Interface Scope

All Known Implementing Classes:
GenericScope.Branch, GenericScope.Tree
public interface Scope

The scope describes a set of nodes, the scope implementation should be stateless and should be shared between many threads.

A scope is responsible for providing a Scope.Visitor object that is used to determine which nodes are loaded when a loading operation occurs. Visitors are not thread safe, as a consequence the get() operation should create a new visitor instance on each call, unless the visitor itself is stateless by nature.
