Examples of org.hsqldb_voltpatches.index.NodeAVLMemoryPointer

org.hsqldb_voltpatches.index.NodeAVLMemoryPointer
Text table node implementation.
Nodes for the AVL tree are all built and kept in memory while the actual row data is accessed via TextCache from disk.
This differs from MemoryNode by maintaining an integral pointer for the Row data instead of a Java reference. New class derived from Hypersonic SQL code and enhanced in HSQLDB.
