TriggerAdapter

An adapter for the trigger interface that allows to use the ResultSet interface instead of a row array.

Methods
void fire(Connection conn, Object[] oldRow, Object[] newRow)
void fire(Connection conn, Object[] oldRow, Object[] newRow) throws SQLException
void fire(Connection conn, ResultSet oldRow, ResultSet newRow)
This method is called for each triggered action by the default fire(Connection conn, Object[] oldRow, Object[] newRow) method.
void fire(Connection conn, ResultSet oldRow, ResultSet newRow) throws SQLException
This method is called for each triggered action by the default fire(Connection conn, Object[] oldRow, Object[] newRow) method.

For "before" triggers, the new values of the new row may be changed using the ResultSet.updateX methods.

Parameters:
conn - a connection to the database
oldRow - the old row, or null if no old row is available (for INSERT)
newRow - the new row, or null if no new row is available (for DELETE)
Throws:
SQLException - if the operation must be undone
void init(Connection conn, String schemaName, String triggerName, String tableName, boolean before, int type)
This method is called by the database engine once when initializing the trigger.
void init(Connection conn, String schemaName, String triggerName, String tableName, boolean before, int type) throws SQLException
This method is called by the database engine once when initializing the trigger. It is called when the trigger is created, as well as when the database is opened. The default implementation initialized the result sets.
Parameters:
conn - a connection to the database
schemaName - the name of the schema
triggerName - the name of the trigger used in the CREATE TRIGGER statement
tableName - the name of the table
before - whether the fire method is called before or after the operation is performed
type - the operation type: INSERT, UPDATE, DELETE, SELECT, or a combination (this parameter is a bit field)
