CPAN::Meta::Prereqs - a set of distribution prerequisites by phase and type VERSION
version 2.120921 DESCRIPTION
A CPAN::Meta::Prereqs object represents the prerequisites for a CPAN distribution or one of its optional features. Each set of prereqs is organized by phase and type, as described in CPAN::Meta::Prereqs. METHODS
new my $prereq = CPAN::Meta::Prereqs->new( \%prereq_spec ); This method returns a new set of Prereqs. The input should look like the contents of the "prereqs" field described in CPAN::Meta::Spec, meaning something more or less like this: my $prereq = CPAN::Meta::Prereqs->new({ runtime => { requires => { 'Some::Module' => '1.234', ..., }, ..., }, ..., }); You can also construct an empty set of prereqs with: my $prereqs = CPAN::Meta::Prereqs->new; This empty set of prereqs is useful for accumulating new prereqs before finally dumping the whole set into a structure or string. requirements_for my $requirements = $prereqs->requirements_for( $phase, $type ); This method returns a CPAN::Meta::Requirements object for the given phase/type combination. If no prerequisites are registered for that combination, a new CPAN::Meta::Requirements object will be returned, and it may be added to as needed. If $phase or $type are undefined or otherwise invalid, an exception will be raised. with_merged_prereqs my $new_prereqs = $prereqs->with_merged_prereqs( $other_prereqs ); my $new_prereqs = $prereqs->with_merged_prereqs( @other_prereqs ); This method returns a new CPAN::Meta::Prereqs objects in which all the other prerequisites given are merged into the current set. This is primarily provided for combining a distribution's core prereqs with the prereqs of one of its optional features. The new prereqs object has no ties to the originals, and altering it further will not alter them. as_string_hash This method returns a hashref containing structures suitable for dumping into a distmeta data structure. It is made up of hashes and strings, only; there will be no Prereqs, CPAN::Meta::Requirements, or "version" objects inside it. is_finalized This method returns true if the set of prereqs has been marked "finalized," and cannot be altered. finalize Calling "finalize" on a Prereqs object will close it for further modification. Attempting to make any changes that would actually alter the prereqs will result in an exception being thrown. clone my $cloned_prereqs = $prereqs->clone; This method returns a Prereqs object that is identical to the original object, but can be altered without affecting the original object. Finalization does not survive cloning, meaning that you may clone a finalized set of prereqs and then modify the clone. BUGS
