PointerNode

class PointerNode extends BaseMemoryNode (Code)

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 based on Hypersonic SQL code.
