java.lang.Object
   org.eclipse.ui.internal.handlers.SlaveHandlerService

All known Subclasses:   org.eclipse.ui.internal.handlers.NestableHandlerService,
SlaveHandlerService
public class SlaveHandlerService implements IHandlerService(Code)
A handler service which delegates almost all responsibility to the parent service. It is only responsible for disposing of locally activated handlers when it is disposed.

This class is not intended for use outside of the org.eclipse.ui.workbench plug-in.


since:
   3.2


Field Summary
final protected  ExpressiondefaultExpression
     The default expression to use when SlaveHandlerService.activateHandler(String,IHandler) is called.
final protected  MaplocalActivationsToParentActivations
     A map of the local activation to the parent activations.
final protected  IHandlerServiceparent
     The parent handler service to which all requests are ultimately routed.
final protected  SetparentActivations
     The activations registered with the parent handler service.

Constructor Summary
public  SlaveHandlerService(IHandlerService parentHandlerService, Expression defaultExpression)
     Constructs a new instance.
Parameters:
  parentHandlerService - The parent handler service for this slave; must not benull.
Parameters:
  defaultExpression - The default expression to use if none is provided.

Field Detail
defaultExpression
final protected Expression defaultExpression(Code)
The default expression to use when SlaveHandlerService.activateHandler(String,IHandler) is called. Handlers contributed using that method will only be active when this service is active. However, this expression will be used for conflict resolution.



localActivationsToParentActivations
final protected Map localActivationsToParentActivations(Code)
A map of the local activation to the parent activations. If this service is inactive, then all parent activations are null. Otherwise, they point to the corresponding activation in the parent service.



parent
final protected IHandlerService parent(Code)
The parent handler service to which all requests are ultimately routed. This value is never null.



parentActivations
final protected Set parentActivations(Code)
The activations registered with the parent handler service. This value is never null.




Constructor Detail
SlaveHandlerService
public SlaveHandlerService(IHandlerService parentHandlerService, Expression defaultExpression)(Code)
Constructs a new instance.
Parameters:
  parentHandlerService - The parent handler service for this slave; must not benull.
Parameters:
  defaultExpression - The default expression to use if none is provided. This isprimarily used for conflict resolution. This value may benull.
