org.eclipse.core.resources
Class ProjectScope

java.lang.Object
  extended byorg.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.

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 Detail

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 subnode 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
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: 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 unapplicable to this scope.

Specified by:
getLocation in interface IScopeContext
Returns:
a writable location in the filesystem or null

getName

public String getName()
Description copied from interface: IScopeContext
Return the name of the scope that this context is associated with. Must not be null.

Specified by:
getName in interface IScopeContext
Returns:
the name of the scope

equals

public boolean equals(Object obj)

hashCode

public int hashCode()
