template<class TYPE >

StatusCode Service::setProperty	(	const std::string &	name,

set the property form the value

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

std::map<std::string,double> cuts = ... ;
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 convenient 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
