LibraryDependencyResolver
class LibraryDependencyResolver implements LibraryDependencyResolverInterface (View source)
Resolves the dependencies of asset (CSS/JavaScript) libraries.
Properties
| protected LibraryDiscoveryInterface | $libraryDiscovery | The library discovery service. |
|
| protected array | $librariesDependencies | The libraries dependencies. |
Methods
Constructs a new LibraryDependencyResolver instance.
Gets the given libraries with their dependencies.
Gets the given libraries with its dependencies.
Gets the minimal representative subset of the given libraries.
Details
__construct(LibraryDiscoveryInterface $library_discovery)
Constructs a new LibraryDependencyResolver instance.
string[]
getLibrariesWithDependencies(array $libraries)
Gets the given libraries with their dependencies.
Given ['core/a', 'core/b', 'core/c'], with core/a depending on core/c and core/b on core/d, returns ['core/a', 'core/b', 'core/c', 'core/d'].
protected string[]
doGetDependencies(array $libraries_with_unresolved_dependencies, array $final_libraries = [])
Gets the given libraries with its dependencies.
Helper method for ::getLibrariesWithDependencies().
string[]
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.)
