Method Details

resolve

public Map<ScriptResource,FetchMode> resolve(Map<ResourceId,FetchMode> pairs)

Resolve a collection of pair of resource id and fetch mode, each entry of the map will be processed in the order specified by the iteration of the Map.entrySet(). For a given pair the fetch mode may be null or not. When the fetch mode is null, the default fetch mode of the resource is used. When the fetch mode is not null, this fetch mode may override the resource fetch mode if it implies this particular fetch mode. This algorithm tolerates the absence of resources, for instance if a resource is specified (among the pairs or by a transitive dependency) and does not exist, the resource will be skipped.

Parameters:

pairs - the pairs to resolve

Returns:

the resources sorted
