Free uml 2.1 software for linux

Dia is designed to be much like the commercial Windows program Visio. It can be used to draw many different kinds of diagrams.

Dia project currently has special objects to help draw entity relationship diagrams, UML diagrams, network diagrams, flowcharts, and simple circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to EPS or SVG formats and can print diagrams (including ones that span multiple pages).

UML::Sequence is a Perl module to render UML sequence diagrams, often by running the code.

SYNOPSIS

use UML::Sequence;

my $tree = UML::Sequence->new(@methods, @outline, &parse_method);
print $tree->build_xml_sequence(Title);

To use this package, or see how to use it, see genericseq.pl and seq2svg.pl.
This class helps produce UML sequence diagrams. build_xml_sequence returns a string (suitable for printing to a file) which the seq2svg.pl script converts into svg.

To control the appearance of the sequence diagram, pass to the constructor:
1 a reference to an array containing the signatures you want to hear about or a reference to a hash whose keys are the signatures you want 2 a reference to an array containing the lines in the outline of calls 3 a reference to a sub which takes signatures and returns class and method names

To build the array references and supply the code reference consult UML::Sequence::SimpleSeq, UML::Sequence::JavaSeq, or UML::Sequence::PerlSeq. To see one way to call these look in the supplied genericseq script.

UML::State is an object oriented module which draws simple state diagrams.

SYNOPSIS

use UML::State;

my $diagram = UML::State->new(
$node_array,
$start_list,
$accept_list,
$edges
);

# You may change these defaults (doing so may even work):
$UML::State::ROW_SPACING = 75; # all numbers are in pixels
$UML::State::LEFT_MARGIN = 20;
$UML::State::WIDTH = 800;
$UML::State::HEIGHT = 800;

print $diagram->draw();

ABSTRACT

Are you tired of pointing and clicking to make simple diagrams? Do your wrists hurt thinking about making the pretty UML your boss likes so well? Consider using UML::State and UML::Sequence to make your life easier.

UML::State together with drawstate.pl allows you to easily generate state diagrams. You enter them in something like a cross between ASCII art and school room algebra. They come out looking like something from a drawing program like Visio. See drawstate.pl in the distribution for details about the input format and the samples directory for some examples of input and output.

You will probably use this class by running drawstate.pl or drawstatexml.pl which are included in the distribution. But you can use this package directly to gain control over the appearance of your pictures.

The two methods you need are new and draw (see below). If you want, you may change the dimensions by setting the package global variables as shown in the SYNOPSIS. Obviously, no error checking is done, so be careful to use reasonable values (positive numbers are good). All numbers are in pixels (sorry by Beziers in SVG seem to require pixels). I have not tried changing the numbers, so I dont have any idea if doing so makes reasonable changes to the output.

OpenSwarm processes your UML 2.0 model to generate a Python server application.

It provides easily customizable business logic based on Python and PostgreSQL. As required by the MDA standard, OpenSwarm uses UML (version 2.0 stored as XMI 2.1).

UDoc is a tool to visualize some Java classes. UDoc dynamically produces some UML-like diagrams from various sources (Javadoc, Java sources, Java binaries).

The diagrams contain a lot of information, and you can easily navigate from classes to classes.
