Hello again, I feel like I'm posting quite often lately...
I am just finishing up a major site and am trying to make sure it is optimized properly. I have been reading a lot of posts on resource management, including articles by gskinner and senocular about the garbage collector and everything, so I have an idea of what I need to do, but I just want to clarify a few things:
1. Removing an object from the display list and setting it to null will mark it for collection? Or does every reference to that object also need to be removed. And is using 'object=null' the best way?
2. When an object gets collected does this remove all its children as well, or does each child need to be removed individually?
3. Do you need to remove all stored data in an instance (ie. arrays and objects storing reference variables, external data, etc). Or will this be removed with an instance?
4. I read that reusing objects is a good way to conserve memory, so does replacing one instance of a class with another actually remove the original one? For example:
object = new classInstance1();
object = new classInstance2();
Does this mean classInstance1 no longer exists, or is ready for collection?
Right now I'm just setting cleanUp() functions within display classes that get called before an instance is removed, removing and nulling all children, removing any remaining event listeners, etc. but I haven't seen any examples of resource management in actual use, so is this a valid way to do it?
Sorry if these are stupid questions, I'm just trying to wrap my head around this whole process. Thanks in advance!
