Property

Page Summary

The @Property annotation facilitates the creation of Objective-C property declarations from annotated Java fields, mirroring Apple's @property functionality.
Default attributes like readwrite, strong (with ARC), and atomic are automatically applied and thus omitted from the annotation.
Strings inherently receive the copy attribute for proper memory management in Objective-C.
Utilizing the value method within the annotation enables developers to specify custom attributes like copy and nonatomic for fine-grained control over the generated property declaration.
Errors are generated during compilation if invalid attributes are included within the annotation, ensuring code correctness.

public abstract @interface Property implements Annotation

Adds property declarations to generated Objective-C for annotated fields. See Apple's @property documentation.

Notes:

Invalid attributes are reported as errors.
readwrite, strong (when using ARC), and atomic attributes are removed since they are defaults.
Strings will include the copy attribute.

Example:

 class Foo {
   @Property("copy, nonatomic") protected String bar;
 }

generates:

 @property (copy, nonatomic) NSString *bar;
