SearchService.Request

参数

返回值

ISearchList 搜索项目的异步列表。

描述

执行搜索请求，该请求将异步获取搜索结果。

以下示例执行查询并使用 EditorApplication.update 在多个帧上打印结果。

[MenuItem("Examples/SearchService/Request List")]
public static void RequestList()
{
    ISearchList results = SearchService.Request("*.cs");

    // It is important to note that when you request some search results,
    // that you need to enumerate them asynchronously using the returned search list.
    AsyncResultEnumerator.Fetch(results, item => Debug.Log(item));
}

struct AsyncResultEnumerator
{
    private Action<SearchItem> m_OnEnumerate;
    private IEnumerator<SearchItem> m_Iterator;

    public static AsyncResultEnumerator Fetch(ISearchList results, Action<SearchItem> onEnumerate)
    {
        return new AsyncResultEnumerator(results, onEnumerate);
    }

    public AsyncResultEnumerator(ISearchList results, Action<SearchItem> onEnumerate)
    {
        m_OnEnumerate = onEnumerate;
        m_Iterator = results.GetEnumerator();
        EditorApplication.update += EnumerateResults;
    }

    private void EnumerateResults()
    {
        if (m_Iterator == null || !m_Iterator.MoveNext())
        {
            m_Iterator = null;
            EditorApplication.update -= EnumerateResults;
        }
        else if (m_Iterator.Current != null)
            m_OnEnumerate(m_Iterator.Current);
    }
}

如果您正在运行协程，您可以像下面这样生成结果

public static IEnumerable<SearchItem> YieldResults()
{
    ISearchList results = SearchService.Request("*.cs");
    foreach (var result in results)
        yield return result;
}

参数

描述

执行搜索请求，并在所有结果都可用时回调指定的函数。

[MenuItem("Examples/SearchService/Request All")]
public static void RequestAll()
{
    SearchService.Request("t:texture", (SearchContext context, IList<SearchItem> items) =>
    {
        Debug.Log("All Textures");
        foreach (var item in items)
            Debug.Log(item);
    }, SearchFlags.Debug);
}

参数

描述

执行搜索请求并为每一批传入的结果回调。可能会获取重复项，因此如果需要，请过滤最终列表。

[MenuItem("Examples/SearchService/Request Async")]
public static void RequestAsync()
{
    var batchCount = 0;
    var totalItemCount = 0;

    void OnIncomingResults(SearchContext context, IEnumerable<SearchItem> items)
    {
        var batchItemCount = items.Count();
        totalItemCount += batchItemCount;
        Debug.Log($"#{++batchCount} Incoming materials ({batchItemCount}): {string.Join("\n", items)}");
    }

    void OnSearchCompleted(SearchContext context)
    {
        Debug.Log($"Query <b>\"{context.searchText}\"</b> completed with a total of {totalItemCount}");
    }

    SearchService.Request("t:material", OnIncomingResults, OnSearchCompleted, SearchFlags.Debug);
}
