generic <typename T>
 where T : System::Linq::Expressions::Expression System::Collections::ObjectModel::ReadOnlyCollection<T> ^ VisitAndConvert(System::Collections::ObjectModel::ReadOnlyCollection<T> ^ nodes, System::String ^ callerName);
public System.Collections.ObjectModel.ReadOnlyCollection<T> VisitAndConvert<T> (System.Collections.ObjectModel.ReadOnlyCollection<T> nodes, string callerName) where T : System.Linq.Expressions.Expression;

member this.VisitAndConvert : System.Collections.ObjectModel.ReadOnlyCollection<'T (requires 'T :> System.Linq.Expressions.Expression)> * string -> System.Collections.ObjectModel.ReadOnlyCollection<'T (requires 'T :> System.Linq.Expressions.Expression)> (requires 'T :> System.Linq.Expressions.Expression)
Public Function VisitAndConvert(Of T As Expression) (nodes As ReadOnlyCollection(Of T), callerName As String) As ReadOnlyCollection(Of T)

Type Parameters

T

The type of the expressions.

Parameters

nodes
ReadOnlyCollection<T>

The expressions to visit.

callerName
String

The name of the calling method; used to report a better error message.

Returns

ReadOnlyCollection<T>

The modified expression collection, if any expression was modified; otherwise, returns the original expression collection.

Exceptions
