Detailed Description

template<typename Model>
template<typename DataType>
class uma::bson::ODMObject< Model >::MetaFieldImpl< DataType >

Encapsulates a field in a model object. Fields are represented as a triplet of the field in the class, and its accessor and mutator methods.

Template Parameters

Model	The type of the class whose field is to be represented. This is implied by the template parameter for the wrapper ODMObject class.
DataType	The data type for the field. Must be a sub-class of uma::bson::Value.
