Last change on this file since 8c31865 was 8c31865, checked in by Frederik Heber <heber@…>, 13 years ago

Added new class LinkedCellArrayCache that performs the lazy updates on a LinkedCellArray.

  • basically, we cache all write operations and perform them first when there is a read operation that requires an up-to-date structure.
  • we cannot do this via the Cacheable pattern was there we always have a return value of the update structure. It is currently unknown how to initialize a cached pointer (apart from always checking for this in the update function).
  • Property mode set to 100644
