I am having a hard time understanding the use of iterator in wxlua.
I guess an iterator is created by wxString::const_iterator end() or
wxString::const_iterator begin() for wxString which would be coded
wx.wxString(str):end() but end is a reserve word in Lua. I guess end could be
renamed.
the code would be
date:ParseDate(aa, wx.wxString_const_iterator(aa:end()) )
since aa:end()returns a wxString_iterator
Note: that using begin() give unexpected results
aa = wx.wxString("09-06-2012")
print(date:ParseDate(aa, wx.wxString_const_iterator(aa:begin())))
aa = wx.wxString("")
print(date:ParseDate(aa, wx.wxString_const_iterator(aa:begin())))
display:
true
false
I would have expected both of these to be identical.
--------------------------------------------------------
Are iterators useful in wxLua? The addition in wxWidget maybe justified for
saving copying of strings in a tight loop but most of the time C++ programmer
will replace their code in the following way and live with the overhead.
old code: foo(v)
new code: foo(v,&(type::const_iterator)v.end) // would not compile purely for
illustration.
In wxLua using foo(v) or foo(string.match(v,pattern)) seems so much simpler
than
using an iterator.
ParseDate is not the only function using iterator but all of them seem similar.
Thank you.
