  • Constructor Details

    • SearchLimit

      protected SearchLimit(long cPtr, boolean cMemoryOwn)

  • Method Details

      protected static long getCPtr(SearchLimit obj)

    • finalize

      protected void finalize()
      Overrides:
      finalize in class SearchMonitor

    • delete

      public void delete()
      Overrides:

    • keepAliveDecisionBuilder

      public void keepAliveDecisionBuilder(DecisionBuilder db)
      Overrides:
      keepAliveDecisionBuilder in class SearchMonitor

    • crossed

      public boolean crossed()
      Returns true if the limit has been crossed.

    • check

      public boolean check()
      This method is called to check the status of the limit. A return
      value of true indicates that we have indeed crossed the limit. In
      that case, this method will not be called again and the remaining
      search will be discarded.

    • init

      public void init()
      This method is called when the search limit is initialized.

    • copy

      public void copy(SearchLimit limit)
      Copy a limit. Warning: leads to a direct (no check) downcasting of 'limit'
      so one needs to be sure both SearchLimits are of the same type.

    • makeClone

      public SearchLimit makeClone()
      Allocates a clone of the limit.

      public void enterSearch()
