/**

* 标记不可变对象。根据约定,该对象的字段只能是不可变对象或基础数据类型,且都是只读的。如:
|
||||
* <pre>@ImmutableObject
|
||||
* class Foo {
|
||||
* private final @Getter int intVal;
|
||||
* private final @Getter String stringVal;
|
||||
* private final @Getter LocalDate dateVal;
|
||||
* private final @Getter BigDecimal decimalVal;
|
||||
* }
|
||||
* </pre>
|
||||
* <p>
|
||||
* 如 guava 的 ImmutableList、ImmutableMap 等不可变集合,不属于此,因为其不要求包含的元素本身是不可变的。
