This module provides a simple string attribute, to which mutating string
operations can be applied more easily (no need to make an lvalue attribute
metaclass or use temporary variables). Additional methods are provided for
completion.
These methods are implemented in MouseX::NativeTraits::MethodProvider::Str. It
is important to note that all those methods do in place modification of the
value stored in the attribute.
- inc
- Increments the value stored in this slot using the magical string
autoincrement operator. Note that Perl doesn't provide analogous behavior
in "--", so
"dec" is not available.
- append($string)
- Append a string, like ".=".
- prepend($string)
- Prepend a string.
- replace($pattern, $replacement)
- Performs a regexp substitution ("s" in perlop). A code
references will be accepted for the replacement, causing the regexp to be
modified with a single "e".
"/smxi" can be applied using the
"qr" operator.
- replace($pattern, $replacement)
- Performs a regexp substitution ("s" in perlop) with the
"g" flag. A code references will be
accepted for the replacement, causing the regexp to be modified with a
single "e".
"/smxi" can be applied using the
"qr" operator.
- match($pattern)
- Like "replace" but without the
replacement. Provided mostly for completeness.
- chop
- "chop" in perlfunc
- chomp
- "chomp" in perlfunc
- clear
- Sets the string to the empty string (not the value passed to
"default").
- length
- "length" in perlfunc
- substr
- "substr" in perlfunc. We go to some lengths to match the
different functionality based on
"substr"'s arity.
- meta
- method_provider_class
- helper_type
