  • Method Details

    • getProviderContext

      ProviderContext getProviderContext()

    • getId

      NodeId getId()

    • getPath

      TagPath getPath()
      Returns the full path of the node.

    • getPropertyModel

      BoundPropertySet getPropertyModel()
      Returns the property model of the node.

    • getExpressionBindablePropertyModel

      Optional<PropertyValueSource> getExpressionBindablePropertyModel()

    • isLeased

      boolean isLeased()
      Indicates whether the node is "leased", which means it has a heavy-weight subscription on it. In other words, the system knows that an entity is interested in receiving the fastest value changes possible.

    • getExpressionParseContext

      ExpressionParseContext getExpressionParseContext()

    • dispatchScriptEvent

      void dispatchScriptEvent(String id, Object... params)
      Fires a script event of the given id, with the specified parameters. This is the mechanism by which actors can contribute to the tag event script system.

    • persistProperty

      <T> void persistProperty(Property<T> prop, T value)
      This requests that the given property value be saved persistently. It also has the side effect of inserting the property in the node configuration and synchronizing it across redundancy. Cannot be used for properties that are dynamic/bound.

    • isPropertyDynamic

      boolean isPropertyDynamic(Property<?> prop)
      Indicates that the given property is bound or otherwise dynamic. This would mean that the property cannot be modified through writing or saved through the persistProperty call. Instead, it would need to be edited through other tag modification means.

    • save

      void save()
      Requests that the system save the full local config of the node.
