 virtual bool ProcessConstraint(System::Web::HttpContextBase ^ httpContext, System::Object ^ constraint, System::String ^ parameterName, System::Web::Routing::RouteValueDictionary ^ values, System::Web::Routing::RouteDirection routeDirection);
protected virtual bool ProcessConstraint(System.Web.HttpContextBase httpContext, object constraint, string parameterName, System.Web.Routing.RouteValueDictionary values, System.Web.Routing.RouteDirection routeDirection);
abstract member ProcessConstraint : System.Web.HttpContextBase * obj * string * System.Web.Routing.RouteValueDictionary * System.Web.Routing.RouteDirection -> bool
override this.ProcessConstraint : System.Web.HttpContextBase * obj * string * System.Web.Routing.RouteValueDictionary * System.Web.Routing.RouteDirection -> bool
Protected Overridable Function ProcessConstraint (httpContext As HttpContextBase, constraint As Object, parameterName As String, values As RouteValueDictionary, routeDirection As RouteDirection) As Boolean
