Enum in Java
1. Enum Class
public enum ContainerPropertyConstants { RETAILER("retailer"), LINED("isLined"), BAGGING("bagging"), MISSING("missing"), MOVABLE("movable"), RESERVABLE("reservable"), CONTAINED_DELIVERY_TOTE("hasContainerDeliveryTote"), DAMAGED("isDamaged"), DIRTY("isDirty"), TAINTED("isTainted"), CONTAINED_STOCK("hasContainedStock"), UNKNOWN("unknown"); private String value; private ContainerPropertyConstants(String value) { this.value = value; } public String getValue() { return value; } @Override public String toString() { return this.getValue(); } public static ContainerPropertyConstants getEnum(String propertyKey) { for(ContainerPropertyConstants v : values()) { if(v.getValue().equals(propertyKey.trim())) { return v; } } return UNKNOWN; } }
2. Use Enum Class
private BinAttributes getBinAttributes(Map<PropertyKey, PropertyValue> properties, BinAttributes.Builder builder) { properties.forEach((k, v) -> { switch (ContainerPropertyConstants.getEnum(k.toString())) { case LINED: break; case MOVABLE: builder.setAccessibleToPhoenix(Boolean.valueOf(v.getPropertyValue())); break; case RESERVABLE: break; case CONTAINED_DELIVERY_TOTE: break; case DAMAGED: builder.setDamaged(Boolean.valueOf(v.getPropertyValue())); break; case DIRTY: builder.setContaminated( Boolean.valueOf(v.getPropertyValue())); break; case TAINTED: builder.setTainted(Boolean.valueOf(v.getPropertyValue())); break; case CONTAINED_STOCK: break; case UNKNOWN: throw new IllegalArgumentException("Phoenix container property [" + k + "] not recognised."); default: logger.info("Currently cannot handle container property [{}]", k);
break; } }); return builder.build(); }
