Detailed Description

Base class for all conversion services.

It manages a set of Converters that are specialized for conversions of specific objects.

This supports self learning converters: User hooks include the following (overridable) entries:

findCnvFactory: returns a suitable converter factory
createConverter: the actual convetrer creation
configureConverter: configure converter before initialize
initializeConverter: initializes the converter
activateConverter: any additional configuration to be done after initialize.

configureConverter and activateConverter are user hooks, where the convetrer can be manipulated by the hosting service and knowledge can be supplied, which a "generic" converter cannot aquire itself.

These hooks allow any sub-classed conversion service to override the calls and create converters, which aquire the knowledge about their persistency type and the object type they convert during the initialization.

Only AFTER these three steps the converter must satisfy the storage type of the hosting service and the class type of the required object type.
