Member Function Documentation

◆ addAdminFacet()

virtual void Ice::Communicator::addAdminFacet	(	const ObjectPtr &	servant,
		const ::std::string &	facet
	)

pure virtual

Add a new facet to the Admin object.

Adding a servant with a facet that is already registered throws AlreadyRegisteredException.

Parameters

servant	The servant that implements the new Admin facet.
facet	The name of the new Admin facet.

◆ addObjectFactory()

virtual void Ice::Communicator::addObjectFactory	(	const ObjectFactoryPtr &	factory,
		const ::std::string &	id
	)

pure virtual

Add an object factory to this communicator.

Installing a factory with an id for which a factory is already registered throws AlreadyRegisteredException.

When unmarshaling an Ice object, the Ice run time reads the most-derived type id off the wire and attempts to create an instance of the type using a factory. If no instance is created, either because no factory was found, or because all factories returned nil, the behavior of the Ice run time depends on the format with which the object was marshaled:

If the object uses the "sliced" format, Ice ascends the class hierarchy until it finds a type that is recognized by a factory, or it reaches the least-derived type. If no factory is found that can create an instance, the run time throws NoValueFactoryException.

If the object uses the "compact" format, Ice immediately raises NoValueFactoryException.

The following order is used to locate a factory for a type:

The Ice run-time looks for a factory registered specifically for the type.
If no instance has been created, the Ice run-time looks for the default factory, which is registered with an empty type id.
If no instance has been created by any of the preceding steps, the Ice run-time looks for a factory that may have been statically generated by the language mapping for non-abstract classes.

Parameters

factory	The factory to add.
id	The type id for which the factory can create instances, or an empty string for the default factory.

Deprecated:: addObjectFactory() is deprecated, use ValueFactoryManager::add() instead.

◆ begin_flushBatchRequests() [1/3]

virtual AsyncResultPtr Ice::Communicator::begin_flushBatchRequests ( CompressBatch compress )

pure virtual

Flush any pending batch requests for this communicator.

This means all batch requests invoked on fixed proxies for all connections associated with the communicator. Any errors that occur while flushing a connection are ignored.

Parameters

compress Specifies whether or not the queued batch requests should be compressed before being sent over the wire.

Returns: The asynchronous result object for the invocation.

◆ begin_flushBatchRequests() [2/3]

virtual AsyncResultPtr Ice::Communicator::begin_flushBatchRequests	(	CompressBatch	compress,
		const Callback_Communicator_flushBatchRequestsPtr &	cb,
		const LocalObjectPtr &	cookie = `0`
	)

pure virtual

Flush any pending batch requests for this communicator.

This means all batch requests invoked on fixed proxies for all connections associated with the communicator. Any errors that occur while flushing a connection are ignored.

Parameters

compress	Specifies whether or not the queued batch requests should be compressed before being sent over the wire.
cb	Callback to be invoked when the invocation completes
cookie	Extra data to associate with the invocation.

Returns: The asynchronous result object for the invocation.

◆ begin_flushBatchRequests() [3/3]

virtual AsyncResultPtr Ice::Communicator::begin_flushBatchRequests	(	CompressBatch	compress,
		const CallbackPtr &	cb,
		const LocalObjectPtr &	cookie = `0`
	)

pure virtual

Flush any pending batch requests for this communicator.

This means all batch requests invoked on fixed proxies for all connections associated with the communicator. Any errors that occur while flushing a connection are ignored.

Parameters

compress	Specifies whether or not the queued batch requests should be compressed before being sent over the wire.
cb	Callback to be invoked when the invocation completes

◆ createAdmin()

virtual ObjectPrx Ice::Communicator::createAdmin	(	const ObjectAdapterPtr &	adminAdapter,
		const Identity &	adminId
	)

pure virtual

Add the Admin object with all its facets to the provided object adapter.

If Ice.Admin.ServerId is set and the provided object adapter has a Locator, createAdmin registers the Admin's Process facet with the Locator's LocatorRegistry.

createAdmin must only be called once; subsequent calls raise InitializationException.

Parameters

adminAdapter	The object adapter used to host the Admin object; if null and Ice.Admin.Endpoints is set, create, activate and use the Ice.Admin object adapter.
adminId	The identity of the Admin object.

Returns: A proxy to the main ("") facet of the Admin object. Never returns a null proxy.

See also: getAdmin

◆ createObjectAdapter()

virtual ObjectAdapterPtr Ice::Communicator::createObjectAdapter ( const ::std::string & name )

pure virtual

Create a new object adapter.

The endpoints for the object adapter are taken from the property name.Endpoints.

It is legal to create an object adapter with the empty string as its name. Such an object adapter is accessible via bidirectional connections or by collocated invocations that originate from the same communicator as is used by the adapter.

Attempts to create a named object adapter for which no configuration can be found raise InitializationException.

Parameters

name	The object adapter name.

Returns: The new object adapter.

See also: createObjectAdapterWithEndpoints; ObjectAdapter; Properties

◆ createObjectAdapterWithEndpoints()

virtual ObjectAdapterPtr Ice::Communicator::createObjectAdapterWithEndpoints	(	const ::std::string &	name,
		const ::std::string &	endpoints
	)

pure virtual

Create a new object adapter with endpoints.

This operation sets the property name.Endpoints, and then calls createObjectAdapter. It is provided as a convenience function.

Calling this operation with an empty name will result in a UUID being generated for the name.

Parameters

name	The object adapter name.
endpoints	The endpoints for the object adapter.

Returns: The new object adapter.

Returns: The new object adapter.

See also: createObjectAdapter; ObjectAdapter; Properties

◆ destroy()

virtual void Ice::Communicator::destroy	(	)
throw	(
	)

pure virtual

Deprecated:: findObjectFactory() is deprecated, use ValueFactoryManager::find() instead.

◆ flushBatchRequests()

virtual void Ice::Communicator::flushBatchRequests ( CompressBatch compress )

pure virtual

Flush any pending batch requests for this communicator.

This means all batch requests invoked on fixed proxies for all connections associated with the communicator. Any errors that occur while flushing a connection are ignored.

Parameters

compress Specifies whether or not the queued batch requests should be compressed before being sent over the wire.

◆ getAdmin()

virtual ObjectPrx Ice::Communicator::getAdmin ( ) const

pure virtual

Get a proxy to the main facet of the Admin object.

getAdmin also creates the Admin object and creates and activates the Ice.Admin object adapter to host this Admin object if Ice.Admin.Enpoints is set. The identity of the Admin object created by getAdmin is {value of Ice.Admin.InstanceName}/admin, or {UUID}/admin when Ice.Admin.InstanceName is not set.

If Ice.Admin.DelayCreation is 0 or not set, getAdmin is called by the communicator initialization, after initialization of all plugins.

Returns: The servant associated with this Admin facet.

◆ setDefaultLocator()

virtual void Ice::Communicator::setDefaultLocator ( const LocatorPrx & loc )

pure virtual

Set a default Ice locator for this communicator.

All newly created proxy and object adapters will use this default locator. To disable the default locator, null can be used. Note that this operation has no effect on existing proxies or object adapters.

You can also set a locator for an individual proxy by calling the operation ice_locator on the proxy, or for an object adapter by calling ObjectAdapter#setLocator on the object adapter.

Parameters

loc	The default locator to use for this communicator.

See also: getDefaultLocator; Locator; ObjectAdapter::setLocator

◆ setDefaultRouter()

virtual void Ice::Communicator::setDefaultRouter ( const RouterPrx & rtr )

pure virtual

Set a default router for this communicator.

All newly created proxies will use this default router. To disable the default router, null can be used. Note that this operation has no effect on existing proxies.

You can also set a router for an individual proxy by calling the operation ice_router on the proxy.

Parameters

rtr	The default router to use for this communicator.

See also: getDefaultRouter; createObjectAdapterWithRouter; Router

◆ shutdown()

virtual void Ice::Communicator::shutdown	(	)
throw	(
	)

pure virtual

Shuts down this communicator's server functionality, which includes the deactivation of all object adapters.

Attempts to use a deactivated object adapter raise ObjectAdapterDeactivatedException. Subsequent calls to shutdown are ignored.

After shutdown returns, no new requests are processed. However, requests that have been started before shutdown was called might still be active. You can use waitForShutdown to wait for the completion of all requests.

See also: destroy; waitForShutdown; ObjectAdapter::deactivate

◆ stringToIdentity()

virtual Identity Ice::Communicator::stringToIdentity ( const ::std::string & str ) const

pure virtual

Convert a string into an identity.

If the string does not parse correctly, the operation throws IdentityParseException.

Parameters

str	The string to convert into an identity.

Returns: The identity.

See also: identityToString

Deprecated:: stringToIdentity() is deprecated, use the static stringToIdentity() method instead.

◆ stringToProxy()

virtual ObjectPrx Ice::Communicator::stringToProxy ( const ::std::string & str ) const

pure virtual

Convert a stringified proxy into a proxy.

For example, MyCategory/MyObject:tcp -h some_host -p 10000 creates a proxy that refers to the Ice object having an identity with a name "MyObject" and a category "MyCategory", with the server running on host "some_host", port 10000. If the stringified proxy does not parse correctly, the operation throws one of ProxyParseException, EndpointParseException, or IdentityParseException. Refer to the Ice manual for a detailed description of the syntax supported by stringified proxies.

Parameters

str	The stringified proxy to convert into a proxy.

Returns: The proxy, or nil if str is an empty string.

See also: proxyToString

◆ waitForShutdown()

virtual void Ice::Communicator::waitForShutdown	(	)
throw	(
	)

pure virtual

Wait until the application has called shutdown (or destroy).

On the server side, this operation blocks the calling thread until all currently-executing operations have completed. On the client side, the operation simply blocks until another thread has called shutdown or destroy.

A typical use of this operation is to call it from the main thread, which then waits until some other thread calls shutdown. After shut-down is complete, the main thread returns and can do some cleanup work before it finally calls destroy to shut down the client functionality, and then exits the application.
