- 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.AbstractScopeObject representing the project scope in the Eclipse preferences hierarchy. Can be used as a context for searching for preference values (in theorg.eclipse.core.runtime.IPreferencesServiceAPIs) 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.

- 3.0

getNode
public IEclipsePreferences getNode(String qualifier)
Description copied from interface:IScopeContextReturn the preferences node that contains the preferences for the given qualifier ornullif the node cannot be determined. The given qualifier must not benullbut 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:
getNodein interfaceIScopeContext- Overrides:
getNodein classorg.eclipse.core.internal.preferences.AbstractScope- Parameters:
qualifier- a qualifier for the preference name- Returns:
- the node containing the plug-in preferences or
null - See Also:
IPreferencesService

getLocation
public IPath getLocation()
Description copied from interface:IScopeContextReturn 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
nullif the location is not known, is unavailable, or is not applicable to this scope.- Specified by:
getLocationin interfaceIScopeContext- Specified by:
getLocationin classorg.eclipse.core.internal.preferences.AbstractScope- Returns:
- a writable location in the file system or
null
-
getName
public String getName()
Description copied from interface:IScopeContextReturn the name of the scope that this context is associated with. Must not benull.- Specified by:
getNamein interfaceIScopeContext- Specified by:

- the name of the scope
