NAME
ProgressMonitor::Null - a monitor implementation which doesn't render anything. Useful if a receiver insists on a monitor impl to talk to.
SYNOPSIS
...
$someObj->someLongRunningMethod(ProgressMonitor::Null->new);
...
####
useful pattern inside a method that takes a monitor instance
but can accept undef for it:
someMethod
{
my $monitor = shift;
monitor = ProgressMonitor::Null->new unless $monitor;
...
#now the rest of the code is guaranteed a monitor
...
}
DESCRIPTION
This is a 'null' implementation of the ProgressMonitor interface. It will simply ignore to render anything, thus it's a good dropin for a method that requires a monitor instance but you don't wish anything shown.
Inherits from AbstractStatefulMonitor.
