NAME

6       PPIx::QuoteLike::Token::Interpolation - Represent an interpolation
7

SYNOPSIS

9       This class should not be instantiated by the user. See below for public
10       methods.
11

INHERITANCE

13       "PPIx::QuoteLike::Token::Interpolation" is a PPIx::QuoteLike::Token.
14
15       "PPIx::QuoteLike::Token::Interpolation" has no descendants.
16

DESCRIPTION

18       This Perl class represents an interpolation into a quote-like string.
19

METHODS

21       This class supports the following public methods in addition to those
22       of its superclass:
23
24   ppi
25        my $ppi = $elem->ppi();
26
27       This convenience method returns the PPI::Document representing the
28       content. This document should be considered read only.  An exception
29       will be thrown if PPI::Document can not be loaded.
30
31       Note that the content of the returned PPI::Document may not be the same
32       as the content of the original "PPIx::Regexp::Token::Interpolation".
33       This can happen because interpolated variable names may be enclosed in
34       curly brackets, but this does not happen in normal code. For example,
35       in "/${foo}bar/", the content of the
36       "PPIx::Regexp::Token::Interpolation" object will be '${foo}', but the
37       content of the "PPI::Document" will be '$foo'.
38
39   variables
40        say "Interpolates $_" for $elem->variables();
41
42       NOTE that this method is discouraged, and may well be deprecated and
43       removed. I have two problems with it. The first is that it returns
44       variable names rather than PPI::Element objects, leaving you no idea
45       how the variables are used. The second is that it does not properly
46       handle things like "${^CAPTURE[0]}", and it seems infeasible to make it
47       do so. It was originally written for the benefit of
48       Perl::Critic::Policy::Variables::ProhibitUnusedVarsStricter, but has
49       proven inadequate to that policy's needs.
50
51       This convenience method returns all interpolated variables. Each is
52       returned only once, and they are returned in no particular order.
