/** |
|
115 |
* The Activator facilitates remote object activation. A "faulting" |
|
116 |
* remote reference calls the activator's <code>activate</code> method |
|
117 |
* to obtain a "live" reference to a activatable remote object. Upon |
|
118 |
* receiving a request for activation, the activator looks up the |
|
119 |
* activation descriptor for the activation identifier, id, determines |
|
120 |
* the group in which the object should be activated and invokes the |
|
121 |
* activate method on the object's activation group (described by the |
|
122 |
* remote interface <code>ActivationInstantiator</code>). The |
|
123 |
* activator initiates the execution of activation groups as |
|
124 |
* necessary. For example, if an activation group for a specific group |
|
125 |
* identifier is not already executing, the activator will spawn a |
|
126 |
* child process for the activation group. <p> |
|
127 |
* |
|
128 |
* The activator is responsible for monitoring and detecting when |
|
129 |
* activation groups fail so that it can remove stale remote references |
|
130 |
* from its internal tables. <p> |
