NAME
File::Find::Object - An object oriented File::Find replacement
SYNOPSIS
use File::Find::Object; my $tree = File::Find::Object->new({}, @targets); while (my $r = $tree->next()) { print $r ."\n"; }
DESCRIPTION
File::Find::Object does the same job as File::Find but works like an object and with an iterator. As File::Find is not object oriented, one cannot perform multiple searches in the same application. The second problem of File::Find is its file processing: after starting its main loop, one cannot easily wait for another event and so get the next result. With File::Find::Object you can get the next file by calling the next() function, but setting a callback is still possible.
FUNCTIONS
new my $ffo = File::Find::Object->new( { options }, @targets); Create a new File::Find::Object object. @targets is the list of directories or files which the object should explore. options depth Boolean - returns the directory content before the directory itself. nocrossfs Boolean - doesn't continue on filesystems different than the parent. followlink Boolean - follow symlinks when they point to a directory. You can safely set this option to true as File::Find::Object does not follow the link if it detects a loop. filter Function reference - should point to a function returning TRUE or FALSE. This function is called with the filename to filter, if the function return FALSE, the file is skipped. callback Function reference - should point to a function, which would be called each time a new file is returned. The function is called with the current filename as an argument. next Returns the next file found by the File::Find::Object. It returns undef once the scan is completed. item Returns the current filename found by the File::Find::Object object, i.e: the last value returned by next(). next_obj Like next() only returns the result as a convenient File::Find::Object::Result object. "$ff->next()" is equivalent to "$ff->next_obj()->path()". item_obj Like item() only returns the result as a convenient File::Find::Object::Result object. "$ff->item()" is equivalent to "$ff->item_obj()->path()". $ff->set_traverse_to([@children]) Sets the children to traverse to from the current node. Useful for pruning items to traverse. $ff->prune() Prunes the current directory. Equivalent to $ff->set_traverse_to([]). [@children] = $ff->get_traverse_to() Retrieves the children that will be traversed to. [@files] = $ff->get_current_node_files_list() Gets all the files that appear in the current directory. This value is constant for every node, and is useful to use as the basis of the argument for "set_traverse_to()".
BUGS
No bugs are known, but it doesn't mean there aren't any.
SEE ALSO
There's an article about this module in the Perl Advent Calendar of 2006: <http://perladvent.pm.org/2006/2/>. File::Find is the core module for traversing files in perl, which has several limitations. File::Next, File::Find::Iterator, File::Walker and the unmaintained File::FTS are alternatives to this module.
