- scoped pathsearch for term
An XPath specification that provides an easy way to access data from your Web applications. exteNd Director includes a group of predefined scoped paths that are available from the Page Flow and Workflow Modelers and through the scoped path API.Scoped paths combine the concepts of application scope and physical location. Application scope refers to the state of the data, or data persistence. Data is nonpersistent if it is available to a single user for a single session. Data is persistent if it is available to one or more users over multiple sessions, and potentially to external applications. A scope also defines what application objects can access data. For example, exteNd Director defines a Flow scoped path that is accessible to any object in a given PageFlow or Workflow.A path is the physical location of the data. exteNd Director defines a path syntax for a set of predefined scoped paths. This syntax is based on XPath and includes support for XPath expressions and functions.
