Design mistakes lead to confusion between a "leaf" and a "container". --- ### 2. **Difficulty Restricting the Tree's Composition** Composite treats all elements as "equal": a client can add anything anywhere. This makes it hard to **forbid logically invalid operations**: for example, inserting a file into another file. --- ### 3. **A Growing Number of Small Objects** In large structures, a huge number of small objects (nodes, collections, wrappers) are created, which increases the load on memory and garbage collection. --- ### 4. **Performance Problems During Recursion** If the tree is deep, frequent recursive traversals (for example, computing size or searching) can be **expensive** and require optimization. --- ### 5. **Difficulty Debugging and Tracing** Because of polymorphism and recursion, it is hard to tell exactly where an error occurred: in a leaf, in a container, or during traversal. --- **Summary:** Composite makes working with hierarchies flexible and transparent, but at the cost of **increased structural complexity, recursion, and weak control over the tree's contents**.For the reviewerNote to the moderator (optional)Visible only to the moderator.
