Ice

Overview

module Ice

The Ice core library. Among many other features, the Ice core library manages all the communication tasks using an efficient protocol (including protocol compression and support for both TCP and UDP), provides a thread pool for multi-threaded servers, and additional functionality that supports high scalability.

Interface Index

Communicator: The central object in Ice.
Connection: The user-level interface to a connection.
Endpoint: The user-level interface to an endpoint.
ImplicitContext: An interface to associate implict contexts with communicators.
Locator: The Ice locator interface.
LocatorRegistry: The Ice locator registry interface.
Logger: The Ice message logger.
ObjectAdapter: The object adapter provides an up-call interface from the Ice run time to the implementation of Ice objects.
ObjectFactory: A factory for objects.
Plugin: A communicator plugin.
PluginManager: Each communicator has a plugin manager to administer the set of plugins.
Process: An administrative interface for process management.
Properties: A property set used to configure Ice and Ice applications.
PropertiesAdmin: The PropertiesAdmin interface provides remote access to the properties of a communicator.
Router: The Ice router interface.
ServantLocator: A servant locator is called by an object adapter to locate a servant that is not found in its active servant map.
Stats: An interface Ice uses to report statistics, such as how much data is sent or received.
