    • executeWithRetry

      public <T> T executeWithRetry(int nRetries, Function<OrientGraph,T> function)
      Tries to execute a lambda in a transaction, retrying it if an ONeedRetryException is thrown.

      If the Graph has an active transaction, then the transaction has to be empty (no operations executed yet) and after the execution you will be in a new transaction.

      Type Parameters:
      T - the return type of the lambda
      Parameters:
      nRetries - the maximum number of retries (> 0)
      function - a lambda containing application code to execute in a commit/retry loop
      Returns:
      The result of the execution of the lambda
      Throws:
      IllegalStateException - if there are operations in the current transaction
      ONeedRetryException - if the maximum number of retries is executed and all failed with an ONeedRetryException
      IllegalArgumentException - if nRetries is <= 0
      UnsupportedOperationException - if this type of graph does not support automatic commit/retry or does not support transactions
