クラス: ComponentArray<T>

定義: index.ts:601

Efficient sparse-set data structure for storing component data.

Remarks

ComponentArray uses a sparse-set implementation for O(1) insertion, deletion, and lookup while maintaining dense packing for cache-efficient iteration.

The sparse-set consists of:

• Dense array: Packed component data for iteration
• Sparse array: Maps entity ID to dense array index
• Reverse array: Maps dense array index back to entity ID

This structure allows fast component access by entity ID and fast iteration over all components without gaps.
