Method Details
-
close
void close()Destroy the communicator. This Java-only method overrides close in java.lang.AutoCloseable and does not throw any exception.- Specified by:
close
in interfaceAutoCloseable
- See Also:
-
destroy
void destroy()Destroy the communicator. This operation callsshutdown()
implicitly. Callingdestroy()
cleans up memory, and shuts down this communicator's client functionality and destroys all object adapters. Subsequent calls todestroy()
are ignored.- See Also:
-
shutdown
void shutdown()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 usewaitForShutdown()
to wait for the completion of all requests. -
waitForShutdown
void waitForShutdown()Wait until the application has calledshutdown()
(ordestroy()
). 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 calledshutdown()
ordestroy()
. A typical use of this operation is to call it from the main thread, which then waits until some other thread callsshutdown()
. After shut-down is complete, the main thread returns and can do some cleanup work before it finally callsdestroy()
to shut down the client functionality, and then exits the application. -
isShutdown
boolean isShutdown()Check whether communicator has been shut down.- Returns:
- True if the communicator has been shut down; false otherwise.

stringToProxy
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
Convert a proxy into a string.- Parameters:
obj
- The proxy to convert into a stringified proxy.- Returns:
- The stringified proxy, or an empty string if
obj
is nil. - See Also:
-
propertyToProxy
Convert a set of proxy properties into a proxy. The "base" name supplied in theproperty
argument refers to a property containing a stringified proxy, such asMyProxy=id:tcp -h localhost -p 10000
. Additional properties configure local settings for the proxy, such asMyProxy.PreferSecure=1
. The "Properties" appendix in the Ice manual describes each of the supported proxy properties.- Parameters:
property
- The base property name.- Returns:
- The proxy.
-
proxyToProperty
Convert a proxy to a set of proxy properties.- Parameters:
proxy
- The proxy.property
- The base property name.- Returns:
- The property set.
-
stringToIdentity
Deprecated.stringToIdentity() is deprecated, use the static stringToIdentity() method instead.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
Convert an identity into a string.- Parameters:
ident
- The identity to convert into a string.- Returns:
- The "stringified" identity.
- See Also:
-
createObjectAdapter
Create a new object adapter. The endpoints for the object adapter are taken from the propertyname.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
Create a new object adapter with endpoints. This operation sets the propertyname.Endpoints
, and then callscreateObjectAdapter(java.lang.String)
. 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.
- See Also:
-
createObjectAdapterWithRouter
Create a new object adapter with a router. This operation creates a routed object adapter. Calling this operation with an empty name will result in a UUID being generated for the name.- Parameters:
name
- The object adapter name.rtr
- The router.- Returns:
- The new object adapter.
- See Also:
-
addObjectFactory
Deprecated.addObjectFactory() is deprecated, use ValueFactoryManager::add() instead.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.- See Also:
-
findObjectFactory
Deprecated.findObjectFactory() is deprecated, use ValueFactoryManager::find() instead.Find an object factory registered with this communicator.- Parameters:
id
- The type id for which the factory can create instances, or an empty string for the default factory.- Returns:
- The object factory, or null if no object factory was found for the given id.

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 operationice_locator
on the proxy, or for an object adapter by callingObjectAdapter.setLocator(com.zeroc.Ice.LocatorPrx)
on the object adapter.- Parameters:
loc
- The default locator to use for this communicator.- See Also:
