Method Detail

getSymbolicName

public String getSymbolicName()

Description copied from interface: BundleRevision

Returns the symbolic name for this bundle revision.

Specified by:

getSymbolicName in interface BundleRevision

Returns:

The symbolic name for this bundle revision.

getVersion

public org.osgi.framework.Version getVersion()

Description copied from interface: BundleRevision

Returns the version for this bundle revision.

Specified by:

getVersion in interface BundleRevision

Returns:

The version for this bundle revision, or Version.emptyVersion if this bundle revision has no version information.

getDeclaredCapabilities

public List<BundleCapability> getDeclaredCapabilities(String namespace)

Description copied from interface: BundleRevision

Returns the capabilities declared by this bundle revision.

Specified by:

getDeclaredCapabilities in interface BundleRevision

Parameters:

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

Returns:

An unmodifiable list containing the declared BundleCapabilitys from the specified namespace. The returned list will be empty if this bundle revision declares no capabilities in the specified namespace. The list contains the declared capabilities in the order they are specified in the manifest.

getDeclaredRequirements

public List<BundleRequirement> getDeclaredRequirements(String namespace)

Description copied from interface: BundleRevision

Returns the requirements declared by this bundle revision.

Specified by:

getDeclaredRequirements in interface BundleRevision

Parameters:

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

Returns:

An unmodifiable list containing the declared BundleRequirements from the specified namespace. The returned list will be empty if this bundle revision declares no requirements in the specified namespace. The list contains the declared requirements in the order they are specified in the manifest.

getTypes

public int getTypes()

Description copied from interface: BundleRevision

Returns the special types of this bundle revision. The bundle revision type values are:

If this bundle revision is not one or more of the defined types then 0 is returned.

Specified by:

getTypes in interface BundleRevision

Returns:

The special types of this bundle revision. The type values are ORed together.

getWiring

public BundleWiring getWiring()

Description copied from interface: BundleRevision

Returns the bundle wiring which is using this bundle revision.

Specified by:
