Enforce type on queries

If:

• Entity_ would be a a generic type like Entity_<Entity>
• each property would also be a generic type like Property<Entity>
• the QueryBuilder#equal method (and others) would take Property<Entity> as arguments

then the IDE would warn in case of the following statement:

boxForA.query().equal(propertyForB, 42L).build()

(mixing a property of entity B against the box for A)

What do you think?

首先，检查提案中提到的 Entity_、Property 和 QueryBuilder#equal 类型，以及周围的查询 API。确定 IDE 是否可以在不破坏现有用法的情况下拒绝实体与属性之间的不匹配；当预期的类型约束及其兼容性影响得到定义和验证后，该 issue 即完成。
