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
";

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