TypeTree
========
This is the 2.6.0-rc1 version of the TypeTree library for statically typed object trees.
TypeTree 2.6.0-rc1 is compatible with the 2.6.0 release of the DUNE core modules and
the 2.6.0 release of PDELab.
Changes
=======
TypeTree 2.6
------------
- TypeTree has updated its minimum build toolchain requirements. You now need a compiler that is at
least compatible with GCC 5 in C++14 mode and CMake 3.1.0.
- There is a new, simpler way of applying a functor to each tree node that keeps you from having
to write a visitor by yourself, e.g.:
```c++
int i = 0;
forEachNode(tree, [](auto&&... node) {
++i;
});
```
Thanks to Carsten Gräser for contributing this feature!
TypeTree 2.5
------------
- TypeTree has updated its minimum compiler requirements. You now need a compiler that is at
least compatible with GCC 4.9 in C++14 mode.
- Removed support for Autotools.
TypeTree 2.4
------------
- TypeTree has updated its minimum compiler requirements. You now need a compiler that is at
least compatible with GCC 4.7 in C++11 mode.
- A lot of compatibility code for older compilers has been removed. In particular, the old
CompositeNode with a fixed number of children has been removed and the old VariadicCompositeNode
has been renamed to CompositeNode.
- As part of these changes, we were able to remove libdunetypetree, so TypeTree is now a header-only
library. Thanks, Ansgar!
- In addition to the `DynamicTreePath` and the fully static `TreePath`, there is now a `HybridTreePath`,
which allows users to use a runtime index in some places of the path and a compile time index at others.
- As part of this new `HybridTreePath`, there is a backport of the C++14 index_sequence to C++11 in the namespace
`Dune::TypeTree::Std`. Moreover, there is an `index_constant<i>`, which is an alias template for
`std::integral_constant<std::size_t,i>`, and a number of predefined `constexpr` objects `Dune::TypeTree::Indices::_0`
etc, which are just `index_constant`s of the specified value. These exist up to the index 19 for now.
- Based on the new `HybridTreePath` and those `index_constant`s, there is now a much more user-friendly way of
extracting child nodes: All interior nodes now have a method `child()` which accepts either
- a sequence of integers and `index_constant`s
- a `HybridTreePath`
- a `TreePath`
and returns the subtree rooted at that path. There is also a freestanding function `child(node,path)`, which should be
used in generic algorithm code as it is more robust (it can e.g. deal correctly with an empty path).
- The old child extraction using `extract_child()` has been deprecated.
- Lots of smaller fixes
- Release history
- TypeTree 2.4.0
- Fix rendering of links in README
- TypeTree 2.4.0-rc1
- Initial release candidate
TypeTree 2.3
------------
This release only contains minor changes to fix buildsystem issues and fix a number of
bugs.
- Full support for CMake (thanks to Christoph and Markus!).
- Fixes to Autotools tests.
- Resolved some compilation problems on older compilers.
- Release history
TypeTree 2.3.1
- Release without further changes
TypeTree 2.3.1-rc1
- Small fixes to included headers and documentation
TypeTree 2.3.0
- Skipped because version 2.3.1 of the core modules was released in the meantime
and it was considered better to keep the version numbers in sync
TypeTree 1.0
------------
This is the initial standalone release. It only contains changes due to the extraction
from the PDELab sources.
- Moved headers from dune/pdelab/common/typetree/ to dune/typetree/.
- Changed namespace from Dune::PDELab::TypeTree to Dune::TypeTree.
- Moved tests to top-level directory tests/.
