@Immutable

Syntax

@Immutable

Description

Target: class, getter method

Purpose: Marker annotation to indicate a class or result of a getter is to be treated immutable. As a result no Proxy is created around the object.

Once a getter method has been marked, the object itself will be cached non-recursively when using a form proxy. Calling setters on such an object directly invoke the original setter and thus won't be tracked.

also see: ProxyHelper.addIgnoredProxyClass(java.lang.Class) This also reduces the resources needed in the application.

Example

@Immutable
public class SysConfiguration {
    // class body
}

public class DataObject {

    //other code...

    @Immutable
    public Price getPrice() {
        return price;
    }
}
