Package org.eclipse.core.resources

Class ProjectScope

java.lang.Object
org.eclipse.core.internal.preferences.AbstractScope
org.eclipse.core.resources.ProjectScope
All Implemented Interfaces:
IScopeContext
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.

Since:
3.0

    • ProjectScope

      public ProjectScope(IProject context)
      Create and return a new project scope for the given project. The given project must not be null.
      Parameters:
      context - the project
      Throws:
      IllegalArgumentException - if the project is null

  • Method Details

    • 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
      Overrides:
      getNode in class org.eclipse.core.internal.preferences.AbstractScope
      Parameters:
      qualifier - a qualifier for the preference name
      Returns:
      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.
