Class JDBCSessionIdManager.DatabaseAdaptor

java.lang.Object

org.eclipse.jetty.server.session.JDBCSessionIdManager.DatabaseAdaptor

Enclosing class:

JDBCSessionIdManager

public static class JDBCSessionIdManager.DatabaseAdaptor
extends java.lang.Object

DatabaseAdaptor Handles differences between databases. Postgres uses the getBytes and setBinaryStream methods to access a "bytea" datatype, which can be up to 1Gb of binary data. MySQL is happy to use the "blob" type and getBlob() methods instead. TODO if the differences become more major it would be worthwhile refactoring this class.
