최근에 현재 가지고있는 복잡한 문제를 해결할 js (harmony) weakmap 지원을 보았습니다. luckly 꽤 심한 브라우저 지원을 제공하는 shim (https://github.com/Benvie/WeakMap)이 GWT 래퍼 구현으로 도약했습니다.GWT에서 WeakMap 래퍼 구현 만들기 - 오류 발생
나는 이것이 매우 단순해야한다고 느꼈지만, 나의 단위 테스트는 오류를 던지고있다.
다음내 GWT 클래스입니다 : 여기
public class WeakMapTest extends GWTTestCase {
@Override
public String getModuleName() {
return "com.jorsek.util.Util";
}
@Test
public void testWeakMap(){
WeakMap<SomeObject, SomeObject> map = new WeakMap<SomeObject, SomeObject>();
SomeObject key = new SomeObject("KEY");
SomeObject value = new SomeObject("VALUE");
map.set(key, value);
assertEquals(map.get(key).getValue(), value.getValue());
}
private class SomeObject {
private final String value;
public SomeObject(String value){
this.value = value;
}
private String getValue() {
return value;
}
}
}
public class WeakMap<K, V> {
protected JavaScriptObject nativeWeakMap;
public WeakMap(){
setup();
}
native void setup()/*-{
[email protected]::nativeWeakMap = new $wnd.WeakMap;
}-*/;
public void set(K key, V value){
nativeSet(key, value);
}
native void nativeSet(K key, V value)/*-{
var nativeMap = [email protected]::nativeWeakMap;
nativeMap.set(key, value);
}-*/;
public V get(K key){
return nativeGet(key);
}
native V nativeGet(K key)/*-{
var nativeMap = [email protected]::nativeWeakMap;
nativeMap.get(key);
}-*/;
}

:
- 내가 자바 스크립트가 올바르게 포함되고 확신 셋업() 메소드가 제대로 weakmap 객체를 만들고 자바 스크립트 객체입니다 nativeWeakMap에 할당
- (나는 충분히 알고 그 부분을 완료했습니다). 나는 이것이 null이 아니라는 것을 알기 때문에 이것을 표준 출력으로 출력 할 수있다.
아이디어가 있으십니까? 이것은 GWT에 큰 도움이 될 것입니다!
