Method Detail

connectInternal

protected void connectInternal()
Description copied from class: AbstractDatabaseManager
Implementations should implement this method to perform any proprietary connection operations. This method will never be called twice on the same instance. It is safe to throw any exceptions from this method.

Specified by:
connectInternal in class AbstractDatabaseManager

disconnectInternal

protected void disconnectInternal()
Description copied from class: AbstractDatabaseManager
Implementations should implement this method to perform any proprietary disconnection / shutdown operations. This method will never be called twice on the same instance, and it will only be called after AbstractDatabaseManager.connectInternal(). It is safe to throw any exceptions from this method.

Specified by:
disconnectInternal in class AbstractDatabaseManager

writeInternal

protected void writeInternal(LogEvent event)
Description copied from class: AbstractDatabaseManager
Performs the actual writing of the event in an implementation-specific way. This method is called immediately from AbstractDatabaseManager.write(LogEvent) if buffering is off, or from AbstractDatabaseManager.flush() if the buffer has reached its limit.

Specified by:
writeInternal in class AbstractDatabaseManager
Parameters:
event - The event to write to the database.

getJDBCDatabaseManager

public static JDBCDatabaseManager getJDBCDatabaseManager(String name,
                                                         int bufferSize,
                                                         ConnectionSource connectionSource,
                                                         String tableName,
                                                         ColumnConfig[] columnConfigs)
Creates a JDBC manager for use within the JDBCAppender, or returns a suitable one if it already exists.

Parameters:
name - The name of the manager, which should include connection details and hashed passwords where possible.
bufferSize - The size of the log event buffer.
connectionSource - The source for connections to the database.
tableName - The name of the database table to insert log events into.
columnConfigs - Configuration information about the log table columns.
Returns:
a new or existing JDBC manager as applicable.
