.SH NAME
PPIx::Regexp::Token::Interpolation \- Represent an interpolation in the PPIx::Regexp package.
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 2
\& use PPIx::Regexp::Dumper;
\& PPIx::Regexp::Dumper\->new(\*(Aqqr{$foo}smx\*(Aq)\->print();
.Ve
.SH INHERITANCE
.IX Header "INHERITANCE"
\&\f(CW\*(C`PPIx::Regexp::Token::Interpolation\*(C'\fR is a
PPIx::Regexp::Token::Code.
.PP
\&\f(CW\*(C`PPIx::Regexp::Token::Interpolation\*(C'\fR has no descendants.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This class represents a variable interpolation into a regular
expression. In the "SYNOPSIS" the \f(CW$foo\fR would be represented by an
object of this class.
.SS "Incompatible Change: Parse of '@{[ ... ]}'"
.IX Subsection "Incompatible Change: Parse of '@{[ ... ]}'"
In versions 0.083 and earlier, \f(CW\*(Aq@{[ ... ]}\*(Aq\fR parsed as a member of
this class. In 0.084 and later, it parses as a member of
\&\f(CW\*(C`PPIx::Regexp::Token::Code\*(C'\fR. This more accurately reflects the actual
contents of the token, and enables the recognition of the full range of
postfix dereference operators for versioning purposes, not just those
valid in interpolations.
.SH METHODS
.IX Header "METHODS"
This class provides the following public methods beyond those provided
by its superclass.
.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 a piece of code matches anything.
