NAME

VS::RuleEngine::Rule::InputUnderThreshold - Generic rule for checking input thresholds

SYNOPSIS

            

              
              
use VS::RuleEngine::Declare;
my $engine = engine {
    rule 'valid_name' => instanceof "VS::RuleEngine::Rule::InputUnderThreshold" => with_args {
        'input_1' => 5,
        'input_2' => -5,
    }
}
            
          

DESCRIPTION

This is a generic rule that checks if the value from an input is does not pass a threshold relative to 0. This can be used to model change matrices where a row represets a rule.

The following table shows the conditions when it matches

            

              
              
Input | Threshold | Result
------+-----------+-------
x     | 0         | match
> y   | y > 0     | no match
> y   | y < 0     | match 
< y   | y < 0     | no match
< y   | y > 0     | match
            
          

USAGE

Rule arguments

This rule expects a hash reference as its argument, which is what with_args provides, where the key is the name of an input and the value is the expected threshold value.
