All Implemented Interfaces

org.hsqldb.persist.RandomAccessInterface

Imports

java.io.IOException, org.hsqldb.Database

Mixed NIO / non-NIO version of ScaledRAFile. This class is used only for storing a CACHED TABLE .data file and cannot be used for TEXT TABLE source files. Due to various issues with java.nio classes, this class will use a mapped channel of fixed size. After reaching this size, the file and channel are closed and a new one opened, up to the maximum size.
