Examples of RowAVLDisk

org.hsqldb.RowAVLDisk
In-memory representation of a disk-based database row object with methods for serialization and de-serialization.
A CachedRow is normally part of a circular double linked list which contains all of the Rows currently in the Cache for the database. It is unlinked from this list when it is freed from the Cache to make way for other rows.
New class derived from Hypersonic SQL code and enhanced in HSQLDB.
