java.lang.Objectorg.eclipse.core.internal.resources.InternalTeamHook
org.eclipse.core.resources.team.TeamHook
A general hook class for operations that team providers may be interested in participating in. Implementors of the hook should provide a concrete subclass, and override any methods they are interested in.
This class is intended to be subclassed by the team component in
conjunction with the org.eclipse.core.resources.teamHook
standard extension point. Individual team providers may also subclass this
class. It is not intended to be subclassed by other clients. The methods
defined on this class are called from within the implementations of
workspace API methods and must not be invoked directly by clients.

public IResourceRuleFactory getRuleFactory(IProject project)
setRuleFactory
.
This method must not return null
. If no special rules are required
by the team hook for the given project, the value of the defaultFactory
field should be returned.
This default implementation always returns the value of the defaultFactory
field. Subclasses may override and provide a subclass of ResourceRuleFactory
.
project

getRuleFactory
for the given project
The supplied factory must not be null
. If no special rules are required
by the team hook for the given project, the value of the defaultFactory
field should be used.
Note that the new rule factory will only take effect for resource changing operations that begin after this method completes. Care should be taken to avoid calling this method during the invocation of any resource changing operation (in any thread). The best time to change rule factories is during resource change notification when the workspace is locked for modification.

The implementation of this method runs "below" the resources API and is therefore very restricted in what resource API method it can call. The list of useable methods includes most resource operations that read but do not update the resource tree; resource operations that modify resources and trigger deltas must not be called from within the dynamic scope of the invocation of this method.
This method should be overridden by subclasses that want to control what links are created. The default implementation of this method allows all links to be created.
