All Implemented Interfaces:

Consumer<Object>, Spliterator<T>

Enclosing class:

PluginsContainer

final class PluginsContainer.PluginsSpliterator<T>
extends Spliterators.AbstractSpliterator<T>
implements Consumer<Object>

A spliterator of plugins of the specified type ordered by the processor hierarchy.

The supplied plugins may have duplicates if the same plugin is added into different processors in the hierarchy.

We supply the parent's plugins after this container's plugins so that there is a hierarchical ordering where this container's plugins come before the parent's plugins. Then PluginsContainer.getPlugin(Class) will select a matching plugin from this container, if it exists, versus one from the parent.
