ExternalizeVerifier (Groovy 2.5.11)

```
@Documented
@Retention(SOURCE)
@Target(TYPE)
public @interface ExternalizeVerifier
```
Class annotation used to assist in the creation of Externalizable classes. The @ExternalizeVerifier annotation instructs the compiler to check that a class has writeExternal() and readExternal() methods, implements the Externalizable interface and that each property (and optionally field) is not final and, optionally for non-primitives, has a type which is either Externalizable or Serializable. Properties or fields marked as transient are ignored. This annotation is typically used in conjunction with the @ExternalizeMethods annotation but most usually not directly but rather via @AutoExternalizable which is a shortcut for both annotations.

Optional Element Summary

  - excludes
```
String[] excludes
```
    Comma separated list of property names to exclude from externalization verification. For convenience, a String with comma separated names can be used in addition to an array (using Groovy's literal list notation) of String values.
    
    Default:
    
    {}
- - includeFields
```
boolean includeFields
```
    Include fields as well as properties when verifying externalization properties.
    
    Default:
    
    false
- - checkPropertyTypes
```
boolean checkPropertyTypes
```
    Turns on strict type checking for property (or field) types. In strict mode, such types must also implement Serializable or Externalizable. If your properties have interface types that don't implement Serializable but all the concrete implementations do, or the type is of a non-Serializable class but the property will be null at runtime, then your instances will still be serializable but you can't turn on strict checking.
    
    Default:
    
    false
