Discovers information for asset (CSS/JavaScript) libraries. Library information is statically cached. Libraries are keyed by extension for several reasons: Libraries are not unique. Multiple extensions might ship with the same library in a different version or variant. This registry cannot (and does not attempt to) prevent library conflicts. Extensions implementing and thereby depending on a library that is registered by another extension can only rely on that extension's library. Two (or more)

public LibraryDiscoveryCollector::__construct(CacheBackendInterface $cache, LockBackendInterface $lock, LibraryDiscoveryParser $discovery_parser, ThemeManagerInterface $theme_manager) Constructs a CacheCollector object. Parameters \Drupal\Core\Cache\CacheBackendInterface $cache: The cache backend. \Drupal\Core\Lock\LockBackendInterface $lock: The lock backend. \Drupal\Core\Asset\LibraryDiscoveryParser $discovery_parser: The library discovery parser. \Drupal\Core\Theme\ThemeManagerInterface $th

protected LibraryDiscoveryCollector::resolveCacheMiss($key) Resolves a cache miss. When an offset is not found in the object, this is treated as a cache miss. This method allows classes using this implementation to look up the actual value and allow it to be cached. Parameters string $key: The offset that was requested. Return value mixed The value of the offset, or NULL if no value was found. Overrides CacheCollector::resolveCacheMiss File core/lib/Drupal/Core/Asset/LibraryDiscoveryCollector

public LibraryDiscoveryCollector::reset() Resets the local cache. Does not clear the persistent cache.

protected LibraryDiscoveryCollector::getLibraryDefinitions($extension) Returns the library definitions for a given extension. This also implements libraries-overrides for entire libraries that have been specified by the LibraryDiscoveryParser. Parameters string $extension: The name of the extension for which library definitions will be returned. Return value array The library definitions for $extension with overrides applied.
