Function Documentation

def tornado.stack_context._nested

(

managers

)

[private]

Support multiple context managers in a single with-statement.

Copied from the python 2.6 standard library.  It's no longer present
in python 3 because the with statement natively supports multiple
context managers, but that doesn't help if the list of context
managers is not known until runtime.

def tornado.stack_context.wrap

(

fn

)

Returns a callable object that will restore the current StackContext
when executed.

Use this whenever saving a callback to be executed later in a
different execution context (either in a different thread or
asynchronously in the same thread).
