## Detailed Description

Base class from which all concrete algorithm classes should be derived.

In order for a concrete algorithm class to do anything useful the methods initialize(), execute() and finalize() should be overridden.

The base class provides utility methods for accessing standard services (event data service etc.); for declaring properties which may be configured by the job options service; and for creating sub algorithms. The only base class functionality which may be used in the constructor of a concrete algorithm is the declaration of member variables as properties. All other functionality, i.e. the use of services and the creation of sub-algorithms, may be used only in initialize() and afterwards (see the Gaudi user guide).

StatusCode Algorithm::createSubAlgorithm | ( | const std::string & | type,
|  | const std::string & | name,
|  | Algorithm *& | pSubAlg
| ) |  |

Create a sub algorithm.

A call to this method creates a child algorithm object. Note that the returned pointer is to Algorithm (as opposed to IAlgorithm), and thus the methods of IProperty are also available for the direct setting of the sub-algorithm's properties. Using this mechanism instead of creating daughter algorithms directly via the new operator is prefered since then the framework may take care of all of the necessary book-keeping.

Parameters

  type | The concrete algorithm class of the sub algorithm
  name | The name to be given to the sub algorithm
  pSubAlg | Set to point to the newly created algorithm object
