Typescript LanguageService不提供数组类型的自动完成信息

Question

我已经为Typescript LanguageService (https://github.com/BestSolution-at/java2typescript)实现了一个java桥，它工作起来非常流畅，但我遇到了以下问题。

让我们假设我有以下类型的文件(sample.ts)

class Person {
    firstname : string;
    lastname : string;
    friendList : Person[];

    constructor(firstname : string, lastname : string) {
        this.firstname = firstname;
        this.lastname = lastname;
    }

    public getName() {
        return this.lastname + ", " + this.firstname;
    }

    public getFirstname() {
        return this.firstname;
    }
}

var p : Person = new Person("Tom","Schindl");
p.

执行以下Java代码(接口同LanguageService接口)：

CompletionInfo info = service.getCompletionsAtPosition(fileId, 424);
info.entries().stream().forEach( i -> {
  service.getCompletionEntryDetails(fileId, 424, i.name());
});

为我提供以下信息(编码为JSON)：

{
  "requestIdRef": 4,
  "result": {
    "name": "firstname",
    "kindModifiers": "",
    "kind": "property",
    "displayParts": [
      {
        "text": "(",
        "kind": "punctuation"
      },
      {
        "text": "property",
        "kind": "text"
      },
      {
        "text": ")",
        "kind": "punctuation"
      },
      {
        "text": " ",
        "kind": "space"
      },
      {
        "text": "Person",
        "kind": "className"
      },
      {
        "text": ".",
        "kind": "punctuation"
      },
      {
        "text": "firstname",
        "kind": "propertyName"
      },
      {
        "text": ":",
        "kind": "punctuation"
      },
      {
        "text": " ",
        "kind": "space"
      },
      {
        "text": "string",
        "kind": "keyword"
      }
    ],
    "documentation": [

    ]
  }
}

..。

{
  "requestIdRef": 6,
  "result": {
    "name": "friendList",
    "kindModifiers": "",
    "kind": "property",
    "displayParts": [
      {
        "text": "(",
        "kind": "punctuation"
      },
      {
        "text": "property",
        "kind": "text"
      },
      {
        "text": ")",
        "kind": "punctuation"
      },
      {
        "text": " ",
        "kind": "space"
      },
      {
        "text": "Person",
        "kind": "className"
      },
      {
        "text": ".",
        "kind": "punctuation"
      },
      {
        "text": "friendList",
        "kind": "propertyName"
      },
      {
        "text": ":",
        "kind": "punctuation"
      },
      {
        "text": " ",
        "kind": "space"
      },
      {
        "text": "{",
        "kind": "punctuation"
      },
      {
        "text": "}",
        "kind": "punctuation"
      }
    ],
    "documentation": [

    ]
  }
}

正如您注意到的，具有内置类型的属性的完成细节是有效的(displayParts中的最后一段)，而对于自定义类型，我没有得到任何信息。

由于VS-Code正在显示它必须可用的信息，奇怪的是，在查看他们的代码时，他们发出的LanguageService调用与我相同(https://github.com/Microsoft/vscode/blob/master/src/vs/languages/typescript/common/features/suggestions.ts)。

回答我自己的问题:我忘记预先加载lib.d.ts。加载lib.d.ts解决了这个问题！
