NAME

DBIx::Locker::Lock - a live resource lock

VERSION

version 0.100113

METHODS

new

Calling this method is a very, very stupid idea. This method is called by DBIx::Locker to create locks. Since you are not a locker, you should not call this method. Seriously.

my $locker = DBIx::Locker::Lock->new(\%arg);

This returns a new lock.

locker    - the locker creating the lock
lock_id   - the id of the lock in the lock table
expires   - the time (in epoch seconds) at which the lock will expire
locked_by - a hashref of identifying information

locker

lock_id

locked_by

These are accessors for data supplied to "new".

expires

This method returns the expiration time (as a unix timestamp) as provided to "new" -- unless expiration has been changed. Expiration can be changed by using this method as a mutator:

# expire one hour from now, no matter what initial expiration was
$lock->expired(time + 3600);

When updating the expiration time, if the given expiration time is not a valid unix time, or if the expiration cannot be updated, an exception will be raised.

guid

This method returns the lock's globally unique id.

unlock

This method unlocks the lock, deleting the semaphor record. This method is automatically called when locks are garbage collected.
