Used to generate get/set pairs for - * field members automatically. Valid options are: 'name', 'readOnly', - * 'writeOnly', 'useGet', 'preCallMethod', and 'preCallThrows'. - *

- *'name' may be used to set an alternative name for the property instead of - * defaulting to the field's name. - *

- *'readOnly' and 'writeOnly' may be set to true to create only a getter or a - * setter, respectively. - *

- *'useGet' is used to generate a getX instead of isX method if the property is - * a boolean. - *

- *'preCallMethod' is the name of the method to be invoked prior to setting the - * actual property value. It may be used for validation, or firing off - * PropertyChangeEvents. This method will be called as - * preCallMethod(this, String propertyName, oldValue, newValue); - * since this occurs at compile time, there is no interface, so the types are - * entirely up to you to choose and make work. The method may also be any - * method, so long as it's accessible to the bean. Thus, - * preCallMethod=anotherObject.validateProperty would be ok, so - * long as anotherObject is a field within the bean. The object - * navigation leading up to the preCallMethod cannot contain any method - * invocations; e.g. - * preCallMethod=someBean.someMethod().myPreCallMethod would be - * illegal and cause an error. - *

- *'preCallThrows' specifies what exceptions can possibly be thrown by the - * preCallMethod. Any non-RuntimeExceptions must be specified here, or - * else it will result in a compile-time error. This information cannot be - * determined reflectively, because at compile-time, there is no reflection - * (reflection is for runtime use).
