          • Visits a NodeArray using the supplied visitor, possibly returning a new NodeArray in its place.

            • If the input node array is undefined, the output is undefined.
            • If the visitor can return undefined, the node it visits in the array will be reused.
            • If the output node array is not undefined, then its contents will satisfy the test.
            • In order to obtain a return type that is more specific than NodeArray<Node>, a test function must be provided, and that function must be a type predicate.

            Type Parameters

            Parameters

            • nodes: TInArray

              The NodeArray to visit.

            • visitor: Visitor<TIn, tsc.Node | undefined>

              The callback used to visit a Node.

            • test: (node: tsc.Node) => node is TOut

              A node test to execute for each node.

            • Optionalstart: number

              An optional value indicating the starting offset at which to start visiting.

            • Optionalcount: number

              An optional value indicating the maximum number of nodes to visit.

            Returns NodeArray<TOut> | TInArray & undefined
