#forget_dependencies_for(object) ⇒ void

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

This method returns an undefined value.

Empties the list of dependencies for the given object. This is necessary before recompiling the given object, because otherwise old dependencies will stick around and new dependencies will appear twice. This function removes all incoming edges for the given vertex.

Parameters:

#objects_causing_outdatedness_of(object) ⇒ Array<Nanoc::Core::Item, Nanoc::Core::Layout, nil>

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns the direct dependencies for the given object.

The direct dependencies of the given object include the items and layouts that, when outdated will cause the given object to be marked as outdated. Indirect dependencies will not be returned (e.g. if A depends on B which depends on C, then the direct dependencies of A do not include C).

The direct predecessors can include nil, which indicates an item that is no longer present in the site.

#record_dependency(src, dst, raw_content: false, attributes: false, compiled_content: false, path: false) ⇒ void

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

This method returns an undefined value.

Records a dependency from ‘src` to `dst` in the dependency graph. When `dst` is oudated, `src` will also become outdated.
