TCollection_HExtendedString Class Reference

A variable-length sequence of "extended" (UNICODE) characters (16-bit character type). It provides editing operations with built-in memory management to make ExtendedString objects easier to use than ordinary extended character arrays. HExtendedString objects are handles to strings. More...
