public final class DefaultScope extends org.eclipse.core.internal.preferences.AbstractScope implements IScopeContext
Default preferences are not persisted to disk.
The path for preferences defined in the default scope hierarchy
is as follows: /default/<qualifier>
Note about product preference customization:
Clients who define their own IProduct
are able to specify a product key of "preferenceCustomization".
(defined as a constant in IProductConstants)
Its value is either a URL or a file-system path to a
file whose contents are used to customize default preferences.
This class is not intended to be subclassed. This class may be instantiated.

IScopeContextnull 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.

is unavailable, or is not applicable to this scope.
