Class BindingSetContextObject

  • public class BindingSetContextObject
extends java.lang.Object
    This is the velocity context object, that represents a concrete BindingSet in phase 2 (@see SQLEngine) From its constructor parameters it already knows, which binding items will be requested from it and this allows it to determine the right concrete BindingSet for its name Also it keeps track of all requested BindingItems to find the right BindingSet for the BindingSet name and to provide the caller with information about used BindingItems
