    • initialize

      public void initialize()
      Initialization for extension which will initialise access to the extension repository where selectors will be configured. Note that we need to do the messing around with intialization synchronization due to two issues: 1. The initialization method can be called multiple times during a node startup. 2. The retrieval of the Extensions cache template would recursively trigger this logic, so we need to avoid synchronizing in a recursive call to avoid deadlock. The approach below satisfies both these problems, although should be considered a workaround for now.
      Specified by:
      initialize in interface oracle.communication.brm.charging.dsl.CustomDslExtension

    • execute

      public oracle.communication.brm.charging.dsl.runtime.Result execute(oracle.communication.brm.charging.dsl.runtime.Input input, String id, String type)
      Specified by:
      execute in interface oracle.communication.brm.charging.dsl.CustomDslExtension
      Parameters:
      input - the rating context
      id - the internal id (internal pricing ID for charge selector or alteration selector)
      type - type is CHARGE if called from a Charge RPS and ALTERATION if called from a Alteration RPS
      Returns:
      result - the value of the evaluation (the internal Id of the rate-plan) or null if no match.
