Examples of org.hsqldb.index.IndexAVL

org.hsqldb.index.IndexAVL
Implementation of an AVL tree with parent pointers in nodes. Subclasses of Node implement the tree node objects for memory or disk storage. An Index has a root Node that is linked with other nodes using Java Object references or file pointers, depending on Node implementation.
An Index object also holds information on table columns (in the form of int indexes) that are covered by it.
New class derived from Hypersonic SQL code and enhanced in HSQLDB.
