반환
AsyncQueue<T> 의 ProposalCollectionBase입니다. Complete() 는 모든 ProposalSourceBase가 완료되면 큐에서 호출됩니다.
설명
제안을 큐에 추가하기 위한 알고리즘은 다음과 같습니다.
1. Call <xref data-throw-if-not-resolved="true" uid="Microsoft.VisualStudio.Language.Proposals.ProposalSourceBase.RequestProposalsAsync(Microsoft.VisualStudio.Text.VirtualSnapshotPoint,Microsoft.VisualStudio.Language.Proposals.CompletionState,Microsoft.VisualStudio.Language.Proposals.ProposalScenario,System.Char,System.Threading.CancellationToken)"></xref> for each source.
2. Wait until one source returns with a non-null/empty result.
3. Wait an additional <code data-dev-comment-type="paramref">groupingDelay</code> to allow other sources to generate results.
4. Enqueue all sources that generated results using the ordering specified by their <xref data-throw-if-not-resolved="true" uid="Microsoft.VisualStudio.Language.Proposals.ProposalSourceProviderBase"></xref>.
5. Enqueue remaining results in their order of completion.
