An array of translated categories, sorted alphabetically.

in CategorizingPluginManagerInterface at line 28
array[] getSortedDefinitions(array $definitions = NULL)

Gets sorted plugin definitions.

Parameters

array $definitions

(optional) The plugin definitions to sort. If omitted, all plugin definitions are used.

PluginDefinitionInterface[]|array[] getFilteredDefinitions(string $consumer, ContextInterface[]|null $contexts = NULL, array $extra = [])

Gets the plugin definitions for a given type and consumer and filters them.

This allows modules and themes to alter plugin definitions at runtime, which is useful for tasks like hiding specific plugins from a particular user interface.

Parameters
