org.lilyproject.repository.api.RecordType
A record type describes the schema to be followed by a {@link Record}.
Record types are managed via the {@link TypeManager}. To instantiate a RecordType use {@link TypeManager#newRecordType(QName)} TypeManager.newRecordType}. As all entities within this API,record types are dumb data objects.
A record type consists of:
- a list of field types, associated via {@link FieldTypeEntry} which defines properties specific to the useof a field type within this record type.
- a list of supertypes, these are references to other record types that are parent types for this record type.
Record types are versioned: upon each update, a new version of the record type is created. Record store a pointer to the particular version of a record type that was used when creating/updating a record type. The references to the supertype record types are also to specific versions.
A record type has two unique identifiers:
- a system-generated id, immutable after creation of the record type
- a name in the form of a {@link QName qualified (namespaced) name}, which is mutable after creation of the record type. Changing the name of a record type affects all versions of the record type (the name is a non-versioned property of the record type).
