## Detailed Description

### template<class TYPE>
struct Gaudi::Utils::PropertyTypeTraits< TYPE >

helper structure to define the types for properties

For implementation of SimpleProperty<TYPE> one needs:

- "default constructor"
- "smart copy-constructor"
- "smart destructor"
- "assign"
- "less"

For implementation of SimplePropertyRef<TYPE> one needs:

- "copy constructor"
- "smart copy-constructor
- "smart destructor"
- "assign"
- "less"

For all cases one needs to have valid functions:

- StatusCode Gaudi::Parsers::parse ( TYPE& , const std::string& )
- std::ostream& Gaudi::Utils::toStream ( cost TYPE& , std::ostream& )
