Interface ServiceDependencySorter
- All Known Implementing Classes:
- ComparatorServiceDependencySorter
public interface ServiceDependencySorter
SPI for sorting OSGi bundles based on their service dependency. Given a
number of bundles, implementors of this interface will return a list
referencing the bundles in the order in which they should be shutdown based
on their OSGi service dependencies.
It is considered that bundle A depends on bundle B if A uses a service that
belongs to a bundle which depends on B or is B itself. Note that bundles can
depend on each other : A -> B -> A.
Thus implementations should 'sort' direct, circular graphs without any
guarantee on the node used for start.
