|
We need experienced review managers. Please take a look at the list
|
|
of libraries in need of managers and check out their descriptions. In
|
|
general review managers are active boost participants or library
|
|
contributors. If you can serve as review manager for any of them,
|
|
email Ron Garcia or John Phillips, "garcia at cs dot indiana dot edu"
|
|
and "jphillip at capital dot edu" respectively.
|
|
|
|
A link to this report will be posted to www.boost.org.
|
|
If you would like us to make any modifications or additions to this
|
|
report before we do that, please email Ron or John.
|
|
|
|
If you're library author and plan on submitting a library for review
|
|
in the next 3-6 months, send Ron or John a short description of your
|
|
library and we'll add it to the Libraries Under Construction below.
|
|
We know that there are many libraries that are near completion, but we
|
|
have hard time keeping track all of them. Please keep us informed
|
|
about your progress.

|
:Description:
|
|
The purpose of this library is to free designers of
|
|
exception classes from having to consider what data needs to be
|
|
stored in exception objects in order for the catch site to be
|
|
able to make sense of what went wrong.
|
|
|
|
When the exception class is used, arbitrary values can be stored
|
|
in any exception. This can be done directly in the
|
|
throw-expression, or at a later time as the exception object
|
|
propagates up the call stack. The ability to add data to any
|
|
exception object after it has been thrown is important, because
|
|
often some of the information needed to handle an exception is
|
|
unavailable at the time of the throw.

:Description:
|
|
|
|
The Boost.FSM library is an implementation of FSM (stands for
|
|
Finite State Machine) programming concept. The main goals of the
|
|
library are:
|
|
|
|
* Simplicity. It should be very simple to create state machines using
|
|
this library.
|
|
* Performance. The state machine infrastructure should not be
|
|
very time and memory-consuming in order to be applicable in
|
|
more use cases.
|
|
* Extensibility. A developer may want to add more states to an
|
|
existing state machine. A developer should also be able to
|
|
specify additional transitions and events for the machine with
|
|
minimum modifications to the existing code.

|
|
:Description: The Floating Point Utilities library contains the following:
|
|
|
|
* Floating point number classification functions: fpclassify, isfinite,
|
|
isinf, isnan, isnormal (Follows TR1)
|
|
* Sign bit functions: signbit, copysign, changesign (Follows TR1)
|
|
* Facets that format and parse infinity and NaN according to the C99
|
|
standard. (These can be used for portable handling of infinity and NaN
|
|
in text streams.)

:Description:
|
|
The built in C/C++ switch statement is very efficient. Unfortunately,
|
|
unlike a chained if/else construct there is no easy way to use it when
|
|
the number of cases depends on a template parameter. The Switch library
|
|
addresses this issue.

:Description:
|
|
A number of additions and modifications to the Property Map Library,
|
|
including:
|
|
|
|
* A constant-valued property map, useful for naturally unweighted
|
|
graphs.
|
|
* A noop-writing property map, useful when you have to provide an
|
|
argument, but just don't care about the output.
|
|
* See

`ChangeLog <http://svn.boost.org/trac/boost/browser/sandbox/graph-v2/libs/property_map/ChangeLog>`__

|
:Description:
|
|
A number of additions and modifications to the Graph Library,
|
|
including:
|
|
|
|
* Two new graph classes (undirected and directed) which are intended
|
|
to make the library more approachable for new developers
|
|
* A suite of graph measures including degree and closeness
|
|
centrality, mean geodesic distance, eccentricity, and clustering
|
|
coefficients.
|
|
* An algorithm for visiting all cycles in a directed graph (Tiernan's
|
|
from 1970ish). It works for undirected graphs too, but reports cycles
|
|
twice (one for each direction).
|
|
* An algorithm for visiting all the cliques a graph (Bron&Kerbosch).
|
|
Works for both directed and undirected.
|
|
* Derived graph measures radius and diameter (from eccentricity) and
|
|
girth and circumference (from Tiernan), and clique number (from
|
|
Bron&Kerbosch).
|
|
* An exterior_property class that helps hides some of the weirdness
|
|
with exterior properties.
|
|
* runtime and compile-time tests for the new algorithms.
|
|
* a substantial amount of documentation
|
|
* Graph cores, implemented by David Gleich (@Stanford University)
|
|
* Deterministic graph generators - capable of creating or inducing
|
|
specific types of graphs over a vertex set (e.g., star graph, wheel
|
|
graph, prism graph, etc). There are several other specific types that
|
|
could be added to this, but I haven't had the time just yet.

Libraries under development

===========================

|
Dataflow
|
|
--------
|
|
:Author: Stjepan Rajko
|
|
|
|
:Description:
|
|
The Dataflow library provides generic support for data
|
|
producers, consumers, and connections between the two. It also
|
|
provides layers for several specific dataflow mechanisms, namely
|
|
Boost.Signals, VTK data/display pipelines, and plain
|
|
pointers. The Dataflow library came out of the Signal Network
|
|
GSoC project, mentored by Doug Gregor.
|
|
|
|
:Status:
|
|
I am polishing the Dataflow library for submission, and am expecting
|
|
to add it to the review queue in the next couple of months.
|
|
I am currently ironing out some faults in the design of the library,
|
|
filling in missing features, and testing it on / adapting it to
|
|
different dataflow mechanisms (currently VTK and soon
|
|
Boost.Iostreams). As soon as I'm pretty sure that things are going
|
|
the right way, I'll submit this to the review queue while I do the
|
|
finishing touches.

Constrained Value

|
|
|
|
:Description:
|
|
The Constrained Value library contains class templates
|
|
useful for creating constrained objects. The simplest example
|
|
of a constrained object is hour. The only valid values for an hour
|
|
within a day are integers from the range [0, 23]. With this library,
|
|
you can create a variable which behaves exactly like int, but does
|
|
not allow for assignment of values which do not belong to the
|
|
allowed range. The library doesn't focus only on constrained
|
|
objects that hold a value belonging to a specified range (i.e.,
|
|
bounded objects). Virtually any constraint can be imposed using
|
|
appropriate predicate. You can specify what happens in case of
|
|
assignment of an invalid value, e.g. an exception may be thrown or
|
|
the value may be adjusted to meet the constraint criterions.
|
|
|
|
:Status: I'm planning to finish it in 1-2 months.
