Method Detail

getClassLoader

public java.lang.ClassLoader getClassLoader()

Description copied from interface: BundleWiring

Returns the class loader for this bundle wiring. Since a bundle refresh creates a new bundle wiring for a bundle, different bundle wirings for the same bundle will have different class loaders.

Specified by:

getClassLoader in interface BundleWiring

Overrides:

getClassLoader in class BundleWiringImpl

Returns:

The class loader for this bundle wiring. If this bundle wiring is not in use or this bundle wiring is for a fragment revision, null will be returned.

getCapabilities

public java.util.List<BundleCapability> getCapabilities(java.lang.String namespace)

Description copied from interface: BundleWiring

Returns the capabilities provided by this bundle wiring.

Only capabilities considered by the resolver are returned. For example, capabilities with effective directive not equal to resolve are not returned.

A capability may not be required by any bundle wiring and thus there may be no wires for the capability.

A bundle wiring for a non-fragment revision provides a subset of the declared capabilities from the bundle revision and all attached fragment revisions^†. Not all declared capabilities may be provided since some may be discarded. For example, if a package is declared to be both exported and imported, only one is selected and the other is discarded.

A bundle wiring for a fragment revision with a symbolic name must provide exactly one identity capability.

† The identity capability provided by attached fragment revisions must not be included in the capabilities of the host bundle wiring.

Specified by:

getCapabilities in interface BundleWiring

Overrides:

getCapabilities in class BundleWiringImpl

Parameters:

namespace - The namespace of the capabilities to return or null to return the capabilities from all namespaces.

Returns:

A list containing a snapshot of the BundleCapabilitys, or an empty list if this bundle wiring provides no capabilities in the specified namespace. If this bundle wiring is not in use, null will be returned. For a given namespace, the list contains the capabilities in the order the capabilities were specified in the manifests of the bundle revision and the attached fragments^† of this bundle wiring. There is no ordering defined between capabilities in different namespaces.

getNativeLibraries

public java.util.List<NativeLibrary> getNativeLibraries()

Overrides:

getNativeLibraries in class BundleWiringImpl

getClassByDelegation

public java.lang.Class getClassByDelegation(java.lang.String name)
                                     throws java.lang.ClassNotFoundException

Overrides:

getClassByDelegation in class BundleWiringImpl

Throws:

java.lang.ClassNotFoundException

getResourceByDelegation

public java.net.URL getResourceByDelegation(java.lang.String name)

Overrides:

getResourceByDelegation in class BundleWiringImpl

getResourcesByDelegation

public java.util.Enumeration getResourcesByDelegation(java.lang.String name)

Overrides:

getResourcesByDelegation in class BundleWiringImpl

dispose

public void dispose()

Overrides:

dispose in class BundleWiringImpl
