Constructors

  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

  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.

Instance Methods

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 "!".
