Question

I was wondering if it could be possible to create a databinding system in pure actionscript without using mx.binding.utils. At least I would like to know what is the overhead of the databinding code and how exactly the ChangeWatcher knows when a property has been changed. Thank you!

There s a lot of work that goes on behind the scenes when you bind data, but he gives a really good explanation of how it works. It s a bit awkward to create something that works automatically unless you re passing through a "compile" phase where you add code.

Answer 2

比较法的汇编者实际上将自己的数据和元数据交换法/AS3汇编成纯粹的AS3,然后将其汇编成全线编码。因此,在汇编过程的某个阶段,数据约束力实际上正在以行动文本执行。

问题是,“灵活”为数据约束专门增加了一bit。没有什么东西阻止你在SAP3中建立数据约束性制度,但有一些限制,例如,你必须以AS3的方式这样做。
