public final class ConfigurationScope extends org.eclipse.core.internal.preferences.AbstractScope implements IScopeContext
Configuration preferences are stored on a per configuration basis in the platform's configuration area. (The configuration area typically contains the list of plug-ins available for use, various settings (those shared across different instances of the same configuration) and any other such data needed by plug-ins.)
The path for preferences defined in the configuration scope hierarchy
is as follows: /configuration/<qualifier>
This class is not intended to be subclassed. This class may be instantiated.

to write files that will have the same sharing/scope properties as
preferences defined in this scope.

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.
