BSON regular expression data.
def __init__ | ( | self, | |
pattern, | |||
flags = 0 |
|||
) |
BSON regular expression data. This class is useful to store and retrieve regular expressions that are incompatible with Python's regular expression dialect. :Parameters: - `pattern`: string - `flags`: (optional) an integer bitmask, or a string of flag characters like "im" for IGNORECASE and MULTILINE

Convert a Python regular expression into a ``Regex`` instance. Note that in Python 3, a regular expression compiled from a :class:`str` has the ``re.UNICODE`` flag set. If it is undesirable to store this flag in a BSON regular expression, unset it first:: >>> pattern = re.compile('.*') >>> regex = Regex.from_native(pattern) >>> regex.flags ^= re.UNICODE >>> db.collection.insert({'pattern': regex}) :Parameters: - `regex`: A regular expression object from ``re.compile()``. .. warning:: Python regular expressions use a different syntax and different set of flags than MongoDB, which uses `PCRE`_. A regular expression retrieved from the server may not compile in Python, or may match a different set of strings in Python than when used in a MongoDB query. .. _PCRE: http://www.pcre.org/
def try_compile | ( | self | ) |
Compile this :class:`Regex` as a Python regular expression. .. warning:: Python regular expressions use a different syntax and different set of flags than MongoDB, which uses `PCRE`_. A regular expression retrieved from the server may not compile in Python, or may match a different set of strings in Python than when used in a MongoDB query. :meth:`try_compile()` may raise :exc:`re.error`. .. _PCRE: http://www.pcre.org/
