Class RAFileHybrid

java.lang.Object

org.hsqldb.persist.RAFileHybrid

All Implemented Interfaces:

RandomAccessInterface

public final class RAFileHybrid
extends java.lang.Object
implements RandomAccessInterface

Mixe 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.

Since:

1.7.2
