PPIx::Regexp::Token::Code \- Represent a chunk of Perl embedded in a regular expression.

.PP
\&\f(CW\*(C`PPIx::Regexp::Token::Code\*(C'\fR is the parent of
PPIx::Regexp::Token::Interpolation.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class represents a chunk of Perl code embedded in a regular
expression. Specifically, it results from parsing things like
.PP
.Vb 2
\& (?{ code })
\& (??{ code })
.Ve
.PP
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.
.PP
This token may not appear inside a regex set (i.e. \f(CW\*(C`(?[ ... ])\*(C'\fR. If
found, it will become a \f(CW\*(C`PPIx::Regexp::Token::Unknown\*(C'\fR.
.SH "METHODS"
.IX Header "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.
.SS "is_matcher"
.IX Subsection "is_matcher"
This method returns \f(CW\*(C`undef\*(C'\fR because a static analysis can not in
general tell whether an interpolated value matches anything.
.SS "ppi"
.IX Subsection "ppi"
This convenience method returns the PPI::Document
representing the content. This document should be considered read only.
.PP
\&\fBNote\fR that if the location of the invocant is available the \s-1PPI\s0
document will have stuff prefixed to it to make the location of the
tokens in the new document consistent with the location. This \*(L"stuff\*(R"
will include at least a \f(CW\*(C`#line\*(C'\fR directive, and maybe leading white
space.
