Class DexpiXmlWriter

java.lang.Object

neqsim.process.processmodel.dexpi.DexpiXmlWriter

public final class DexpiXmlWriter
extends Object

Utility for exporting ProcessSystems created from DEXPI data back into a lightweight DEXPI XML representation.

The writer groups all discovered DexpiStream segments by line number (or fluid code when a line is not available) to generate simple <PipingNetworkSystem> elements with associated <PipingNetworkSegment> children.
