	GetExpensiveProperties(String)	Retrieves a list of expensive properties from the object store.
	GetExpensiveProperties(String, array<Object[])	Retrieves a list of expensive properties from the object store.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetMappings	Returns key/value pairs of mapped property names and their corresponding data source–specific property names.
	GetOrdering(String)	Returns the ordering for the specified type as a string of comma-delimited data object names, which specifies the sort order of the data objects returned when objects are selected.
	GetOrdering(String, array<Object[])	Returns the ordering for the specified type as a string of comma-delimited data object names, which specifies the sort order of the data objects returned when objects are selected.
	GetRequiredRestrictions(String)	Retrieves a list of the restrictions that are required when data objects are selected for the specified type.
	GetRequiredRestrictions(String, array<Object[])	Retrieves a list of the restrictions that are required when data objects are selected for the specified type.
	GetSupportedRestrictions(String)	Retrieves all the restrictions that are supported when data objects are selected for the specified type.
	GetSupportedRestrictions(String, array<Object[])	Retrieves all the restrictions that are supported when data objects are selected for the specified type.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnSiteChanged	Raises the SiteChanged event. (Inherited from DataSiteableObject<T>.)
	SelectObjects(String, array<Object[], array<String[])	Returns a data reader for the data objects retrieved from the object store, which are filtered by the specified restrictions and properties.
	SelectObjects(String, array<Object[], array<String[], array<Object[])	Returns a data reader for the data objects retrieved from the object store, which are filtered by the specified restrictions, properties, and parameters.
