PPIx::Regexp::Token::Quantifier - Represent an atomic quantifier.


 use PPIx::Regexp::Dumper;
 PPIx::Regexp::Dumper->new( 'qr{\w+}smx' )


PPIx::Regexp::Token::Quantifier is a PPIx::Regexp::Token.

PPIx::Regexp::Token::Quantifier has no descendants.


This class represents an atomic quantifier; that is, one of the characters *, +, or ?.

Note that if they occur inside a variable-length look-behind, '?' implies a minimum Perl version of 5.29.9, and '+' and '*' are regarded as parse errors and reblessed into the unknown token.


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.


 PPIx::Regexp::Token::Quantifier->could_be_quantifier( '*' );

This method returns true if the given string could be a quantifier; that is, if it is '*', '+', or '?'.


Support is by the author. Please file bug reports at https://rt.cpan.org/Public/Dist/Display.html?Name=PPIx-Regexp, https://github.com/trwyant/perl-PPIx-Regexp/issues, or in electronic mail to the author.
