METHODS

new

This initializes a new check object.

It takes one value and thht is a hash ref with the key checks. This is a array of hashes.

If new fails, it will die.

checks hash keys

type

This is the name of the check relative to 'Net::Connection::Match::'.

So 'Net::Connection::Match::PTR' would become 'PTR'.

args

This is a hash or args to pash to the check. These are passed to the new method of the check module.

invert

This is either boolean on if the check should be inverted or not.

    my $mce;
    eval{
        $ncm=Net::Connection::Match->new( $args );
    };

match

Checks if a single Net::Connection object matches the stack.

One object is argument is taken and that is the Net::Connection to check.

The return value is a boolean.

    if ( $ncm->match( $conn ) ){
        print "It matched.\n";
    }

ERROR HANDLING / FLAGS

Error handling is provided by Error::Helper.

2 / notNCobj

Not a Net::Connection object. Either is is not defined or what is being passed is not a Net::Connection object.
