Class NSStringCompareOptions

  • public final class NSStringCompareOptions
extends java.lang.Object
    These options apply to the various search/find and comparison methods (except where noted).

    • Field Summary

      Fields 
      Modifier and Type Field Description
      static long AnchoredSearch
      Search is limited to start (or end, if NSBackwardsSearch) of source string
      static long BackwardsSearch
      Search from end of source string
      static long CaseInsensitiveSearch  
      static long DiacriticInsensitiveSearch
      If specified, ignores diacritics (o-umlaut == o)
      static long ForcedOrderingSearch
      If specified, comparisons are forced to return either NSOrderedAscending or NSOrderedDescending if the strings are equivalent but not strictly equal, for stability when sorting (e.g.
      static long LiteralSearch
      Exact character-by-character equivalence
      static long NumericSearch
      Added in 10.2; Numbers within strings are compared using numeric value, that is, Foo2.txt < Foo7.txt < Foo25.txt; only applies to compare methods, not find
      static long RegularExpressionSearch
      Applies to rangeOfString:..., stringByReplacingOccurrencesOfString:..., and replaceOccurrencesOfString:... methods only; the search string is treated as an ICU-compatible regular expression; if set, no other options can apply except NSCaseInsensitiveSearch and NSAnchoredSearch
      static long WidthInsensitiveSearch
      If specified, ignores width differences ('a' == UFF41)
