Class type Hydro_proxy.pool_t

class type pool_t = object .. end

A pool keeps connections from clients to servers

method set_esys : Unixqueue.event_system -> unit

Tell the pool the event system. Can only be done once

method request_clients : Hydro_types.system ->
       shared_or_private ->
       int ->
       (Hydro_connector.client_connector * Hydro_types.client_params) list ->
       managed_client_t list

Request clients from the pool

method deactivate_host : Unix.inet_addr -> float -> unit

Deactivate the host for this number of seconds

method deactivate_port : Hydro_types.network_port -> float -> unit

Deactivate the port for this number of seconds

method trigger_shutdown : unit -> unit

Shuts all pooled clients down. Note that this is an asynchronous shutdown, i.e. the shutdown actions are performed first when the event system is run!

After the shutdown, the pool is still usable, and new connections can again be created.

method shutdown : unit -> unit

Shuts all pooled clients down. This version is synchronous, and runs the event queue until all clients are down.

Note that it is possible that other pending events will cause attempts to create new connections while the shutdown is in progress. The pool revokes such attempts, such that it is ensured that all connections are down when this method returns.

After the shutdown, the pool is still usable, and new connections can again be created.

method abort : unit -> unit

Aborts all pooled clients (immediately)

method reset : unit -> unit

Shuts all clients down, and forget any deactivations

method is_available : Unix.inet_addr ->
       Hydro_types.network_port option ->
       shared_or_private -> float -> bool

This method is called by the pool implementation to check for the availability of a service. It is exposed in the public interface so it can be overridden by specialized pool implementations.
