@class wxArrayString
@wxheader{arrstr.h}
(wxArrayString uses its knowledge of internals of wxString class to achieve this).
This class is used in the same way as other dynamic arrays(), except that no
- @e WX_DEFINE_ARRAY declaration is needed for it.
+ ::WX_DEFINE_ARRAY declaration is needed for it.
When a string is added or inserted in the array, a copy of the string is created,
so the original string may be safely deleted (e.g. if it was a @e wxChar *
pointer the memory it was using can be freed immediately after this).
array.Last().MakeUpper();
@endcode
- There is also a variant of wxArrayString called wxSortedArrayString which has
- exactly the same methods as wxArrayString, but which always keeps the string
- in it in (alphabetical) order. wxSortedArrayString uses binary search in its
- wxArrayString::Index() function (instead of linear search for wxArrayString::Index())
- which makes it much more efficient if you add strings to the array rarely
- (because, of course, you have to pay for Index() efficiency by having Add() be
- slower) but search for them often. Several methods should not be used with
- sorted array (basically, all which break the order of items) which is
- mentioned in their description.
-
@note none of the methods of wxArrayString is virtual including its
destructor, so this class should not be used as a base class.
a specialization of wxArray class for the wxString member data: it is not
implemented like this, but it does have all of the wxArray functions.
