Composite Pattern
Compose objects into tree structures to represent part-whole hierarchies. Let clients treat individual objects and compositions uniformly.
Composite pattern wraps files and folders under a single FileSystemNode interface, allowing clients to invoke actions uniformly.
Core Design Challenge
"How do we compute directory sizes recursively without writing distinct loops for files and folders?"
What You'll Learn:
- ✦Representing tree hierarchies of part-whole relationships
- ✦Executing uniform traversals over groups and leaf nodes
- ✦Treating individual objects and compositions uniformly
- ✦Simplifying recursive logic across nested structures
