Interface InputPortInstance

All Superinterfaces:
PortInstance
public interface InputPortInstance extends PortInstance
A runtime instance of a LogicalPort.

  • Method Details

    • getSourcePath

      GraphPath getSourcePath()
      Returns the path to the source port. This may be null in the case of a disconnected optional port.
      Returns:
      the source path

    • getStatistics

      List<LogicalStatistic> getStatistics()
      Returns statistics for this port. The returned statistics are broken down by LogicalStatistic.nodeID(), LogicalStatistic.definition(), and LogicalStatistic.path(). If this port corresponds to an composite port then there is an entry for each component of this composite port.
      Returns:
      the statistics for this port.

    • getHistoricalStatistics

      StatisticsMap getHistoricalStatistics()
      Returns aggregations for subgraphs that have been flushed from the history.
      Returns:
      aggregations for subgraphs that have been flushed from the history.

    • getSubgraphs

      List<? extends LogicalGraphInstanceView> getSubgraphs()
      Returns a list of subgraphs that were executed for this connection. Most connections require no sub-graphs; this is used by connections that need to dynamically distribute data. The setting EngineConfig.subgraphHistorySize(int) may be used to limit the number of subgraphs that are retained. If this port corresponds to an composite port then this will return an empty list.
      Returns:
      a list of subgraphs that were executed for this connection

    • getSnapshot

      InputPortInstance getSnapshot()
      Description copied from interface: PortInstance
      Returns a snapshot that reflects a point-in-time of this port instance.
      Specified by:
      getSnapshot in interface PortInstance
      Returns:
      a snapshot of the port instance

    • isDataPort

      boolean isDataPort()
      Does this represent a port of potentially large data (i.e. record port) as opposed to a model port? Currently, this returns true iff the port is a record port.
      Returns:
      whether this is a record port.
