Domain object model (metadata) - in-memory representation of all *.meta files included in the application config. Developer should never create UBDomain class directly, but instead use a:
- App.domainInfo property inside server-side methods
- SyncConnection.getDomainInfo method inside CLI scripts
UBConnection.domain
property inside a browser
// server-side example
const UB = require('@unitybase/ub')
const App = UB.App
let ubaAuditPresent = App.domainInfo.has('uba_audit')
# new UBDomain (domainInfo: object)
Members
# dialectsPriority static
Priority to apply a mapping of a attributes/entities to the physical tables depending on connection dialect

# connections : Array.<DBConnectionConfig> instance
Connection collection (extended domain only)
# customerModels : Array.<string> instance
Array of customer models names
# defaultConnection : DBConnectionConfig instance
Default connection (extended domain only)
# entities : Object.<string, UBEntity> instance
Map with keys is entity name, value is UBEntity

Methods
# getPhysicalDataType (dataType: string) → string static
Return physical type by UBDataType
Arguments:
dataType
: string
# eachEntity (cb: domainEntitiesIteratorCallback) → object instance
Iterates over domain entities and invokes callBack
for each entity.
The iteratee is invoked with three arguments: (UBEntity, entityName, UBDomain.entities)
Arguments:
# filterEntities (predicate: object) → Array.<UBEntity> instance
Filter entities by properties
// sessionCachedEntities contains all entities with property cacheType === Session
var sessionCachedEntities = domain.filterEntities({cacheType: 'Session'});
# get (entityCode: string, raiseErrorIfNotExistsopt: boolean) → UBEntity instance
Get entity by code
# has (entityCode: string) → boolean instance
Check entity present in domain & user has access right for at least one entity method
Arguments:
entityCode
: string
# isEntityMethodsAccessible (entityCode: string, methodNames: string) → boolean instance
Check all provided entity methods are accessible via ELS.
If entity does not exist in domain or at last one of provided methods is not accessible - return false
