NAME

PPIx::QuoteLike::Token::Interpolation - Represent an interpolation

SYNOPSIS

This class should not be instantiated by the user. See below for public methods.

INHERITANCE

PPIx::QuoteLike::Token::Interpolation is a PPIx::QuoteLike::Token.

PPIx::QuoteLike::Token::Interpolation has no descendants.

DESCRIPTION

This Perl class represents an interpolation into a quote-like string.

METHODS

This class supports the following public methods in addition to those of its superclass:

ppi

 my $ppi = $elem->ppi();

This convenience method returns the PPI::Document representing the content. This document should be considered read only. An exception will be thrown if PPI::Document can not be loaded.

Note that the content of the returned PPI::Document may not be the same as the content of the original PPIx::Regexp::Token::Interpolation. This can happen because interpolated variable names may be enclosed in curly brackets, but this does not happen in normal code. For example, in /${foo}bar/, the content of the PPIx::Regexp::Token::Interpolation object will be '${foo}', but the content of the PPI::Document will be '$foo'.

variables

 say "Interpolates $_" for $elem->variables();

This convenience method returns all interpolated variables. Each is returned only once, and they are returned in no particular order.
