Class DexpiEquipmentFactory

java.lang.Object
neqsim.process.processmodel.dexpi.DexpiEquipmentFactory
public final class DexpiEquipmentFactory extends Object
Factory that converts DexpiProcessUnit placeholders into runnable NeqSim process equipment by matching the EquipmentEnum type and applying sizing attributes from DEXPI GenericAttributes.

This factory is used by DexpiSimulationBuilder during the topology walk to instantiate real equipment objects (Separator, Compressor, Valve, etc.) from the DEXPI import placeholders.

    • create

      public static ProcessEquipmentInterface create(DexpiProcessUnit unit, StreamInterface inletStream)
      Creates a runnable NeqSim equipment instance from a DEXPI process unit and its inlet stream.

      The method selects the correct NeqSim equipment class based on DexpiProcessUnit.getMappedEquipment(), wires the inlet stream, and applies any sizing attributes (diameter, length, Cv, etc.) extracted from the DEXPI XML.

      Parameters:
      unit - the DEXPI process unit placeholder
      inletStream - the inlet stream to wire to the equipment (may be null for Mixer)
      Returns:
      a fully configured NeqSim process equipment instance, or a pass-through Stream if the equipment type is not supported
