NAME
VS::RuleEngine::Rule::InputOverThreshold - Generic rule for checking input thresholds
SYNOPSIS
use VS::RuleEngine::Declare;
my $engine = engine {
rule 'valid_name' => instanceof "VS::RuleEngine::Rule::InputOverThreshold" => with_args {
'input_1' => 5,
'input_2' => -5,
}
}
DESCRIPTION
This is a generic rule that checks if the value from an input is equal or passes 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 | match
>= y | y < 0 | no match
<= y | y < 0 | match
<= y | y > 0 | no 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.
