Adding New Inductor Patterns
- In the manufacturer handler's
initializePatterns():
registry.addPattern(ComponentType.INDUCTOR, "^NEWIND[0-9]{4}.*");
registry.addPattern(ComponentType.INDUCTOR_CHIP_MANUFACTURER, "^NEWIND[0-9]{4}.*");
- Add to
getSupportedTypes():
types.add(ComponentType.INDUCTOR);
types.add(ComponentType.INDUCTOR_CHIP_MANUFACTURER);
