de.esoco.j2me.model.MutableHierarchyNode

Extended Interface for node objects in a hierarchical data set which can be modified. It provides set methods for the data fields as well as methods to create, insert, and remove child nodes.

Because implementations that are edited interactively through an application should store their data immediately after editing according to the standard usage of J2ME devices, all modifing methods declare a StorageException so that access to an underlying HierarchicalStorage implementation can signal problems while accessing the storage.
