Known Subclasses:: DependentMultiService

I am a collection of multiple services.

I am useful if you have a large number of services and need to categorize them, or you need to write a protocol that can access multiple services through one factory, such as a protocol that maps services to virtual hosts, like POP3.

Method Summary
	`__init__(self, serviceName, serviceParent)`
	`_cbAttachServiceNames(self, result, services)` I massage the result of a DeferredList into something that's a bit easier to work with (see `stopService`'s __doc__).
	`addService(self, service)` Add a Service to me.
	`removeService(self, service)` Remove a Service from me.
	`startService(self)` Start all of my Services.
	`stopService(self)` Stop all of my Services.
Inherited from _AbstractServiceCollection
	`getServiceNamed(self, serviceName)` Retrieve the named service from this application.
Inherited from ApplicationService
	`disownServiceParent(self)` Have my parent disown me.
	`get_application(self)`
	`set_application(self, application)`
	`setApplication(self, application)`
	`setServiceParent(self, serviceParent)` Set my parent, which must be a service collection of some kind.
	`upgradeToVersion1(self)`
Inherited from Accessor
	`__delattr__(self, k)`
	`__getattr__(self, k)`
	`__setattr__(self, k, v)`
	`reallyDel(self, k)` actually del self.k without incurring side-effects.
	`reallySet(self, k, v)` actually set self.k to v without incurring side-effects.
Inherited from Versioned
	`__getstate__(self, dict)` Get state, adding a version number to it on its way out.
	`__setstate__(self, state)`
	`versionUpgrade(self)` (internal) Do a version upgrade.

Method Details

_cbAttachServiceNames(self, result, services)

I massage the result of a DeferredList into something that's a bit easier to work with (see stopService's __doc__).

addService(self, service)

Add a Service to me.

Overrides:: twisted.internet.app._AbstractServiceCollection.addService

removeService(self, service)

Remove a Service from me.

Overrides:: twisted.internet.app._AbstractServiceCollection.removeService

startService(self)

Start all of my Services.

Overrides:: twisted.internet.app.ApplicationService.startService

stopService(self)

Stop all of my Services.

I return a Deferred that results in a dict that looks like {serviceObject: (successOrFailure, result)}, where successOrFailure is a boolean and result is the result of the Deferred returned by serviceObject.stopService.

Overrides:: twisted.internet.app.ApplicationService.stopService
