## Detailed Description

Base class from which all the concrete tool classes should be derived.

Specific methods for doing something usefull should be implemented in the concrete tools. Sub-types of this class could implement an additional interface for behaviour common to sets of concrete tools (for example vertexers).

template<class TYPE>

StatusCode AlgTool::setProperty | ( | const std::string & | name,
|  | const TYPE & | value |
| ) |  |  | `[inline]`

set the property form the value

      std::vector<double> data = ... ;

      setProperty( "Cuts" , cuts ) ;

      std::map<std::string,std::string> dict = ... ;
      setProperty( "Dictionary" , dict ) ;

Note: the interface IProperty allows setting of the properties either directly from other properties or from strings only

This is very convinient in resetting of the default properties in the derived classes. E.g. without this method one needs to convert everything into strings to use IProperty::setProperty

        setProperty ( "OutputLevel" , "1"    ) ;
        setProperty ( "Enable"      , "True" ) ;
        setProperty ( "ErrorMax"    , "10"   ) ;

For simple cases it is more or less ok, but for complicated properties it is just ugly..

Parameters:

  | name | name of the property
  | value | value of the property
