Creates a new capsule scope on top of the active one and executes the given function in it.
Creates a new capsule scope on top of the active one and executes the given function in it. So the function sees the new capsule scope as the current one.

Adds the given start logic.
Adds the given start logic. The logic is executed immediately.

Adds the given stop logic.
Adds the given stop logic. The given function will be executed when the current scope is stopped.

Returns the first available service of the specified class which satisfies the filter if available.
Returns the first available service of the specified class which satisfies the filter if available. If the service
is not available, it returns None. The service is not explicitly released.

service if available
Returns the highest-ranked service of the specified type if available.
Returns the highest-ranked service of the specified type if available. The service is not explicitly released. It's assumed that the service will be used until the bundle stops. Doesn't take type parameters into account!

Like service with filter but returns the service reference.

Like service but returns the reference so you can access meta information about that service.
Like service but returns the reference so you can access meta information about that service.
An implicit conversion adds a service property to the reference, so you can simply use that to obtain the service.

Converts a service reference to a rich service reference so one can easily obtain the
corresponding service by calling service, for example.

Activates the given inner logic as long as the first service of the given type is present.
Activates the given inner logic as long as the first service of the given type is present. This implements the concept of required services. The inner logic is started as soon as a service s of the given type gets present and stopped when s is removed.
Idea for roadmap: Fallback to another service if s is removed and another service of the type is available (reevaluate capsule).
Defines a handler f to be executed when the bundle becomes active.
Defines a handler f to be executed when the bundle becomes active. f is executed as soon as the bundle
activator's start method is called. This should be called in the constructor of your activator.
In f, you have the opportunity to add so called capsules, which have their own start and stop methods
(a kind of mini bundles). Their stop methods will be invoked as soon as the bundle activator's stop method
is called. So you have the big chance here to encapsulate start and stop logic at one place, making the bundle
activator less error-prone, better readable and easier to write.

Like the same-named method which expects the service PID but takes the service PID from the given object class definition and registers a corresponding meta type provider so a nice configuration GUI will be created.

Executes the given handler whenever a new factory configuration is created. Whenever a factory configuration is changed, the correct capsules registered in the corresponding handler are stopped and the handler is executed again with the new factory configuration. When the factory configuration is removed, the corresponding capsules are stopped.

When the service disappears, the capsules added in the handlers are stopped.
You can wait on a bunch of services if you nest whenServicePresent methods.

Executes the given handler with the first available service of the specified class which satisfies the filter if available.
Executes the given handler with the first available service of the specified class which satisfies the filter
if available. If it's not available, it still executes it but with None.
When the handler returns, the service is released using org.osgi.framework.BundleContext#ungetService.
