DESCRIPTION

This is a library of methods for Sub::HandlesVia.

DELEGATABLE METHODS

abs()

Finds the absolute value of the current number, updating the attribute.

  my $object = My::Class->new( attr => -5 );
  $object->my_abs;
  say $object->attr; ## ==> 5

add( $addend )

Arguments: Num.

Adds a number to the existing number, updating the attribute.

  my $object = My::Class->new( attr => 4 );
  $object->my_add( 5 );
  say $object->attr; ## ==> 9

cmp( $num )

Arguments: Num.

Returns "$object->attr <=> $num".

div( $divisor )

Arguments: Num.

Divides the existing number by a number, updating the attribute.

  my $object = My::Class->new( attr => 6 );
  $object->my_div( 2 );
  say $object->attr; ## ==> 3

eq( $num )

Arguments: Num.

Returns "$object->attr == $num".

ge( $num )

Arguments: Num.

Returns "$object->attr >= $num".

get()

Returns the current value of the number.

  my $object = My::Class->new( attr => 4 );
  say $object->my_get; ## ==> 4

gt( $num )

Arguments: Num.

Returns "$object->attr > $num".

le( $num )

Arguments: Num.

Returns "$object->attr <= $num".

lt( $num )

Arguments: Num.

Returns "$object->attr < $num".

mod( $divisor )

Arguments: Num.

Finds the current number modulo a divisor, updating the attribute.

  my $object = My::Class->new( attr => 5 );
  $object->my_mod( 2 );
  say $object->attr; ## ==> 1

mul( $factor )

Arguments: Num.

Multiplies the existing number by a number, updating the attribute.

  my $object = My::Class->new( attr => 2 );
  $object->my_mul( 5 );
  say $object->attr; ## ==> 10

ne( $num )

Arguments: Num.

Returns "$object->attr != $num".

set( $value )

Arguments: Num.

Sets the number to a new value.

  my $object = My::Class->new( attr => 4 );
  $object->my_set( 5 );
  say $object->attr; ## ==> 5

sub( $subtrahend )

Arguments: Num.

Subtracts a number from the existing number, updating the attribute.

  my $object = My::Class->new( attr => 9 );
  $object->my_sub( 6 );
  say $object->attr; ## ==> 3
