Class ProjectScope

  • All Implemented Interfaces:

    public final class ProjectScope
    extends org.eclipse.core.internal.preferences.AbstractScope
    Object representing the project scope in the Eclipse preferences hierarchy. Can be used as a context for searching for preference values (in the org.eclipse.core.runtime.IPreferencesService APIs) or for determining the correct preference node to set values in the store.

    Project preferences are stored on a per project basis in the project's content area as specified by IProject#getLocation.

    The path for preferences defined in the project scope hierarchy is as follows: /project/<projectName>/<qualifier>

    This class is not intended to be subclassed. This class may be instantiated.

        public ProjectScope​(IProject context)

      • getNode

        public IEclipsePreferences getNode​(String qualifier)
        Description copied from interface: IScopeContext
        Return the preferences node that contains the preferences for the given qualifier or null 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.

        Specified by:
        getNode in interface IScopeContext
        getNode in class org.eclipse.core.internal.preferences.AbstractScope
        qualifier - a qualifier for the preference name
        the node containing the plug-in preferences or null

        Description copied from interface: IScopeContext
        Return a path to a location in the file-system where clients are able to write files that will have the same sharing/scope properties as preferences defined in this scope.

        Implementors may return null if the location is not known, is unavailable, or is not applicable to this scope.
