public abstract @interface TypeConverter
implements Annotation


Marks a method as a type converter. A class can have as many @TypeConverter methods as it needs.

Each converter method should receive 1 parameter and have non-void return type.

 // example converter for java.util.Date
 public static class Converters {
    public Date fromTimestamp(Long value) {
        return value == null ? null : new Date(value);

    public Long dateToTimestamp(Date date) {
        if (date == null) {
            return null;
        } else {
            return date.getTime();
