Package neqsim.process.processmodel.dexpi

package neqsim.process.processmodel.dexpi

DEXPI integration layer for importing and exporting P&ID data.

This package provides utilities for working with DEXPI (Data Exchange in the Process Industry) XML files, enabling round-trip import and export of process flow diagrams.

Key Components

• DexpiXmlReader - Import DEXPI P&ID XML to ProcessSystem
• DexpiXmlWriter - Export ProcessSystem to DEXPI XML
• DexpiProcessUnit - Lightweight placeholder for imported equipment
• DexpiStream - Runnable stream with DEXPI metadata
• DexpiMetadata - Shared constants for DEXPI exchanges
• DexpiRoundTripProfile - Validation for round-trip fidelity

Usage Example

// Import from DEXPI XML
ProcessSystem process = DexpiXmlReader.read(new File("plant.xml"), templateStream);

// Access imported equipment
DexpiProcessUnit pump = (DexpiProcessUnit) process.getUnit("P-101");
EquipmentEnum type = pump.getMappedEquipment();

// Export back to DEXPI XML
DexpiXmlWriter.write(process, new File("export.xml"));
