27 This module provides a simple string attribute, to which mutating
28 string operations can be applied more easily (no need to make an lvalue
29 attribute metaclass or use temporary variables). Additional methods are
30 provided for completion.
31
33 These methods are implemented in
34 MouseX::NativeTraits::MethodProvider::Str. It is important to note that
35 all those methods do in place modification of the value stored in the
36 attribute.
37
38 inc Increments the value stored in this slot using the magical string
39 autoincrement operator. Note that Perl doesn't provide analogous
40 behavior in "--", so "dec" is not available.
41
42 append($string)
43 Append a string, like ".=".
44
45 prepend($string)
46 Prepend a string.
47
48 replace($pattern, $replacement)
49 Performs a regexp substitution ("s" in perlop). A code references
50 will be accepted for the replacement, causing the regexp to be
51 modified with a single "e". "/smxi" can be applied using the "qr"
52 operator.
53
54 replace($pattern, $replacement)
55 Performs a regexp substitution ("s" in perlop) with the "g" flag.
56 A code references will be accepted for the replacement, causing the
57 regexp to be modified with a single "e". "/smxi" can be applied
58 using the "qr" operator.
59
60 match($pattern)
61 Like "replace" but without the replacement. Provided mostly for
62 completeness.
63
64 chop
65 "chop" in perlfunc
66
67 chomp
68 "chomp" in perlfunc
69
70 clear
71 Sets the string to the empty string (not the value passed to
72 "default").
73
74 length
75 "length" in perlfunc
76
77 substr
78 "substr" in perlfunc. We go to some lengths to match the different
79 functionality based on "substr"'s arity.
