Description
This class represents a chunk of Perl code embedded in a regular expression. Specifically, it results
from parsing things like
(?{ code })
(??{ code })
or from the replacement side of an s///e. Technically, interpolations are also code, but they parse
differently and therefore end up in a different token.
This token may not appear inside a regex set (i.e. "(?[ ... ])". If found, it will become a
"PPIx::Regexp::Token::Unknown".
Inheritance
"PPIx::Regexp::Token::Code" is a PPIx::Regexp::Token.
"PPIx::Regexp::Token::Code" is the parent of PPIx::Regexp::Token::Interpolation.
Methods
This class provides the following public methods. Methods not documented here are private, and
unsupported in the sense that the author reserves the right to change or remove them without notice.
is_matcher
This method returns "undef" because a static analysis can not in general tell whether an interpolated
value matches anything.
ppi
This convenience method returns the PPI::Document representing the content. This document should be
considered read only.
Note that if the location of the invocant is available the PPI document will have stuff prefixed to it to
make the location of the tokens in the new document consistent with the location. This "stuff" will
include at least a "#line" directive, and maybe leading white space.
