A Unicode character class.
Whether this class is negated or not.
Note: be careful when using this attribute. This specifically refers
to whether the class is written as \p
or \P
, where the latter
is negated = true
. However, it also possible to write something like
\P{scx!=Katakana}
which is actually equivalent to
\p{scx=Katakana}
and is therefore not actually negated even though
negated = true
here. To test whether this class is truly negated
or not, use the is_negated
method.
The kind of Unicode class.
Returns true if this class has been negated.
Note that this takes the Unicode op into account, if it's present.
e.g., is_negated
for \P{scx!=Katakana}
will return false
.
