NAME
Hydrogen::Counter - a standard library for integer counters
VERSION
This documentation is for Hydrogen::Counter 0.020000, which is based on Sub::HandlesVia::HandlerLibrary::Counter 0.046.
FUNCTIONS
Each function expects an integer as its first argument.
dec( $counter, $amount? )
Additional arguments: Optional[Int].
Decrements the counter by $amount, or by 1 if no value is given.
inc( $counter, $amount? )
Additional arguments: Optional[Int].
Increments the counter by $amount, or by 1 if no value is given.
reset( $counter )
Sets the counter to its default value, or 0 if it has no default.
set( $counter, $value )
Additional arguments: Int.
Sets the counter to the given value.
EXPORT
No functions are exported by this module by default. To import them all (this is usually a bad idea), use:
use Hydrogen::Counter -all;To import a particular function, use:
use Hydrogen::Counter 'reset';To rename functions:
use Hydrogen::Counter 'reset' => { -as => 'myfunc' };On Perl 5.37.2+ (or if Lexical::Sub is installed) you can import lexically:
use Hydrogen::Counter -lexical, 'reset';See Exporter::Tiny::Manual::Importing for more hints on importing.
