Class SortKeyDefinition


  • public class SortKeyDefinition
    extends java.lang.Object
    A SortKeyDefinition defines one component of a sort key.
    Note that most attributes defining the sort key can be attribute value templates, and can therefore vary from one invocation to another. We hold them as expressions, but optimise for the case where the attributes are all fixed strings: in this case we can use the same Comparer object each time.
