Class ProjectScope
java.lang.Object
org.eclipse.core.resources.ProjectScope
-
All Implemented Interfaces:
-
IScopeContext
-
public final class ProjectScope
- extends
Object
- implements
IScopeContext
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.

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
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.
