Detailed Description

The useful base class for data processing algorithms.

Small extension of ordinary the Algorithm base class.

This base class allows "easy"(=="1 line") access to tools and services. This access is safe in the sense that there is no need to worry about the reference counts for tools and services.

The base class allows "easy" (=="1 line") access to data in Gaudi Transient Stores. The functionality includes the checking of the presence of the data at the given location, checking the validity of the data, retrieval of valid data and "forced" retrieve of valid data (create if there is no data).

The base class allows to perform an easy error, warning and exception treatments, including the accumulated statistics of exceptions, errors and warnings.

The base class also includes utilities for general statistical counters.

It has been reported that usage of this base class results in significant shrinkage of existing code lines.

Attention: See also the class GaudiCommon, which implements some of the common functionality between GaudiTool and GaudiAlgorithm.
