Examples of InMemoryNodeModel

org.apache.commons.configuration.tree.InMemoryNodeModel

A specialized node model implementation which operates on {@link ImmutableNode} structures.

This {@code NodeModel} implementation keeps all its data as a tree of{@link ImmutableNode} objects in memory. The managed structure can bemanipulated in a thread-safe, non-blocking way. This is achieved by using atomic variables: The root of the tree is stored in an atomic reference variable. Each update operation causes a new structure to be constructed (which reuses as much from the original structure as possible). The old root node is then replaced by the new one using an atomic compare-and-set operation. If this fails, the manipulation has to be done anew on the updated structure.
