public final class BundlePermission
A bundle's authority to require or provide a bundle or to receive or attach fragments.
A bundle symbolic name defines a unique fully qualified name.
For example:
org.osgi.example.bundle
BundlePermission
has four actions: PROVIDE
,
REQUIRE
,HOST
, and FRAGMENT
.
The PROVIDE
action implies the REQUIRE
action.

public BundlePermission(String symbolicName, String actions)
Bundle Permissions are granted over all possible versions of a bundle.
A bundle that needs to provide a bundle must have the appropriate
BundlePermission
for the symbolic name; a bundle that
requires a bundle must have the appropriate BundlePermssion
for that symbolic name; a bundle that specifies a fragment host must have
the appropriate BundlePermission
for that symbolic name.

public boolean implies(Permission p)
This method checks that the symbolic name of the target is implied by the
symbolic name of this object. The list of BundlePermission
actions must either match or allow for the list of the target object to
imply the target BundlePermission
action.
The permission to provide a bundle implies the permission to require the named symbolic name.
