- 要約
- template for 器具／実施するing singleton classes.
- Description
- Such classes can be instanciated everytimes they are needed. But the 内部の wrapped 反対する will be created one times only. Of course its used 資源s are 言及／関連d one times only too. This template 持つ／拘留する it alive till the last 言及／関連 is gone. その上の all 操作／手術s on this 言及／関連 are threadsafe. Only calls 直接／まっすぐに to the 内部の 反対する (which 修正する its 明言する／公表する) must be made threadsafe by the 反対する itself or from outside.
- ATTENTION!
- To 妨げる the code against race 条件s, its not
許すd to start 操作／手術s inside the ctor
of the 内部の wrapped 反対する - especialy 操作／手術s
which needs a 言及／関連 to the same singleton too.
The only chance to supress such strange 星座s
is a lazy-init 機械装置.
- a) The singleton class can 供給する a special init() method, which must be called as first after 創造.
- b) The singleton class can call a special impl_init() method implicit for every called interface method.
