Detailed Description

template<typename K, typename T, typename P, const char * F, bool D>
class dd::Entity_element< K, T, P, F, D >

Class to wrap an entity object.

The Entity_element instances are intended used in registries to support classification of meta data. The Entity_element template points to an instance of some type, and also has a property member that is associated with the entity, as well as a key with which the object is associated.

Note

The entity object ownership is decided by the relevant template parameter, see below.

Template Parameters

K	A key type, e.g. a pair of strings.
T	An entity type, e.g. an Object_table instance.
P	A property type, e.g. an enumeration.
F	Function to map from property to name.
D	Boolean to decide ownership of wrapped object.
