Multiple @ImportStatic annotations on a single class using the Java Preon library

Question

I'm wondering if there is a way to use multiple @ImportStatic annotations for a single class with Preon?

I tried:

@ImportStatic(classA.class)
@ImportStatic(classB.class)

// Also tried:

@ImportStatic(classA.class classB.class)

// And: 
@ImportStatic(classA.class,classB.class)

None of these are valid however...

I have a specification that asks me to look at the enum value (classA) of the outer (parent) class, if it matches a specific value, then I must also do an enum check on on one of the parents other object's enum values (classB) before proceeding to read the next field.

EDIT: Here's my first attempt at a solution, basically copy ImportStatic and make an ImportStatic2 annotation... Have to see how well it works.

使用以下语法可以正常工作：

@ImportStatic({First.class,Second.class})
