Sub::Rate::NoMaxRate - auto calculate max_rate
my $rate = Sub::Rate::NoMaxRate->new; $rate->add( 10 => sub { ... } ); # sub1 $rate->add( 20 => sub { ... } ); # sub2 my $func = $rate->generate; # Calling this $func then: # sub1 will be called by rate about 10/30 # sub2 will be called by rate about 20/30 $func->();
Sub::Rate::NoMaxRate is a subclass of Sub::Rate.
This module has no max_rate
option and calculate it automatically.
my $obj = Sub::Rate->new;
Create Sub::Rate object.
Available options are:
Random calculate function. Default is:
sub { CORE::rand($_[0]); };
You can change random function to your own implementation by this option. max_rate
is passed as $_[0]
to this function.
$obj->add( 10, sub { ... } ); $obj->add( 20, sub { ... } ); $obj->add( 'default', sub { ... } );
Add $sub
to internal sublist rate by $rate
.
If $rate
is not number but "default", then $sub
is registered as default sub. If default sub is already registered, it will be replaced.
my $sub = $obj->generate;
Create a new sub that dispatch functions by its rates.
$obj->clear;
Clear all registered functions and default function.
