Methods
- get_service(self, protocol, query = '', minimize = '', maximize = '')
Return at most one service that matches the specified query.
The protocol can be an actual class or interface, or the name of a class or interface in the form '<module_name>.<class_name>'.
Return None if no such service is found.
If no query is specified then a service that provides the specified protocol is returned (if one exists).
NOTE: If more than one service exists that match the criteria then Don't try to guess which one it will return - it is random!
- get_service_properties(self, service_id)
Return the dictionary of properties associated with a service.
If no such service exists a 'ValueError' exception is raised.
The properties returned are 'live' i.e. changing them immediately changes the service registration.
- get_services(self, protocol, query = '', minimize = '', maximize = '')
Return all services that match the specified query.
The protocol can be an actual class or interface, or the name of a class or interface in the form '<module_name>.<class_name>'.
If no services match the query, then an empty list is returned.
If no query is specified then all services that provide the specified protocol are returned (if any exist).
- register_service(self, protocol, obj, properties = None)
Register a service.
The protocol can be an actual class or interface, or the name of a class or interface in the form:
'foo.bar.baz'
Which is turned into the equivalent of an import statement that looks like:
from foo.bar import baz
Return a service Id that can be used to unregister the service and to get/set any service properties.
If 'obj' does not implement the specified protocol then it is treated as a 'service factory' that will be called the first time a service of the appropriate type is requested. A 'service factory' is simply a callable that takes the properties specified here as keyword arguments and returns an object. For really lazy loading, the factory can also be specified as a string which is used to import the callable.
- set_service_properties(self, service_id, properties)
Set the dictionary of properties associated with a service.
If no such service exists a 'ValueError' exception is raised.
- unregister_service(self, service_id)
Unregister a service.
If no such service exists a 'ValueError' exception is raised.
