getDataStoreNames

public Set<String> getDataStoreNames()

getDataModels

public Map<String,Map<String,DataModel>> getDataModels()

Retrieves an unmodifiable view of the internal data model storage. The returned map represents an organizational structure where the first-level keys are data store identifiers and the values are nested maps. The nested maps use entity names as keys and their corresponding DataModel objects as values.

Returns:

a map containing data store identifiers as keys, where each value is another map that maps entity names to their respective DataModel instances. The returned map is unmodifiable.

getDataModels

public Map<String,DataModel> getDataModels(String dataStore)

Retrieves the data models associated with a specific data store.

Parameters:

dataStore - the name of the data store whose data models are to be retrieved; must not be null

Returns:

a map where the keys are entity names and the values are the corresponding DataModel instances

isAnnotationPresent

protected boolean isAnnotationPresent(MetaProperty field,
 Class<? extends Annotation> annotationClass)

getAnnotation

protected <T extends Annotation> T getAnnotation(MetaProperty field,
 Class<T> annotationClass)

getElementTypeFromCollection

protected String getElementTypeFromCollection(MetaProperty metaProperty)
