| 68 | * This class holds an Activation, and passes through most of the calls |
| 69 | * to the activation. The purpose of this class is to allow a PreparedStatement |
| 70 | * to be recompiled without the caller having to detect this and get a new |
| 71 | * activation. |
| 72 | * |
| 73 | * In addition to the Activation, this class holds a reference to the |
| 74 | * PreparedStatement that created it, along with a reference to the |
| 75 | * GeneratedClass that was associated with the PreparedStatement at the time |
| 76 | * this holder was created. These references are used to validate the |
| 77 | * Activation, to ensure that an activation is used only with the |
| 78 | * PreparedStatement that created it, and to detect when recompilation has |
| 79 | * happened. |
| 80 | * |
| 81 | * We detect recompilation by checking whether the GeneratedClass has changed. |
| 82 | * If it has, we try to let the caller continue to use this ActivationHolder. |
| 83 | * We create a new instance of the new GeneratedClass (that is, we create a |
| 84 | * new Activation), and we compare the number and type of parameters. If these |
| 85 | * are compatible, we copy the parameters from the old to the new Activation. |
| 86 | * If they are not compatible, we throw an exception telling the user that |
| 87 | * the Activation is out of date, and they need to get a new one. |
