What is the use of getter strategies and setter techniques in Visualforce Pages in Salesforce?

Hi Hariom,

Getter Methods-
Getter methods return values from a controller. Every value that is calculated by a controller and displayed in a page must have a corresponding getter method, including any Boolean variables. For example, in the sample page in Building a Custom Controller, the controller includes a getAccount method. This method allows the page markup to reference theaccount member variable in the controller class with {! } notation. The value parameter of the <apex:inputField> tag uses this notation to access the account, and dot notation to display the account's name. Getter methods must always be named getVariable.

Setter Methods
Setter methods pass user-specified values from page markup to a controller. Any setter methods in a controller are automatically executed before any action methods.

Thanks.

Hi Hariom

Setter method : This will take the value from the visualforce page and stores to the Apex variable name.
getter method : This method will return a value to a visualforce page whenever a name variable is called.

Visualforce is a markup language that allows you to describe the user interface components that live on your Force.com .Visualforce is the component-based user interface framework for the Force.com platform. The framework includes a tag-based markup language; similar to HTML.Visualforce is used for building various attractive and dynamic applications.Visualforce lives on the server. So any code you write will be generated and run on the server.
