我想知道,在 Java(通过Javadoc或默示公约)是否有任何公约表明,在几个情况下,某个相同的类别可以重复使用?
I am asking that because in the SWT layout context I don t know if I am allowed to reuse the same GridLayout object for several Composite objects. I guess the answer is Yes after checking the source code (I can t see any state fields) but the Javadoc doesn t explicitly state it. Maybe the implicit convention is that "sharing" is allowed if not explicitly forbidden ?
默示公约是否允许“分享”,如果没有明确禁止的话?
没有这样的公约。
相反,你应当采取审慎的做法,即,只有 Java明你能够安全地这样做时,你才应当重新使用。
阅读《守则》和观察与目前执行《守则》是安全的,这并不能保证在未来释放或提前释放中分享。 只依靠有文件记载的行为是个好主意。
