Graph::BitMatrix Description

Graph::BitMatrix is Perl module to create and manipulate a V x V bit matrix of graph G. Graph::BitMatrix is Perl module to create and manipulate a V x V bit matrix of graph G.SYNOPSIS use Graph::BitMatrix; use Graph::Directed; my $g = Graph::Directed->new; $g->add_...(); # build $g my $m = Graph::BitMatrix->new($g, %opt); $m->get($u, $v) $m->set($u, $v) $m->unset($u, $v) $m->get_row($u, $v1, $v2, ..., $vn) $m->set_row($u, $v1, $v2, ..., $vn) $m->unset_row($u, $v1, $v2, ..., $vn) $a->vertices()This class enables creating bit matrices that compactly describe the connected of the graphs.Class Methodsnew($g) Create a bit matrix from a Graph $g. The %opt, if present, can have the following options:connect_edges If true or if not present, set the bits in the bit matrix that correspond to edges. If false, do not set any bits. In either case the bit matrix of V x V bits is allocated.Object Methodsget($u, $v) Return true if the bit matrix has a "one bit" between the vertices $u and $v; in other words, if there is (at least one) a vertex going from $u to $v. If there is no vertex and therefore a "zero bit", return false.set($u, $v) Set the bit between the vertices $u and $v; in other words, connect the vertices $u and $v by an edge. The change does not get mirrored back to the original graph. Returns nothing.unset($u, $v) Unset the bit between the vertices $u and $v; in other words, disconnect the vertices $u and $v by an edge. The change does not get mirrored back to the original graph. Returns nothing.get_row($u, $v1, $v2, ..., $vn) Test the row at vertex u for the vertices v1, v2, ..., vn Returns a list of n truth values.set_row($u, $v1, $v2, ..., $vn) Sets the row at vertex u for the vertices v1, v2, ..., vn, in other words, connects the vertex u to the vertices vi. The changes do not get mirrored back to the original graph. Returns nothing.unset_row($u, $v1, $v2, ..., $vn) Unsets the row at vertex u for the vertices v1, v2, ..., vn, in other words, disconnects the vertex u from the vertices vi. The changes do not get mirrored back to the original graph. Returns nothing.vertices Return the list of vertices in the bit matrix. Requirements: · Perl
