Constructor Details

#initialize(specification = nil) ⇒ Connection

With no argument, uses the connection specified in the configuration file, or defaults to Redis on localhost, port 6379. If the argument is a string, it is processed as a URL. If the argument is a Hash, and contains a key `:redis` the value is used as a redis connection. Otherwise, the argument is a hash and specifies the adapter name and any additional options understood by that adapter (as with config/vanity.yml). Note that all keys are expected to be symbols.

Examples:

Vanity::Connection.new
Vanity::Connection.new("redis://redis.local/5")
$shared_redis_connection = Redis.new
Vanity::Connection.new(adapter: :redis, redis: $shared_redis_connection)
Vanity::Connection.new(
  :adapter=>:redis,
  :host=>"redis.local"
)
