Examples of org.osgi.framework.Bundle.adapt()

org.osgi.framework.Bundle.adapt()
Adapt this bundle to the specified type.
Adapting this bundle to the specified type may require certain checks, including security checks, to succeed. If a check does not succeed, then this bundle cannot be adapted and {@code null} is returned. @param < A> The type to which this bundle is to be adapted. @param type Class object for the type to which this bundle is to beadapted. @return The object, of the specified type, to which this bundle has beenadapted or {@code null} if this bundle cannot be adapted to thespecified type. @throws SecurityException If the caller does not have the appropriate{@code AdaptPermission[type,this,ADAPT]}, and the Java Runtime Environment supports permissions. @since 1.6
