15 "PPIx::Regexp::Token::Code" is a PPIx::Regexp::Token.
16
17 "PPIx::Regexp::Token::Code" is the parent of
18 PPIx::Regexp::Token::Interpolation.
19
21 This class represents a chunk of Perl code embedded in a regular
22 expression. Specifically, it results from parsing things like
23
24 (?{ code })
25 (??{ code })
26
27 or from the replacement side of an s///e. Technically, interpolations
28 are also code, but they parse differently and therefore end up in a
29 different token.
30
31 This token may not appear inside a regex set (i.e. "(?[ ... ])". If
32 found, it will become a "PPIx::Regexp::Token::Unknown".
33
35 This class provides the following public methods. Methods not
36 documented here are private, and unsupported in the sense that the
37 author reserves the right to change or remove them without notice.
38
39 is_matcher
40 This method returns "undef" because a static analysis can not in
41 general tell whether an interpolated value matches anything.
42
43 ppi
44 This convenience method returns the PPI::Document representing the
45 content. This document should be considered read only.
46
47 Note that if the location of the invocant is available the PPI document
48 will have stuff prefixed to it to make the location of the tokens in
49 the new document consistent with the location. This "stuff" will
50 include at least a "#line" directive, and maybe leading white space.
51
