Defining the streamContents() Function

Next, the streamContents() function is defined for this class by putting macros in the source file for the class.

// real_property.cpp

RW_BEGIN_STREAM_CONTENTS(real_property) // 1

{

RW_STREAM_ATTR_MEMBER(address, address_) // 2

RW_STREAM_ATTR_MEMBER(size, size_)

}

RW_END_STREAM_CONTENTS // 3

//1 This macro begins the definition of the streamContents() function.

//2 This macro defines the code for inserting and extracting data to and from the address_ and size_ data members of the real_property class.

//3 The streamContents() function is closed out with this macro.
