Algorithm::Dependency::Item - Implements an item in a dependency hierarchy.
The Algorithm::Dependency::Item class implements a single item within the dependency hierarchy. It's quite simple, usually created from within a source, and not typically created directly. This is provided for those implementing their own source. ( See Algorithm::Dependency::Source for details ).
new constructor takes as its first argument the id ( name ) of the item, and any further arguments are assumed to be the ids of other items that this one depends on.
Returns a new
Algorithm::Dependency::Item on success, or
undef on error.
id method returns the id of the item.
depends method returns, as a list, the names of the other items that this item depends on.
