I have a calendar which i toggle between the view of Day Week and month using ViewStack
I want to delete the previous view objects or unused memory when i am in an other view
all the views are custom components, which are loading several child objects at a time.
when i navigate frm day to month view the objects of the child view are still persisted.
I used removechild() method, but its not actually deleting the obj, but keeoing its reference.
which method is used to delete the unsused objs explicitally.

Flash has a "garbage collection" facility that deletes objects, at some indeterminate point, provided they are no longer referenced by any active variables or event listeners. Actionscript doesn't let you directly remove anything from memory. It just gives you the opportunity to make objects eligible for garbage collection. For this reason, it's a good idea to make event listeners weak (set the 5th argument in addEventListener to true) and/or to use removeEventListener when/if they become unnecessary.

To make an object eligible for garbage collection, the best you can do is to set to null any class-level variables (properties) on it or referencing it, and to use the delete operator(?) with each dynamically declared property of it, if, like the Object class, it supports dynamically declared properties.
