Class SpaceAccessor

java.lang.Object
  |
  +--SpaceAccessor

public final class SpaceAccessor

extends java.lang.Object

This class can be used as replacement for the SpaceAccessor class used in the book: JavaSpaces(tm) Principles, Patterns and Practice" by Freeman, Hupfer, Arnold I took the liberty to refactor Luba Powell's SpaceWrapper class and this is the result. It shouldn't break (I hope) any(?) existing code which uses the original SpaceAccessor. Thanks Luba for your code! (robert.hellwig@sun.com)

Since:

21.07.2001
Updated: mnoble.@cfa.harvard.edu, version 1.1, 24.08.2002
- Added code to check com.sun.jini.outrigger.spaceName property before defaulting to using SPACE_DEFAULT_NAME.
- Replaced use of SpaceAccessorException with standard Exception, for simplicity.
- Commented out intrusive "Searching for space" message
- Added code to check com.sun.jini.lookup.locator property before defaulting to using DEFAULT_JINI_URL
- Need to format this better for JavaDoc!
