package Nmap::Scanner::Backend::Results;



This class holds the results from a 
scan.  Results include a host
list (Nmap::Scanner::HostList) instance
and an instance of Nmap::Scanner::NmapRun,
which contains information about the
scan.  There are several methods in this 
class used by the scanner to populate the 
result set; the only three that will be of
interest to most programmers are:

=head2 get_host_list()

Returns an instance of 
Nmap::Scanner::HostList that can 
be iterated through to get the host 
objects found by the search.

Example (Assumes scanner 
instance is named $scanner):

my $results = $scanner->scan();

my $host_list = $results->get_host_list();

while (my $host = $host_list->get_next()) {

    print "Found host named: " . $host->hostname() . "\n";
    .. etc ..


=head2 as_xml()

Returns the results as a well-formed 
XML document.

Example (Assumes scanner instance 
is named $scanner):

my $results = $scanner->scan();

print $results->as_xml();

=head2 nmap_run()

Returns the Nmap::Scanner::NmapRun
instance with information about the
scan itself.

See the examples/ directory in the
distribution for more examples.
