Adding New Semiconductor Patterns

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

Similarity Calculators
