Certaines informations portent sur la préversion du produit qui est susceptible d’être en grande partie modifiée avant sa publication. Microsoft exclut toute garantie, expresse ou implicite, concernant les informations fournies ici.
Demandez des propositions de tous les s applicables ProposalSourceBasedonnés caret et completionState.
Autorisez groupingDelay à passer de la première ProposalSourceBase à la fin avant de renoncer aux autres sources.

ProposalCollectionBasede AsyncQueue<T> s. Complete() est appelé dans la file d’attente lorsque tous les ProposalSourceBases sont terminés.
Remarques
L’algorithme de mise en file d’attente des propositions est le suivant :
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.
