Uses of DataContext in org.apache.metamodel

Subinterfaces of DataContext in org.apache.metamodel

Modifier and Type	Interface and Description
interface	UpdateableDataContext Represents a DataContext that supports updating write-operations.

Classes in org.apache.metamodel that implement DataContext

Modifier and Type	Class and Description
class	AbstractDataContext Abstract implementation of the DataContext interface.
