Class Name: PriceResultWrapper¶

Last Updated: 2025-10-22 Source Code: PriceResultWrapper.cls

API Name: PriceResultWrapper Type: Model/Wrapper (Data Transfer Object) Test Coverage: Not specified

Business Purpose¶

This lightweight wrapper class facilitates the transfer of product pricing data between Apex controllers and Lightning Web Components or Aura Components. It provides a standardized format for passing product ID, price, and pricebook entry information to member-facing interfaces, supporting AANP's e-commerce and product catalog functionality.

Class Overview¶

Sharing Model: N/A (data transfer object with no logic)
Access Modifier: global
Interfaces Implemented: None

Key Responsibilities¶

Provides simple data structure for product pricing information
Enables Lightning component access with @AuraEnabled properties
Supports serialization for client-server communication
Maintains product ID, price, and pricebook entry relationship in a single object
Facilitates data transfer between server and client layers

Public Methods¶

No methods - this is a pure data container with only properties.

Public Properties¶

productId¶

@AuraEnabled
public Id productId

Purpose: Stores the Product2 record ID for the priced product.

Type: Id

Usage: Links the price information to a specific product in the catalog.

price¶

@AuraEnabled
public Decimal price

Purpose: Stores the calculated or retrieved price for the product.

Type: Decimal

Usage: Contains the actual price value to be displayed to users or used in calculations.

pbEntryId¶

@AuraEnabled
public String pbEntryId

Purpose: Stores the Pricebook Entry ID associated with this pricing result.

Type: String

Usage: Links to the specific pricebook entry that determined this price.

Private/Helper Methods¶

No helper methods - this is a pure data container.

Dependencies¶

Apex Classes¶

None (standalone data structure)

Salesforce Objects¶

Product2: productId references Product2 records
PricebookEntry: pbEntryId references PricebookEntry records

Custom Settings/Metadata¶

None

External Services¶

None (used internally for data transfer)

Design Patterns¶

Data Transfer Object (DTO) Pattern: Pure data container for transferring pricing information
Serializable Object Pattern: @AuraEnabled enables JSON serialization
Value Object Pattern: Represents pricing data without identity

Governor Limits Considerations¶

SOQL Queries: None (data container only) DML Operations: None (data container only) CPU Time: None (no logic) Heap Size: Minimal - 3 properties per instance

Bulkification: N/A (data structure) Async Processing: N/A (data structure)

Note: Multiple instances may be created and passed to Lightning components - consider memory usage with large product lists.

Error Handling¶

Strategy: No error handling (data container) Logging: None User Notifications: None

Note: Consuming code should validate property values before use.

Security Considerations¶

Sharing Rules: N/A (no query or DML logic) Field-Level Security: Not enforced (consumer responsibility) CRUD Permissions: Not checked (consumer responsibility) Input Validation: None - properties accept any valid values

Security Notes: - Global access modifier allows usage across all namespaces - No validation of property values - consumers must validate - Price information is sensitive - ensure secure transmission to client - Consumers should verify user has permission to view pricing data

Test Class¶

Test Class: Not specified Coverage: Not applicable (no logic to test) Test Scenarios: - Typically tested indirectly through consuming classes - Verify serialization to Lightning components works correctly - Test null value handling in consuming code - Verify correct data mapping from source to wrapper

Changes & History¶

Added pbEntryId property (date unknown) - not in original documentation

Pre-Go-Live Concerns¶

CRITICAL - Fix Before Go-Live¶

NO VALIDATION: Class lacks any validation for productId, price, or pbEntryId values
NULL HANDLING: No protection against null values
NEGATIVE PRICE HANDLING: No validation to prevent negative or invalid prices
NO CONSTRUCTORS: Consider adding constructors for easier object initialization

HIGH - Address Soon After Go-Live¶

Add constructor methods: Provide constructors for easier instantiation and validation
Implement validation: Add validation for price ranges and ID formats
Consider currency support: Add currency or locale information for international pricing
Add null checks: Validate that required properties are populated

MEDIUM - Future Enhancement¶

Add additional pricing fields: List price, discount amount, discount percentage, etc.
Implement comparison methods: Enable sorting and filtering of price results
Add toString() method: Improve debugging and logging capabilities
Add metadata fields: Currency code, effective date, expiration date, etc.
Implement equals/hashCode: Enable proper comparison and collection usage

LOW - Monitor¶

Usage patterns: Monitor how different Lightning components use this wrapper
Performance impact: Track memory usage in high-volume scenarios
Property usage: Determine if all properties are actually used
Serialization size: Monitor JSON payload size for client communication

Maintenance Notes¶

Complexity: Very Low Recommended Review Schedule: Annually or when pricing requirements change

Key Maintainer Notes: - This is a simple data transfer object - keep it simple and focused - Do not add business logic to this class - it should remain a pure data container - Any validation should be added through constructor methods, not property setters - Consider immutability if the class becomes more complex - The global access modifier means any code in any namespace can use this - Changes to property names will break Lightning components - coordinate carefully

Critical Dependencies: - Lightning Web Component framework for serialization - Product2 and PricebookEntry objects for ID references - Consuming controllers and components for proper usage

Usage Guidelines: - Use for transferring pricing data from Apex to Lightning components - Instantiate and populate properties in controller methods - Return as single object or List for multiple prices - Validate data before populating wrapper properties - Consider null checks in JavaScript consuming code

Common Pitfalls: - Properties are public and mutable - consumers can modify values - No validation means invalid data can be passed through - pbEntryId is String type but should contain a valid ID - Global access could lead to unexpected usage across packages - Changing property names breaks existing Lightning components

Recommended Enhancements: 1. Add parameterized constructor for easier instantiation 2. Add validation in constructor for required fields 3. Consider making properties final (immutable) with constructor assignment 4. Add builder pattern if complexity increases 5. Add documentation comments on each property 6. Consider adding @JsonProperty annotations if using external JSON libraries
