如何使用Clojure记录实现这个通用Java接口?

我正在努力实施 org.joda.time.ReadableInstant 它继承自通用接口,但显然这不重要。 The interface 是:

public interface ReadableInstant extends Comparable<ReadableInstant> {
    long getMillis();
    Chronology getChronology();
    DateTimeZone getZone();
    int get(DateTimeFieldType type);
    boolean isSupported(DateTimeFieldType field);
    Instant toInstant();
    boolean isEqual(ReadableInstant instant);
    boolean isAfter(ReadableInstant instant);
    boolean isBefore(ReadableInstant instant);
    boolean equals(Object readableInstant);
    int hashCode();
    String toString();
}

我的记录:

(defrecord WeirdDate [year month day]
    ReadableInstant
    (^boolean equals  [this ^Object readableInstant] (.equals (as-date this) readableInstant))
    (^int get [this ^DateTimeFieldType type] (get (as-date this) type))
    (^Chronology getChronology [this] (.getChronology (as-date this)))
    (^long getMillis [this] (.getMillis (as-date this)))
    (^DateTimeZone getZone [this] (.getZone (as-date this)))
    (^int hashCode [this] (.hashCode (as-date this)))
    (^boolean isAfter [this ^ReadableInstant instant] (.isAfter (as-date this) instant))
    (^boolean isBefore [this ^ReadableInstant instant] (.isBefore (as-date this) instant))
    (^boolean isEqual [this ^ReadableInstant instant] (.isEqual (as-date this) instant))
    (^boolean isSupported [this ^DateTimeFieldType field] (.isSupported (as-date this) field))
    (^Instant.toInstant [this] (.toInstant (as-date this)))
    (^String toString [this] (.toString (as-date this))))

但我得到了错误:

java.lang.IllegalArgumentException: Must hint overloaded method: get

我的类型提示错误吗?还有其他问题吗?

(向您在 Clojure mailing list where I've already asked a longer version of this question ,我认为这里的一个简短问题可能更容易回答)
