From: ockham_at_[hidden]
Date: 2007-10-10 18:21:52
Author: bernhard.reiter
Date: 2007-10-10 18:21:51 EDT (Wed, 10 Oct 2007)
New Revision: 39912
URL: http://svn.boost.org/trac/boost/changeset/39912
Log:
* output_cursor_iterator_wrapper:
Add more comments, change implementation to work with a pointer
(instead of a reference) to an output iterator.
* Re-organise some test files (mainly algorithm-related ones).
Added:
sandbox/SOC/2006/tree/trunk/libs/tree/test/subtree_algorithms_test.cpp (contents, props changed)
sandbox/SOC/2006/tree/trunk/libs/tree/test/test_tree_traversal_data.hpp (contents, props changed)
