    • setDependencyErrorHandler

      public void setDependencyErrorHandler(DependencyErrorHandler dependencyErrorHandler)
      Sets an error handler to be called if the associated node could not be executed due to a dependency error. The handler is called in the same context as the computation of the task node would have been.

      Setting this property will override any previously set value for this property.

      Parameters:
      dependencyErrorHandler - the error handler to be called if the associated node could not be executed due to a dependency error. This argument can be null if there is nothing to do in case of a dependency error.

      Sets the executor used to execute the actions of the task nodes. Setting the executor will override any previously set value.
      Parameters:
      executor - the executor used to execute the actions of the task nodes. This argument cannot be null.

    • build

      public TaskNodeProperties build()
      Creates a snapshot of the current state of this Builder. Further adjustment of this Builder will not affect the returned TaskNodeProperties.
      Returns:
      a snapshot of the current state of this Builder. This method may never return null.
