Package org.apache.activemq.store.jdbc.adapter

Class DefaultJDBCAdapter

java.lang.Object

org.apache.activemq.store.jdbc.adapter.DefaultJDBCAdapter

All Implemented Interfaces:

JDBCAdapter

Direct Known Subclasses:

BlobJDBCAdapter, BytesJDBCAdapter, DB2JDBCAdapter, ImageBasedJDBCAdaptor, MaxDBJDBCAdapter, MySqlJDBCAdapter, OracleJDBCAdapter, SqlServerJDBCAdapter, StreamJDBCAdapter

public class DefaultJDBCAdapter
extends Object
implements JDBCAdapter

Implements all the default JDBC operations that are used by the JDBCPersistenceAdapter.

sub-classing is encouraged to override the default implementation of methods to account for differences in JDBC Driver implementations.

The JDBCAdapter inserts and extracts BLOB data using the getBytes()/setBytes() operations.

The databases/JDBC drivers that use this adapter are:
