfaces defined by this class are suitable for use with scaler classes
in the production readout skeleton.
Since CScaler is an abstract base class this documentation
will only describe the expectations that must be met by concrete derived classes.
This function is expected to perform pre-start initialization. Once this function returns, the scaler managed by this object should be able to count given appropriate inputs.
Read is supposed to read all channels from the
scaler module controlled by this object and sequentially append them to the
vector Scalers. An STL vector is appended to by
invoking it's push_back() member.
This function is expected to clear all scaler channels. Note that
if Initialize and Read
both exit with the scaler counters cleared, this function can be
implemented as a no-op.
This function is no longer actually called but currently must be implemented. It used to return the number of scaler channels the object would read.
