Python strings are immutable objects. This has the advantage, that

people from inventing their own mutable string class derived

errors that would be very hard to track down.
A faster and better solution is to rewrite your program using lists."""

# Warning!
#
# This module is tightly bound to the implementation details of the

# is due, in part, to a lack of appropriate methods in the DOM (there is
# no way to create Entity and Notation nodes via the DOM Level 2
# interface), and for performance. The later is the cause of some fairly
# cryptic code.
#
# Performance hacks:
#
# - .character_data_handler() has an extra case in which continuing
# data is appended to an existing Text node; this can be a
# speedup since pyexpat can break up character data into multiple
# callbacks even though we set the buffer_text attribute on the
# parser. This also gives us the advantage that we don't need a
# separate normalization pass.
#
# - Determining that a node exists is done using an identity comparison
# with None rather than a truth test; this avoids searching for and
# calling any methods on the node object if it exists. (A rather
# nice speedup is achieved this way as well!)

"""Fixer for has_key().
Calls to .has_key() methods are expressed in terms of the 'in'
operator:
d.has_key(k) -> k in d
CAVEATS:
1) While the primary target of this fixer is dict.has_key(), the
fixer will change any has_key() method call, regardless of its
class.
2) Cases like this will not be converted:
m = d.has_key
if m(k):

Only *calls* to has_key() are converted. While it is possible to
convert the above to something like
m = d.__contains__
if m(k):

this is currently not done.

module: aos_logical_device_map
author: Damien Garros (@dgarros)
version_added: "2.3"
short_description: Manage AOS Logical Device Map
description:
- Apstra AOS Logical Device Map module let you manage your Logical Device Map easily. You can create
create and delete Logical Device Map by Name, ID or by using a JSON File. This module
is idempotent and support the I(check) mode. It's using the AOS REST API.

- "aos-pyez >= 0.6.0"
options:
session:
description:
- An existing AOS session as obtained by M(aos_login) module.
required: true
name:
description:
- Name of the Logical Device Map to manage.
Only one of I(name), I(id) or I(content) can be set.
id:
description:
- AOS Id of the Logical Device Map to manage (can't be used to create a new Logical Device Map),
Only one of I(name), I(id) or I(content) can be set.
content:
description:
- Datastructure of the Logical Device Map to manage. The data can be in YAML / JSON or
directly a variable. It's the same datastructure that is returned
on success in I(value). Only one of I(name), I(id) or I(content) can be set.

"""Streaming HTTP uploads module.
This module extends the standard httplib and urllib2 objects so that
iterable objects can be used in the body of HTTP requests.
In most cases all one should have to do is call :func:`register_openers()`
to register the new streaming http handlers which will take priority over
the default handlers, and then you can use iterable objects in the body
of HTTP requests.
**N.B.** You must specify a Content-Length header if using an iterable object
since there is no way to determine in advance the total size that will be
yielded, and there is no way to reset an interator.
Example usage:
>>> from StringIO import StringIO
>>> import urllib2, poster.streaminghttp
>>> opener = poster.streaminghttp.register_openers()
>>> s = "Test file data"
>>> f = StringIO(s)
>>> req = urllib2.Request("http://localhost:5000", f,
... {'Content-Length': str(len(s))})
