Detailed Description

template<typename Model>
class uma::bson::ODMObject< Model >::MetaField

Abstract base class that encapsulates a field in a model object. Primarily used to get around requirement that implementation needs exact type of data encapsulated in the field as template type.

Template Parameters

Model

The type of the class whose field is to be represented

Constructor & Destructor Documentation

template<typename Model >

uma::bson::ODMObject< Model >::MetaField::MetaField ( const std::string &  field )

inline

Create a new instance representing the field with the specified name.

Parameters

field

The name of the field.

template<typename Model >

virtual uma::bson::ODMObject< Model >::MetaField::~MetaField ( )

inlinevirtual

Virtual dtor for sub-classing.

Member Function Documentation

template<typename Model >

const std::string& uma::bson::ODMObject< Model >::MetaField::getName ( ) const

inline

Return the name of the field encapsulated in this meta field instance.

Returns

const std::string The field name.

template<typename Model >

virtual Value& uma::bson::ODMObject< Model >::MetaField::getValue ( Model *  model )

pure virtual

Return the value for the field represented by this instance.

Parameters

model

The model object from which the value is to retrieved.

Returns

Value The value for the field.

Implemented in uma::bson::ODMObject< Model >::MetaFieldImpl< DataType >.

template<typename Model >

virtual void uma::bson::ODMObject< Model >::MetaField::setValue ( Model *  model, const Value &  value  )

pure virtual

Set the value for the field represented by this instance.

Parameters

model	The model object in which the value is to be stored.
value	The value for the field to store.

Implemented in uma::bson::ODMObject< Model >::MetaFieldImpl< DataType >.
