    java.io.Serializable, java.util.Comparator

    public class AlphanumericComparer
    extends java.lang.Object
    implements java.util.Comparator, java.io.Serializable
    A Comparer that treats strings as an alternating sequence of alpha parts and numeric parts. The alpha parts are compared using a base collation supplied as a parameter; the numeric parts are compared numerically. "Numeric" here means a sequence of consecutive ASCII digits 0-9.
