NAME
Parse::CPAN::MirroredBy - Parse MIRRORED.BY
DESCRIPTION
Like the other members of the Parse::CPAN family Parse::CPAN::MirroredBy
parses and processes the CPAN meta data file MIRRORED.BY.
METHODS
new
Creates a new, simple, parser object.
add_map
# Instead of the full hash just read the hostname
$parser->add_map( sub { $_[0]->{hostname} } );
The "add_map" method adds a map stage to the filter pipeline.
A single element is passed into the provided function from the previous
pipeline phase, and one or more values can be returned which will be
passed on to the next pipeline phase.
Returns true if added, or throws an exception if a non-CODE reference is
provided.
add_grep
# We only want the daily mirrors
$parser->add_grep( sub { $_[0]->{frequency} eq 'daily' } );
The "add_grep" method adds a grep phase to the filter pipeline.
A single value is passed into the provided function, and the function
should return true if the value is to be kept, or false if not.
Returns true if added, or throws an exception if a non-CODE reference is
provided.
add_bless
# Bless into whatever objects
$parser->add_bless( 'Foo::Whatever' );
For situations in which you wish to convert the pipeline values into
objects directly, and don't want to do it via a map phase that passes
values into a contructor, the "add_bless" method allows you to provide a
class name that the elements of the pipe will be passed to.
parse_file
my @mirrors = $parser->parse_file( 'MIRRORED.BY' );
Once the parser is ready to process the file, the "parse_file" method
can be provided a file name to read. It will read the file, passing the
contents through the filter pipeline, and returning the resulting values
as a list of results.
parse
my @mirrors = $parser->parse( $file_handle );
Once the parser is ready to process the file, the "parse" method can be
provided a file handle to read. It will read from the file handle,
passing the contents through the filter pipeline, and returning the
resulting values as a list of results.
