public final class BundleDefaultsScope
extends org.eclipse.core.internal.preferences.AbstractScope
The bundle defaults are the defaults are default values which have been set either by the bundle's preference initializer or by a customization file supplied with the bundle.
Bundle default preferences are not persisted to disk.
The path for preferences defined in the bundle defaults scope hierarchy
is as follows: /bundle_defaults/<qualifier>
This class is not intended to be subclassed. This class may be instantiated.

if the node cannot be determined.
The given qualifier must not be null
but may be a path
to a sub-node within the scope.
An example of a qualifier in Eclipse 2.1 would be the plug-in identifier that the preference is associated with (e.g. the "org.eclipse.core.resources" plug-in defines the "description.autobuild" preference).
This method can be used to determine the appropriate preferences node
to aid in setting key/value pairs. For instance:
new InstanceScope().getNode("org.eclipse.core.resources");
returns the preference node in the instance scope where the preferences
for "org.eclipse.core.resources" are stored.
