PPIx::Regexp::Lexer(3)	       User Contributed Perl Documentation	   PPIx::Regexp::Lexer(3)

NAME
       PPIx::Regexp::Lexer - Assemble tokenizer output.

SYNOPSIS
	use PPIx::Regexp::Lexer;
	use PPIx::Regexp::Dumper;
	my $lex = PPIx::Regexp::Lexer->new('qr{foo}smx');
	my $dmp = PPIx::Regexp::Dumper->new( $lex );
	$dmp->print();

INHERITANCE
       "PPIx::Regexp::Lexer" is a PPIx::Regexp::Support.

       "PPIx::Regexp::Lexer" has no descendants.

DESCRIPTION
       This class takes the token stream generated by PPIx::Regexp::Tokenizer and generates the
       parse tree.

METHODS
       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.

   new
       This method instantiates the lexer. It takes as its argument either a
       PPIx::Regexp::Tokenizer or the text to be parsed. In the latter case the tokenizer is
       instantiated from the text.

       Any optional name/value pairs after the first argument are passed to the tokenizer, which
       interprets them or not as the case may be.

   errstr
       This method returns the error string from the last attempt to instantiate a
       "PPIx::Regexp::Lexer". If the last attempt succeeded, the error will be "undef".

   failures
	print $lexer->failures(), " parse failures\n";

       This method returns the number of parse failures encountered. A parse failure is either a
       tokenization failure (see PPIx::Regexp::Tokenizer->failures()) or a structural error.

   lex
       This method lexes the tokens in the text, and returns the lexed list of elements.

SUPPORT
       Support is by the author. Please file bug reports at <http://rt.cpan.org>, or in
       electronic mail to the author.
