Interface IRemoteJSpaceAdmin

All Superinterfaces:

Remote

public interface IRemoteJSpaceAdmin
extends Remote

This interface contains all the administrative methods that GigaSpaces provides to control the JavaSpaces service.

 Usage:
        IJSpace space = (IJSpace) SpaceFinder.find(spaceUrl);
        IRemoteJSpaceAdmin spaceAdmin = (IRemoteJSpaceAdmin)space.getAdmin();

 The code examples on each method assumes the above usage.
