public function LibraryDependencyResolverInterface::getMinimalRepresentativeSubset

public LibraryDependencyResolverInterface::getMinimalRepresentativeSubset(array $libraries)

Gets the minimal representative subset of the given libraries.

A minimal representative subset means that any library in the given set of libraries that is a dependency of another library in the set, is removed.

Hence a minimal representative subset is the most compact representation possible of a set of libraries.

(Each asset library has dependencies and can therefore be seen as a tree. Hence the given list of libraries represent a forest. This function returns all roots of trees that are not a subtree of another tree in the forest.)

Parameters

string[] $libraries: A set of libraries.

Return value

string[] A representative subset of the given set of libraries.
