Hello,
Please tell me if there is a better way to get the number of elements from an array that is passed to a function.
This is what works on Solaris 8 (ksh) but it looks odd:

array_name=$2

b2='}'
nr_elements=`eval echo... (6 Replies)

moose::meta::attribute::native::trait::counter
Moose::Meta::Attribute::Native::Trait::Counter(3) User Contributed Perl Documentation Moose::Meta::Attribute::Native::Trait::Counter(3) NAME
Moose::Meta::Attribute::Native::Trait::Counter - Helper trait for Int attributes which represent counters VERSION
version 2.0604 SYNOPSIS
package MyHomePage; use Moose; has 'counter' => ( traits => ['Counter'], is => 'ro', isa => 'Num', default => 0, handles => { inc_counter => 'inc', dec_counter => 'dec', reset_counter => 'reset', }, ); my $page = MyHomePage->new(); $page->inc_counter; # same as $page->counter( $page->counter + 1 ); $page->dec_counter; # same as $page->counter( $page->counter - 1 ); my $count_by_twos = 2; $page->inc_counter($count_by_twos); DESCRIPTION
This trait provides native delegation methods for counters. A counter can be any sort of number (integer or not). The delegation methods allow you to increment, decrement, or reset the value. DEFAULT TYPE
If you don't provide an "isa" value for your attribute, it will default to "Num". PROVIDED METHODS
o set($value) Sets the counter to the specified value and returns the new value. This method requires a single argument. o inc o inc($arg) Increases the attribute value by the amount of the argument, or by 1 if no argument is given. This method returns the new value. This method accepts a single argument. o dec o dec($arg) Decreases the attribute value by the amount of the argument, or by 1 if no argument is given. This method returns the new value. This method accepts a single argument. o reset Resets the value stored in this slot to its default value, and returns the new value. BUGS
