Class DexpiMappingLoader

java.lang.Object

neqsim.process.processmodel.dexpi.DexpiMappingLoader

public final class DexpiMappingLoader
extends Object

Loads DEXPI-to-NeqSim equipment and piping component mappings from properties files on the classpath.

The mapping files are located at:

• neqsim/process/processmodel/dexpi_equipment_mapping.properties
• neqsim/process/processmodel/dexpi_piping_component_mapping.properties

Each properties file maps a DEXPI ComponentClass string (e.g. "CentrifugalPump") to a EquipmentEnum name (e.g. "Pump"). If a properties file cannot be loaded, the loader falls back to a built-in default mapping.

Method Details

loadEquipmentMapping

public static Map<String, EquipmentEnum> loadEquipmentMapping()

Loads the DEXPI equipment class to NeqSim EquipmentEnum mapping from the classpath properties file.

Returns:

an unmodifiable map from DEXPI ComponentClass to EquipmentEnum

loadPipingComponentMapping

public static Map<String, EquipmentEnum> loadPipingComponentMapping()

Loads the DEXPI piping component class to NeqSim EquipmentEnum mapping from the classpath properties file.

Returns:

an unmodifiable map from DEXPI ComponentClass to EquipmentEnum

clearCache

public static void clearCache()

Clears the cached mappings so they will be reloaded on next access. Useful for testing.

loadMapping

private static Map<String, EquipmentEnum> loadMapping(String resourcePath,
 String label)

Loads a mapping from a properties file on the classpath.

Parameters:

resourcePath - the classpath resource path

label - a descriptive label for logging

Returns:

an unmodifiable map from DEXPI class name to EquipmentEnum
