Ice::ServantLocator
Overview
local interface ServantLocator |
The servant locator, which is called by the object adapter to locate a servant that is not found in its active servant map.
Operation Index
- deactivate
Called when the object adapter in which this servant locator is installed is deactivated.
- finished
Called by the object adapter after a request has been made.
- locate
Called by the object adapter before a request is made when a servant cannot be found in the object adapter's active servant map.
deactivate
void deactivate(string category); |
Called when the object adapter in which this servant locator is installed is deactivated.
finished
void finished(Current curr, Object servant, LocalObject cookie); |
Called by the object adapter after a request has been made. This operation is only called if locate was called prior to the request and returned a non-null servant. This operation can be used for cleanup purposes after a request.
locate
Object locate(Current curr, out LocalObject cookie); |
Called by the object adapter before a request is made when a servant cannot be found in the object adapter's active servant map. Note that the object adapter does not automatically insert the returned servant into its active servant map. This must be done by the servant locator implementation, if this is desired.
 | If you call locate from your own code, you must also call finished when you have finished using the servant, provided that a non-null servant was returned. Otherwise you will get undefined behavior if you use Servant Locators such as the ::Freeze::Evictor. |
Parameters
- curr
Information about the current operation for which a servant is required.
- cookie
A "cookie" that will be passed to finished.
