App::Sqitch::Plan::Depend - Sqitch dependency specification

       David E. Wheeler <david@justatheory.com>

       An App::Sqitch::Plan::Line represents a single dependency from the dependency list for a planned change.
       Is is constructed by App::Sqitch::Plan and included in App::Sqitch::Plan::Change objects "conflicts" and
       "requires" attributes.

Constructors"new"

         my $depend = App::Sqitch::Plan::Depend->new(%params);

       Instantiates and returns a App::Sqitch::Plan::Line object. Parameters:

       "plan"
           The plan with which the dependency is associated. Required.

       "project"
           Name of the project. Required.

       "conflicts"
           Boolean to indicate whether the dependency is a conflicting dependency.

       "change"
           The name of the change.

       "tag"
           The name of the tag claimed as the dependency.

       "id"
           The ID of a change. Mutually exclusive with "change" and "tag".

       "parse"

         my %params = App::Sqitch::Plan::Depend->parse($string);

       Parses  a  dependency  specification  as extracted from a plan and returns a hash reference of parameters
       suitable for passing to new(). Returns "undef" if the string is not a properly-formatted dependency.

   Accessors"plan"

         my $plan = $depend->plan;

       Returns the App::Sqitch::Plan object with which the dependency specification is associated.

       "conflicts"

         say $depend->as_string, ' conflicts' if $depend->conflicts;

       Returns true if the dependency is a conflicting dependency, and false if it is not (in which case it is a
       required dependency).

       "required"

         say $depend->as_string, ' required' if $depend->required;

       Returns true if the dependency is a required, and false if it is not (in which case it is  a  conflicting
       dependency).

       "type"

         say $depend->type;

       Returns a string indicating the type of dependency, either "require" or "conflict".

       "project"

         my $proj = $depend->project;

       Returns the name of the project with which the dependency is associated.

       "got_project"

       Returns  true if the "project" parameter was passed to the constructor with a defined value, and false if
       it was not passed to the constructor.

       "change"

         my $change = $depend->change;

       Returns the name of the change, if any. If "undef" is returned, the dependency is a tag-only dependency.

       "tag"

         my $tag = $depend->tag;

       Returns the name of the tag, if any. If "undef" is returned, the dependency is a change-only dependency.

       "id"

       Returns the ID of the change if the dependency was specified as an ID, or if the dependency  is  a  local
       dependency.

       "got_id"

       Returns  true  if  the "id" parameter was passed to the constructor with a defined value, and false if it
       was not passed to the constructor.

       "resolved_id"

       Change ID used by the engine when deploying a change. That is, if the dependency is in the  database,  it
       will be assigned this ID from the database.  If it is not in the database, "resolved_id" will be undef.

       "is_external"

       Returns  true  if  the dependency references a change external to the current project, and false if it is
       part of the current project.

       "is_internal"

       The opposite of is_external(): returns true if the dependency is in the internal (current)  project,  and
       false if not.

   InstanceMethods"key_name"

       Returns  the  key name of the dependency, with the change name and/or tag, properly formatted for passing
       to the find() method of App::Sqitch::Plan. If the dependency was specified as an ID, rather than a change
       or tag, then the ID will be returned.

       "as_string"

       Returns the project-qualified key name. That is, if there is a project name, it returns a string with the
       project name, a colon, and the key name. If there is no project name, the key name is returned.

       "as_plan_string"

         my $string = $depend->as_string;

       Returns the full stringification of the dependency, suitable for output to a plan file. That is, the same
       as "as_string" unless "conflicts" returns true, in which case it is prepended with "!".
