org.apache.derby.impl.sql.execute.InternalTriggerExecutionContext
There is one of these beasts per INSERT/DELETE/UPDATE statement. It fulfills the contract for the externally visible trigger execution context and it validates that a statement that is about to be executed doesn't violate the restrictions placed upon what can be executed from a trigger.
Note that it is crucial that cleanup() is called once the DML has completed, cleanup() makes sure that users can't do something invalid on a tec reference that they were holding from when the trigger fired.

    int size = triggerExecutionContexts.size();
    //    System.out.println(" searching for " + aiKey);
    for (int i = size - 1; i >= 0; i--)
    {
      // first loop through triggers.
      InternalTriggerExecutionContext itec = 
        (InternalTriggerExecutionContext)triggerExecutionContexts.get(i);
      Long value = itec.getAutoincrementValue(aiKey);
      if (value == null)
        continue;


      return value;
