NAME¶
TM::ResourceAble::MemCached - Topic Maps, Memcached server backend
SYNOPSIS¶
use TM::ResourceAble::MemCached;
use Fcntl;
# create/reset new map
my $tm = new TM::ResourceAble::MemCached (
baseuri => 'http://whereever/',
servers => [ localhost:11211 ],
mode => O_TRUNC | O_CREAT,
);
# use TM interface
# open existing map
my $tm = new TM::ResourceAble::MemCached (
baseuri => 'http://whereever/',
servers => [ localhost:11211 ],
);
DESCRIPTION¶
This package implements TM using a memcached server farm as backend. You should
be able (without much testing, mind you, so it is EXPERIMENTAL) to perform all
operations according to the TM interface.
NOTE: The implementation is using the TIE technique (perltie via
Tie::StdHash), so maybe there are problems lurking.
Of course, a set of memcacheds can store any number of maps. To keep them
separate, the baseuri is used, so make sure every map gets its own baseuri.
INTERFACE¶
Constructor¶
The constructor expects a hash with the following keys:
- servers (default: none)
- The value must be a reference to an array of strings, each of the form
host: port. If there is no such list, then the constructor
will fail.
- mode (default: O_CREAT)
- The value must be a value from Fcntl to control
- •
- whether the map should be created ("O_CREAT") when it does not
exist, and/or
- •
- whether the map should be cleared ("O_TRUNC") when it existed
before.
All other options are passed to the constructor chain of traits
(TM::ResourceAble) and superclasses (TM).
