== Objects ==
|
|||
|
|
- liberator.plugins.libly.$U
|
|||
|
|
- liberator.plugins.libly.Request
|

|
|
== Logger ==
|
|||
|
|
getLogger(prefix):
|
|||
|
|
log(msg, level), echo(msg, flg), echoerr(msg)
|
|||
|
|
のメソッドを持つ logger インスタンスを取得します。
|
|||
|
|
ログの書式は prefix + ': ' + yyyy/MM/dd + msg となります。
|
|||
|
|
|
|||
|
|
== Object Utility ==
|
|||
|
|
extend(dst, src):
|
|||
|
|
オブジェクトを拡張します。
|
|||
|
|
A(iterable):
|
|||
|
|
オブジェクトを配列にします。
|
|||
|
|
around(obj, name, func, autoRestore):
|
|||
|
|
obj がもつ name 関数を、func に置き換えます。
|
|||
|
|
func は
|
|||
|
|
function (next, args) {...}
|
|||
|
|
という形で呼ばれます。
|
|||
|
|
next はオリジナルの関数を呼び出すための関数、
|
|||
|
|
args はオリジナルの引数列です。
|
|||
|
|
通常、next には引数を渡す必要はありません。
|
|||
|
|
(任意の引数を渡したい場合は配列で渡します。)
|
|||
|
|
また、autoRestore が真であれば、プラグインの再ロードなどで around が再実行されたときに、関数の置き換え前にオリジナル状態に書き戻します。
|
|||
|
|
(多重に置き換えられなくなるので、auto_source.js などを使ったプラグイン開発で便利です)
|
|||
|
|
返値は以下のオブジェクトです
