    private function init(array $items, string $itemFqcn)

This method is not used, and could be removed.

    {
        $this->itemFqcn = $itemFqcn;
        foreach ($items as $key => $item) {
            $this->assertItemKey($key);

    }

    private function assertItemKey($key)

This method seems to be duplicated in your project.

    {
        if (!is_string($key)) {
            throw new \Exception(sprintf(
                'Invalid item-key given to %s. Expected string but was given %s',
                static::CLASS,
                is_object($key) ? get_class($key) : @gettype($key)
            ));
        }
    }

    private function assertItemType($item)

This method seems to be duplicated in your project.

    {
        if (!is_a($item, $this->itemFqcn)) {
            throw new \Exception(sprintf(
                'Invalid item-type given to %s. Expected %s but was given %s',
                static::CLASS,
                $this->itemFqcn,
                is_object($item) ? get_class($item) : @gettype($item)
            ));
        }
    }

    public function __clone()
    {
        $this->compositeMap = new Map($this->compositeMap->toArray());
    }
