smpl.plot.ExitStack

class smpl.plot.ExitStack

Bases: _BaseExitStack, AbstractContextManager

Context manager for dynamic management of a stack of exit callbacks.

For example:

with ExitStack() as stack:

files = [stack.enter_context(open(fname)) for fname in filenames] # All opened files will automatically be closed at the end of # the with statement, even if attempts to open files later # in the list raise an exception.

__init__()

Methods

__init__()
callback(callback, /, *args, **kwds)	Registers an arbitrary callback and arguments.
close()	Immediately unwind the context stack.
enter_context(cm)	Enters the supplied context manager.
pop_all()	Preserve the context stack by transferring it to a new instance.
push(exit)	Registers a callback with the standard __exit__ method signature.

callback(callback, /, *args, **kwds)

Registers an arbitrary callback and arguments.

Cannot suppress exceptions.

close()

Immediately unwind the context stack.

enter_context(cm)

Enters the supplied context manager.

If successful, also pushes its __exit__ method as a callback and returns the result of the __enter__ method.

pop_all()

Preserve the context stack by transferring it to a new instance.

push(exit)

Registers a callback with the standard __exit__ method signature.

Can suppress exceptions the same way __exit__ method can. Also accepts any object with an __exit__ method (registering a call to the method instead of the object itself).
