Moose::Meta::Attribute::Native::Trait::Number - Helper trait for Num attributes VERSION
version 2.1202 SYNOPSIS
package Real; use Moose; has 'integer' => ( traits => ['Number'], is => 'ro', isa => 'Num', default => 5, handles => { set => 'set', add => 'add', sub => 'sub', mul => 'mul', div => 'div', mod => 'mod', abs => 'abs', }, ); my $real = Real->new(); $real->add(5); # same as $real->integer($real->integer + 5); $real->sub(2); # same as $real->integer($real->integer - 2); DESCRIPTION
This trait provides native delegation methods for numbers. All of the operations correspond to arithmetic operations like addition or multiplication. DEFAULT TYPE
If you don't provide an "isa" value for your attribute, it will default to "Num". PROVIDED METHODS
All of these methods modify the attribute's value in place. All methods return the new value. o add($value) Adds the current value of the attribute to $value. o sub($value) Subtracts $value from the current value of the attribute. o mul($value) Multiplies the current value of the attribute by $value. o div($value) Divides the current value of the attribute by $value. o mod($value) Returns the current value of the attribute modulo $value. o abs Sets the current value of the attribute to its absolute value.

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 2.1202 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
