VERSION
Version 3.26
SYNOPSIS
use TAP::Parser::Multiplexer;
my $mux = TAP::Parser::Multiplexer->new;
$mux->add( $parser1, $stash1 );
$mux->add( $parser2, $stash2 );
while ( my ( $parser, $stash, $result ) = $mux->next ) {
# do stuff
}
DESCRIPTION
"TAP::Parser::Multiplexer" gathers input from multiple TAP::Parsers.
Internally it calls select on the input file handles for those parsers
to wait for one or more of them to have input available.
See the TAP::Harness manpage for an example of its use.
METHODS
Class Methods
"new"
my $mux = TAP::Parser::Multiplexer->new;
Returns a new "TAP::Parser::Multiplexer" object.
Instance Methods
"add"
$mux->add( $parser, $stash );
Add a TAP::Parser to the multiplexer. "$stash" is an optional opaque
reference that will be returned from "next" along with the parser and
the next result.
"parsers"
my $count = $mux->parsers;
Returns the number of parsers. Parsers are removed from the multiplexer
when their input is exhausted.
"next"
Return a result from the next available parser. Returns a list contain‐
ing the parser from which the result came, the stash that corresponds
with that parser and the result.
my ( $parser, $stash, $result ) = $mux->next;
If "$result" is undefined the corresponding parser has reached the end
of its input (and will automatically be removed from the multiplexer).
When all parsers are exhausted an empty list will be returned.
if ( my ( $parser, $stash, $result ) = $mux->next ) {
if ( ! defined $result ) {
# End of this parser
}
else {
# Process result
}
}
else {
# All parsers finished
}
