|
|
August 17, 2007 -- Time Series Accepted.
|
|
Announcement: <https://lists.boost.org/boost-announce/2007/08/0142.php>
|
|
July 24, 2007 -- Boost Version 1.34.1 Released.
|
|
This is a bug fix release addressing many problems with
|
|
the 1.34.0 release. Announcement: <http://svn.boost.org/trac/boost/query?status=closed&milestone=Boost+1.34.1>
|
|
|
|
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.

### Exception
|
|
|
|
|
|
| Author: | Emil Dotchevski |

|
| Download: | <http://www.revergestudios.com/boost-exception/boost-exception.zip> |
|
|
| 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. |
|
|
|
|
|
|
### Finite State Machines
|
|

|
|
| 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.

### Floating Point Utilities
|
|
|
|
|
|
| Author: | Johan Råde |
|
|
| Review Manager: | Need Volunteer |
|
|
| Download: | [Boost Sandbox Vault](http://boost-consulting.com/vault/index.php?directory=Math%20-%20Numerics) |
|
|
| 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.)
|
|
|
|

|
|
|
### Switch
|
|
|
|
|
|
| Author: | Steven Watanabe |
|
|
| Review Manager: | Need Volunteer |
|
|
| Download: | [Boost Sandbox Vault](http://boost-consulting.com/vault/index.php?action=downloadfile&filename=mcs_units_v0.7.1.zip&directory=Units) |
|
|
| 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. |

### Property Map (fast-track)
|
|
|
|
|
|
| Author: | Andrew Sutton |
|
|
| Review Manager: | Jeremy Siek |
|
|
| Download: | <http://svn.boost.org/svn/boost/sandbox/graph-v2> |
|
|
| 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) for details.

### Graph
|
|
(fast-track)
|
|
|
|
|
|
| Author: | Andrew Sutton |
|
|
| Review Manager: | Jeremy Siek |
|
|
| Download: | <http://svn.boost.org/svn/boost/sandbox/graph-v2> |
|
|
| 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.

### 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
|
|
|
|
|
|
| Author: | Robert Kawulak |
|
|
| Download: | <http://rk.go.pl/f/constrained_value.zip>
|
|
<http://rk.go.pl/r/constrained_value>
|
|
(Documentation) |
|
|
| 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. |
|
|
|
|
|
|
Please let us know of any libraries you are currently
|
|
developing that you intend to submit for review.
