Definition
Getter Methods in Apex are methods that return the value of a class property or variable. They use the get accessor keyword and are commonly used in Visualforce controllers to make data available to Visualforce pages for display. For example, a getter method like public String getName() { return 'Hello'; } allows a Visualforce page to reference {!name} and display the returned value. Getter methods work alongside setter methods to control read and write access to controller properties.
Real-World Example
At their company, a developer at Quantum Labs leverages Getter Methods to build a custom solution that extends the platform beyond its standard capabilities. They write clean, bulkified code for Getter Methods, add comprehensive test coverage, and deploy it through a CI/CD pipeline. The new functionality handles 10,000 records without hitting governor limits.
Why Getter Methods Matters
Getter Methods in Apex are methods that return the value of a class property or variable. They use the get accessor convention (or are explicitly defined methods like getName()) and are commonly used in Visualforce controllers to make data available to Visualforce pages for display. For example, a getter method like public String getName() { return 'Hello'; } in a controller lets a Visualforce page reference {!name} and display the returned value.
Getter methods work alongside setter methods to control read and write access to controller properties. The pattern was central to Visualforce development, which used the JavaBeans-style getter/setter convention for binding controllers to pages. Modern Lightning Web Components have a different architecture (component properties with @api decorators) that doesn't use the same getter/setter pattern, though developers writing more complex LWCs still use JavaScript getters for computed properties. For new development, LWC is the recommended path; for maintaining legacy Visualforce code, understanding getter methods remains essential.
How Organizations Use Getter Methods
- •TerraForm Tech — Maintains legacy Visualforce code where getter methods bind controller data to page elements through {!name} syntax.
- •CodeBridge — Trains developers on getter/setter patterns for legacy Visualforce work, while emphasizing that new development should use LWC's different patterns.
- •Quantum Labs — Uses JavaScript getters in LWC for computed properties, applying the same general concept to a different framework.
