Examples

Changes for version 1.00

  • !!! This is a major upgrade that changes API. It's strongly advised to study revised documentation and update your code where necessary !!!
  • !!! Data structures created on the server by previous versions of the module are incompatible with this release. Existing collections must be recreated after updating to this release. !!!
  • CHANGES:

  • In the parameters of the methods 'redis' may be either a Redis object or a hash reference of parameters to create a Redis object.
