Constant Summary collapse
- FMT_MASK =
Bitmask for flag bits responsible for format
0x03
- FMT_DOCUMENT =
Document format. The (default) format supports most of ruby types which could be mapped to JSON data (hashes, arrays, strings, numbers). Future version will be able to run map/reduce queries on the values in the document form (hashes).
0x00
- FMT_MARSHAL =
Marshal format. The format which supports transparent serialization of ruby objects with standard
Marshal.dump
andMarhal.load
methods. 0x01
- FMT_PLAIN =
Plain format. The format which force client don’t apply any conversions to the value, but it should be passed as String. It could be useful for building custom algorithms or formats. For example implement set: dustin.github.com/2011/02/17/memcached-set.html

#default_format ⇒ Symbol
Amending default_format will also change #default_flags value
Default format for new values.
It uses flags field to store the format. It accepts either the Symbol (:document
, :marshal
, :plain
) or Fixnum (use constants FMT_DOCUMENT, FMT_MARSHAL, FMT_PLAIN) and silently ignores all other value.
Here is some notes regarding how to choose the format:
-
:document
(default) format supports most of ruby types which could be mapped to JSON data (hashes, arrays, strings, numbers). Future version will be able to run map/reduce queries on the values in the document form (hashes). -
:plain
format if you no need any conversions to be applied to your data, but your data should be passed as String. It could be useful for building custom algorithms or formats. For example implement set: dustin.github.com/2011/02/17/memcached-set.html -
:marshal
format if you’d like to transparently serialize your ruby object with standardMarshal.dump
andMarhal.load
methods.

#transcoder ⇒ Object
Set data transcoder for the current connection
It is possible to define custom transcoder to handle all value transformation, for example, if you need to adopt legacy application. The transcoder should respond to two methods: dump
and load
. They are accepting the data itself, the flags field, and the options hash from the library.
@example Simple data transcoder, which use Zlib to compress documents
class ZlibTranscoder
FMT_ZLIB = 0x04
def initialize(base)
@base = base
end
def dump(obj, flags, options = {})
obj, flags = @base.dump(obj, flags, options)
z = Zlib::Deflate.new(Zlib::BEST_SPEED)
buffer = z.deflate(obj, Zlib::FINISH)
z.close
[buffer, flags|FMT_ZLIB]
end
def load(blob, flags, options = {})
# decompress value only if Zlib flag set
if (flags & FMT_ZLIB) == FMT_ZLIB
z = Zlib::Inflate.new
blob = z.inflate(blob)
z.finish
z.close
end
@base.load(blob, flags, options)
end

#append(key, value, options = {}) ⇒ Fixnum
This operation is kind of data-aware from server point of view. This mean that the server treats value as binary stream and just perform concatenation, therefore it won’t work with :marshal
and :document
formats, because of lack of knowledge how to merge values in these formats. See #cas for workaround.

#async? ⇒ true, false
Check whether the connection asynchronous.
By default all operations are synchronous and block waiting for results, but you can make them asynchronous and run event loop explicitly. (see #run)

#cas(key, options = {}) {|value| ... } ⇒ Fixnum Also known as: compare_and_swap
Compare and swap value.
Reads a key’s value from the server and yields it to a block. Replaces the key’s value with the result of the block as long as the key hasn’t been updated in the meantime, otherwise raises Error::KeyExists. CAS stands for “compare and swap”, and avoids the need for manual key mutexing. Read more info here:
In asynchronous mode it will yield result twice, first for #get with Result#operation equal to :get
and second time for #set with Result#operation equal to :set
.

#decr(key, delta = 1, options = {}) {|ret| ... } ⇒ Fixnum Also known as: decrement
that server values stored and transmitted as unsigned numbers, therefore if you try to decrement negative or zero key, you will always get zero.
Decrement the value of an existing numeric key
The decrement methods reduce the value of a given key if the corresponding value can be parsed to an integer value. These operations are provided at a protocol level to eliminate the need to get, update, and reset a simple integer value in the database. It supports the use of an explicit offset value that will be used to reduce the stored value in the database.

#incr(key, delta = 1, options = {}) {|ret| ... } ⇒ Fixnum Also known as: increment
that server values stored and transmitted as unsigned numbers, therefore if you try to store negative number and then increment or decrement it will cause overflow. (see “Integer overflow” example below)
Increment the value of an existing numeric key
The increment methods allow you to increase a given stored integer value. These are the incremental equivalent of the decrement operations and work on the same basis; updating the value of a key if it can be parsed to an integer. The update operation occurs on the server and is provided at the protocol level. This simplifies what would otherwise be a two-stage get and set operation.

contains the name of the statistical item and the #value
contains the value, the #node
will indicate the server address). In synchronous mode it returns the hash of stats keys and node-value pairs as a value.

Update the expiry time of an item
The touch
method allow you to update the expiration time on a given key. This can be useful for situations where you want to prevent an item from expiring without resetting the associated value. For example, for a session database you might want to keep the session alive in the database each time the user accesses a web page without explicitly updating the session value, keeping the user’s session active and available.
