Method Detail

fire

public void fire(int type,
                 java.lang.String trigName,
                 java.lang.String tabName,
                 java.lang.Object[] oldRow,
                 java.lang.Object[] newRow)

Description copied from interface: Trigger

The method invoked upon each triggered action.

type contains the integer index id for trigger type, e.g. TriggerDef.INSERT_AFTER

For all triggers defined as default FOR EACH STATEMENT both oldRow and newRow are null.

For triggers defined as FOR EACH ROW, the following will apply:

When UPDATE triggers are fired, oldRow contains the existing values of the table row and newRow contains the new values.

For INSERT triggers, oldRow is null and newRow contains the table row to be inserted. For DELETE triggers, newRow is null and oldRow contains the table row to be deleted.

For error conditions, users can construct an HsqlException using one of the static methods of org.hsqldb.error.Error with a predefined SQL State from org.hsqldb.error.ErrorCode.

Specified by:

fire in interface Trigger

Parameters:

type - the type as one of the int values defined in the interface

trigName - the name of the trigger

tabName - the name of the table upon which the triggered action is occuring

oldRow - the old row
