# Assume that we have a service registry with a service registered with the name 'foo' # We can fetch the properties of this service as follows: from org.osgi.framework import BundleContext from org.osgi.framework import ServiceReference # Get a reference to the service registry context = BundleContext() # Find the service reference with the name 'foo' foo_ref = context.getServiceReference('foo') # Fetch the properties of the service foo_properties = foo_ref.getProperties() # Print the properties to the console for key, value in foo_properties.items(): print(f'{key}: {value}')
# Assume that we have a service registry with a service registered with the name 'bar' # We can use the service object to interact with the service as follows: from org.osgi.framework import BundleContext from org.osgi.framework import ServiceReference # Get a reference to the service registry context = BundleContext() # Find the service reference with the name 'bar' bar_ref = context.getServiceReference('bar') # Get the service object from the reference bar_service = context.getService(bar_ref) # Call a method on the service object result = bar_service.do_something() # Print the result to the console print(f'Result: {result}')In this example, we are using the service object to interact with a service named 'bar' that is registered in a service registry. We first get a reference to the service registry and then fetch the service reference with the name 'bar'. We then use this reference to fetch the service object and call a method on it. We finally print the result to the console. Package Library: The ServiceReference class is part of the org.osgi.framework package library.
