Method Details

find

public abstract <T>
Collection<ExtensionComponent<T>> find(Class<T> type)

Discover extensions of the given type.

This method is called only once per the given type after all the plugins are loaded, so implementations need not worry about caching.

Type Parameters:

Returns:

Can be empty but never null.

union

public static ExtensionComponentSet union(Collection<? extends ExtensionComponentSet> base)

Computes the union of all the given delta.
