Solicite propostas de todos os dados caret aplicáveis ProposalSourceBasee completionState. Permita groupingDelay passar do primeiro ProposalSourceBase para concluir antes de desistir das outras fontes.

public abstract Microsoft.VisualStudio.Threading.AsyncQueue<Microsoft.VisualStudio.Language.Proposals.ProposalCollectionBase> RequestProposals(Microsoft.VisualStudio.Text.VirtualSnapshotPoint caret, Microsoft.VisualStudio.Language.Proposals.CompletionState? completionState, Microsoft.VisualStudio.Language.Proposals.ProposalScenario scenario, char triggeringCharacter, TimeSpan groupingDelay, System.Threading.CancellationToken cancel);

abstract member RequestProposals : Microsoft.VisualStudio.Text.VirtualSnapshotPoint * Microsoft.VisualStudio.Language.Proposals.CompletionState * Microsoft.VisualStudio.Language.Proposals.ProposalScenario * char * TimeSpan * System.Threading.CancellationToken -> Microsoft.VisualStudio.Threading.AsyncQueue<Microsoft.VisualStudio.Language.Proposals.ProposalCollectionBase>

Public MustOverride Function RequestProposals (caret As VirtualSnapshotPoint, completionState As CompletionState, scenario As ProposalScenario, triggeringCharacter As Char, groupingDelay As TimeSpan, cancel As CancellationToken) As AsyncQueue(Of ProposalCollectionBase)

Parâmetros

caret: VirtualSnapshotPoint

completionState: CompletionState

scenario: ProposalScenario

triggeringCharacter: Char

groupingDelay: TimeSpan

cancel: CancellationToken

Retornos

AsyncQueue<ProposalCollectionBase>

Um AsyncQueue<T> de ProposalCollectionBases. Complete() será chamado na fila quando todos os ProposalSourceBases tiverem sido concluídos.

Comentários

O algoritmo para enfileirar propostas é o seguinte:

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.
