Class GraphQlQueryableAsyncExtensions

Namespace

BpNexT.NET.GraphQL.Queryable

Assembly

BpNexT.NET.GraphQL.dll

Async terminal operators for GraphQL-backed queries. Each operator builds the same expression tree its synchronous Queryable counterpart would produce and executes it through the provider's async pipeline, so query translation (rowRead/rowsRead/conRead selection, filter splitting) is identical to the sync path.

GraphQlQueryableAsyncExtensions

Methods

AllAsync<T>(IQueryable<T>, Expression<Func<T, bool>>, CancellationToken)

Asynchronously determines whether all elements match the predicate.
