Detailed Description

template<typename T>
struct rti::flat::flat_type_traits< T >

Given a Sample, an Offset or a Builder, it allows obtaining the other types.

Template Parameters

T	One of the following: A Sample type, such as MyFlatMutable An Offset type, such as MyFlatMutableOffset A Builder type, such as MyFlatMutableBuilder

Given T, this type provides the following typedefs:

• flat_type_traits<T>::offset, T's related offset type (undefined if T itself is an Offset)
• flat_type_traits<T>::builder, T's related builder type (undefined if T itself is a Builder, or the topic-type is not mutable)
• flat_type_traits<T>::flat_type, T's related Sample type (undefined if T itself is a Sample type)
• flat_type_traits<T>::plain_type, T's equivalent definition as a plain (non-FlatData) type.

For example, for T = MyFlatMutable, flat_type_traits is defined as follows:

template <>
 struct flat_type_traits<MyFlatMutable> {
     typedef MyFlatMutablePlainHelper plain_type;
     typedef MyFlatMutableOffset offset;
     typedef MyFlatMutableBuilder builder;
 };

Or if T = MyFlatMutableOffset:

template <>
struct flat_type_traits<MyFlatMutableOffset> {
      typedef MyFlatMutable flat_type;
      typedef MyFlatMutablePlainHelper plain_type;
      typedef MyFlatMutableBuilder builder;
};
