Net::CLI::Interact::Role::Iterator - Array-based Iterator
VERSION
version 1.121640
SYNOPSIS
my $count = $iter->count;
$iter->reset;
while ( $iter->has_next ) {
print $iter->next;
}
DESCRIPTION
This module implements an array-based iterator which may be mixed-in to add management of a sequence of elements and processing of that
sequence.
The iterator is inspired by MooseX::Iterator but limited to arrays and adds many other facilities. The following section describes the
methods provided by this class.
USAGE
The slot used for storing iterator elements is named "_sequence" and you should write your consuming class to marshall data into this slot,
perhaps via "BUILD" or "init_arg". For example:
has '+_sequence' => (
isa => 'ArrayRef[Thingy]',
init_arg => 'things',
);
INTERFACE
count
The number of elements currently stored in the iterator. Note that this is of course not the same as the index of the last item in the
iterator (which is 0-based)
first
Returns the first item in the iterator.
last
Returns the last item in the iterator.
item_at( $pos )
Returns the item at the given position in the iterator, or throws an exception if $pos is past the end of the iterator. The position is
0-based.
insert_at( $pos, $iter )
Inserts the contents of the passed iterator starting at (not after) the position given. The passed iterator must also be a consumer of this
role. The position is 0-based.
append( $iter )
Shorthand for "insert_at" when you want to add the contents of the passed iterator after the end of the sequence.
idx( $pos? )
Returns the index (0-based) of the current iterator cursor, or sets the cursor if a position (again, 0-based) is passed.
An exception is thrown if you attempt to read the cursor position before having read any elements from the iterator, or if the iterator is
empty.
next
Returns the next item in the iterator sequence, and advances the cursor. Throws an exception if you have already reached the end of the
sequence.
has_next
Returns true if there are further elements to be read from the iterator.
peek
Returns the next item in the sequence without advancing the position of the cursor. It returns "undef" if you are already at the end of the
sequence.
reset
Resets the cursor so you can iterate through the sequence of elements again.

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
