Method Detail

### compare

    public int compare(java.lang.Object a,
                       java.lang.Object b)

  Compare two string objects using default collating
  Overrides:
    `compare` in class `Comparer`
  Returns:
    <0 if a<b, 0 if a=b, >0 if a>b
  Throws:
    `java.lang.ClassCastException` - if the objects are of the wrong type for this Comparer

### setCaseOrder

    public Comparer setCaseOrder(int caseOrder)

  Set case order
  Overrides:
    `setCaseOrder` in class `TextComparer`
  Parameters:
    `caseOrder` - one of DEFAULT_CASE_ORDER, LOWERCASE_FIRST, or UPPERCASE_FIRST. Indicates whether upper case letters precede or follow lower case letters in the ordering
  Returns:
    either this or a different Comparer that will be used to perform the comparisons. This allows the TextComparer to delegate the comparison to a Comparer dedicated to a specific case order.
