Framework Primitives Builders Collections and Tree Utilities

Builders, Collections & Tree Utilities

Use this area when the question is construction ergonomics, observable collections, or tree traversal.

Three Groups

• immutable fluent builders and additive create helpers
• observable collections and paging primitives
• traversal helpers such as walk, find, and expanded-tree walks

Practical Rules

• builders are immutable and reusable
• required fields validate at build time
• collection batching and VM container batching are separate scopes
• tree utilities are pure reads
