## 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.

bool GaudiAlgorithm::exist | ( | IDataProviderSvc * | svc,
|  | const std::string & | location,
|  | const bool | useRootInTES = `true`

Check the existence of a data object or container in the Gaudi Transient Event Store.

bool a1 = exist<DataObject>( evtSvc(), "/Event/MyObject" ) ;
bool a2 = exist<MyHits> ( evtSvc(), "/Event/MyHits" ) ;

Attention
  The method respects the setting of the job option RootInTES by prepending the value of this to the data location that is passed. The default setting for RootInTES is "" so has no effect. This behavior can be suppressed by passing the argument useRootInTES = false

Parameters

  svc | Pointer to data service (data provider)
  location | Address in Gaudi Transient Event Store
  useRootInTES | Flag to turn on(TRUE) off(FALSE) the use of the RootInTES location property

Returns
  Boolean indicating status of the request
