    • addScenario

      public SafetyValve addScenario(SafetyValve.RelievingScenario scenario)
      Adds a relieving scenario definition to the valve.
      Parameters:
      scenario - the scenario to add
      Returns:
      the current valve instance for chaining

    • setRelievingScenarios

      public void setRelievingScenarios(List<SafetyValve.RelievingScenario> scenarios)
      Replace the relieving scenarios with the provided collection.
      Parameters:
      scenarios - scenarios to store on the valve

    • clearRelievingScenarios

      public void clearRelievingScenarios()
      Removes all relieving scenarios from the valve.

    • getRelievingScenarios

      public List<SafetyValve.RelievingScenario> getRelievingScenarios()
      Returns:
      immutable view of configured scenarios

    • setActiveScenario

      public void setActiveScenario(String name)
      Sets the active relieving scenario by name. If the scenario does not exist the active definition is not changed.
      Parameters:
      name - scenario identifier

    • getActiveScenarioName

      public Optional<String> getActiveScenarioName()
      Returns:
      the name of the active scenario, if any

    • getActiveScenario

      public Optional<SafetyValve.RelievingScenario> getActiveScenario()
      Returns the active relieving scenario or Optional.empty() if no scenario is active.
      Returns:
      optional containing the active scenario

    • ensureDefaultScenario

      public void ensureDefaultScenario()
      Ensures that at least one scenario exists by creating a default vapor relieving scenario when no user supplied definitions are present.

    • getPressureSpec

      public double getPressureSpec()

      Getter for the field pressureSpec.

      Returns:
      the pressureSpec

    • setPressureSpec

      public void setPressureSpec(double pressureSpec)

      Setter for the field pressureSpec.

      Parameters:
      pressureSpec - the pressureSpec to set

    • getFullOpenPressure

      public double getFullOpenPressure()

      Getter for the field fullOpenPressure.

      Returns:
      the fullOpenPressure

    • setFullOpenPressure
