/** |
| 12 |
* Core Pricing Calculation Service |
| 13 |
* |
| 14 |
* Single source of truth for ALL pricing calculations. |
| 15 |
* Both booking session and checkout MUST go through this service. |
| 16 |
* |
| 17 |
* PRICING LOGIC: |
| 18 |
* - Regular pricing: discounted_price → sale_price → original_price |
| 19 |
* - Traveler-based pricing: per-category discounted → sale → original prices |
| 20 |
* |
| 21 |
* FREE PLUGIN FEATURES (handled here): |
| 22 |
* - Base pricing (regular & traveler-based) |
| 23 |
* - Tax calculations (single & multiple) |
| 24 |
* - Coupon discount (via DiscountService) |
| 25 |
* - Group discount (via DiscountService, requires Pro AdvancedDiscount module) |
| 26 |
* - Payment amounts (full only, deposit/partial via Pro) |
| 27 |
* |
| 28 |
* PRO MODULE INTEGRATION (via filter hooks): |
| 29 |
* - Dynamic Pricing → yatra_booking_trip_price (modifies per-unit price) |
| 30 |
* - Additional Services → yatra_booking_services_total (adds services cost) |
| 31 |
* - Advanced Discount → yatra_advanced_discount_enabled (enables group discounts) |
| 32 |
* - Flexible Payments → yatra_calculate_amount_due (deposit/partial payments) |
| 33 |
* |
| 34 |
* FILTER HOOKS (in execution order): |
| 35 |
* 1. yatra_before_calculation_params - Modify input params |
| 36 |
* 2. yatra_booking_trip_price - Dynamic pricing per-unit price modification |
| 37 |
* 3. yatra_calculate_base_amount - Modify calculated base amount |
| 38 |
* 4. yatra_booking_services_total - Additional services cost (Pro) |
| 39 |
* 5. yatra_calculate_subtotal - Modify subtotal (base + services) |
| 40 |
* 6. yatra_calculate_group_discount - Group discount (Pro AdvancedDiscount) |
| 41 |
* 7. yatra_calculate_coupon_discount - Coupon discount |
| 42 |
* 8. yatra_calculate_final_total - Modify final total after tax |
| 43 |
* 9. yatra_calculate_amount_due - Flexible payment amounts (Pro) |
| 44 |
* 10. yatra_after_calculation_result - Modify complete result |
