Access to the archive

$obj->from($source, %options)

Read definitions from the specified $source, which usually can be a filehandle or filename. The syntax used in the information $source is archiver dependent.

Not all archivers implement from(), so you may want to check with UNIVERSAL::can() beforehand.

» example:

use User::Identity::Archive::Some;
my $a = User::Identity::Archive::Some->new('xyz');
$a->from(\*STDIN) if $a->can('from');

DIAGNOSTICS

Error: cannot load collection module for $type ($class): $@

Either the specified $type does not exist, or that module named $class returns compilation errors. If the type as specified in the warning is not the name of a package, you specified a nickname which was not defined. Maybe you forgot the 'require' the package which defines the nickname. Cast by addCollection()

Error: nvalid collection $name.

The collection with $name does not exist and can not be created. Cast by add()

Error: this $object is not a collection.
