Adding New Semiconductor Patterns
- In the manufacturer handler's
initializePatterns():
registry.addPattern(ComponentType.MOSFET, "^NEWMOS[0-9].*");
registry.addPattern(ComponentType.MOSFET_MANUFACTURER, "^NEWMOS[0-9].*");
- Add to
getSupportedTypes():
types.add(ComponentType.MOSFET);
types.add(ComponentType.MOSFET_MANUFACTURER);
