Class FetchPlanState

  • Direct Known Subclasses:

    public class FetchPlanState
    extends Object
    Holder for the state control for FetchPlan processing. Maintains a list of the member names being fetched. The first item in the List will be the root. When a new branch of the graph is processed the member name is added, and it is removed once it has been processed. This provides a means of always knowing the depth in the current graph, and also of allowing detection of recursion of member names.
