- com.ctc.wstx.util.ElementId

public final class ElementId extends java.lang.Object
Simple container Object used to store information about id attribute values, and references to such (as of yet undefined) values.Instances can be in one of 2 modes: either in fully defined mode, in which case information refers to location where value was defined (ie. we had id as a value of ID type attribute); or in undefined mode, in which case information refers to the first reference.
Note: this class is designed to be used with
ElementIdMap
, and as a result has some information specifically needed by the map implementation (such as collision links).
