LocalStack
[source]¶ This class works similar to a
Local
but keeps a stack of objects instead. This is best explained with an example:>>> ls = LocalStack() >>> ls.push(42) >>> ls.top 42 >>> ls.push(23) >>> ls.top 23 >>> ls.pop() 23 >>> ls.top 42
They can be force released by using a
LocalManager
or with therelease_local()
function but the correct way is to pop the item from the stack after using. When the stack is empty it will no longer be bound to the current context (and as such released).By calling the stack without arguments it returns a proxy that resolves to the topmost item on the stack.
