Detailed Description

template<typename KeyType, typename DataType, typename ObjectIdentificationTag, typename KeyDispatchTag, typename StorageTag>
struct viennadata::traits::container_erasure_dispatcher< KeyType, DataType, ObjectIdentificationTag, KeyDispatchTag, StorageTag >

A dispatch facility that unwraps type-erasued key-value type pairs.

Refer to Alexandrescu, "Modern C++ Design" for details on type erasure

Template Parameters:

	KeyType	The type of the key used for access
	DataType	Type of the data that is stored for the element
	ObjectType	The type of the object the data is associated with
	ObjectIdentificationTag	Determines the dispatch mechanism for objects the data is associated with. Either 'pointer_based_id' (the default) or 'object_provided_id' (requires suitable overload of 'object_identifier')
	KeyDispatchTag	Determines the method for key dispatch (either full dispatch ('full_KeyDispatchTag', default) or dispatch based on key type 'type_KeyDispatchTag')
	StorageTag	Specifies dense ('dense_data_tag') or sparse ('storage_data_tag', default) storage of data. The former requires element-identification by id, cf. class 'object_identifier'
