fun filterKeys(predicate: (AttributeKey<*>) -> Boolean): AttributeContainer

Returns a new AttributeContainer containing only the attributes whose keys match the predicate.

Link copied to clipboard
operator fun <T> get(key: AttributeKey<T>): T?

Retrieves the attribute value for the specified key. If not set, it returns null.
