Class GroupId

  • Direct Known Subclasses:
    BucketGroupId, NullId, RootId, ValueGroupId

    public abstract class GroupId
    extends java.lang.Object
    This abstract class represents the id of a single group in the grouping result model. A subclass corresponding to the evaluation result of generating GroupingExpression is contained in all Group objects. It is used by GroupingRequest to identify its root result group, and by all client code for identifying groups.

    The toString() method of this class generates a URI-compatible string on the form "group:<typeName>:<subclassSpecific>".
