JGraph Layout Pro 1.4.0.4 (Default branch)
02-25-2008
JGraph Layout Pro is a high performance graph layout library for JGraph that automatically positions your graph, diagram, or network in a visually pleasing manner. Layout Pro provides flexibility and a simple design, enabling you to use circular, tree, force-directed, and hierarchical layouts with ease. Example uses are organisational charts, workflow and process diagrams, call charts, network diagrams, UML tools, and more. It comes with its own documentation and an example applet.

Graph::Easy::Layout::Path(3pm) User Contributed Perl Documentation Graph::Easy::Layout::Path(3pm) NAME
Graph::Easy::Layout::Path - Path management for Manhattan-style grids SYNOPSIS
use Graph::Easy; my $graph = Graph::Easy->new(); my $bonn = Graph::Easy::Node->new( name => 'Bonn', ); my $berlin = Graph::Easy::Node->new( name => 'Berlin', ); $graph->add_edge ($bonn, $berlin); $graph->layout(); print $graph->as_ascii( ); # prints: # +------+ +--------+ # | Bonn | --> | Berlin | # +------+ +--------+ DESCRIPTION
"Graph::Easy::Layout::Scout" contains just the actual path-managing code for Graph::Easy, e.g. to create/destroy/maintain paths, node placement etc. EXPORT
Exports nothing. SEE ALSO
Graph::Easy. METHODS into Graph::Easy This module injects the following methods into "Graph::Easy": _path_is_clear() $graph->_path_is_clear($path); For all points (x,y pairs) in the path, check that the cell is still free. $path points to a list x,y,type pairs as in "[ [x,y,type], [x,y,type], ...]". _create_cell() my $cell = $graph->($edge,$x,$y,$type); Create a cell at "$x,$y" coordinates with type $type for the specified edge. _path_is_clear() $graph->_path_is_clear(); For all points (x,y pairs) in the path, check that the cell is still free. $path points to a list of "[ x,y,type, x,y,type, ...]". Returns true when the path is clear, false otherwise. _trace_path() my $path = my $graph->_trace_path($src,$dst,$edge); Find a free way from source node/group to destination node/group for the specified edge. Both source and destination need to be placed beforehand. METHODS in Graph::Easy::Node This module injects the following methods into "Graph::Easy::Node": _near_places() my $node->_near_places(); Take a node and return a list of possible placements around it and prune out already occupied cells. $d is the distance from the node border and defaults to two (for placements). Set it to one for adjacent cells. _shuffle_dir() my $dirs = $node->_shuffle_dir( [ 0,1,2,3 ], $dir); Take a ref to an array with four entries and shuffle them around according to $dir. _shift() my $dir = $node->_shift($degrees); Return a the "flow()" direction shifted by X degrees to $dir.
