TypeConverter

public abstract @interface TypeConverter
implements Annotation

androidx.room.TypeConverter


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 {
   @TypeConverter
   public Date fromTimestamp(Long value) {
     return value == null ? null : new Date(value);
   }

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