[Olena-patches] cleanup-2008 2076: Allow delayed construction of function expressions.

https://svn.lrde.epita.fr/svn/oln/branches/cleanup-2008/milena Index: ChangeLog from Thierry Geraud &lt;thierry.geraud(a)lrde.epita.fr&gt; Allow delayed construction of function expressions. * mln/trait/ch_value.hh (mln_ch_value_): New. * mln/pw/cst.hh (cst_): New ctor without arg. * mln/fun/ops.hh (mln_decl_binary_expr_): New ctor wihtout arg so that the definition of expr template functions involved in image types can be delayed. (mln_decl_unary_expr_): Likewise. fun/ops.hh | 16 ++++++++++++---- pw/cst.hh | 10 +++++++++- trait/ch_value.hh | 1 + 3 files changed, 22 insertions(+), 5 deletions(-) Index: mln/trait/ch_value.hh --- mln/trait/ch_value.hh (revision 2075) +++ mln/trait/ch_value.hh (working copy) @@ -38,6 +38,7 @@ # define mln_ch_value(I, V) typename mln::trait::ch_value< I, V >::ret +# define mln_ch_value_(I, V) mln::trait::ch_value< I, V >::ret Index: mln/pw/cst.hh --- mln/pw/cst.hh (revision 2075) +++ mln/pw/cst.hh (working copy) @@ -1,4 +1,4 @@ -// Copyright (C) 2007 EPITA Research and Development Laboratory +// Copyright (C) 2007, 2008 EPITA Research and Development Laboratory // // This file is part of the Olena Library.
