/**
|
|
* @brief Implement the conversion of object data to data streams
|
|
* or vice-versa, using linked lists.
|
|
* @details
|
|
* An alternative to the AutoSerializeAdapter functions
|
|
* - All object members with a datatype are declared as
|
|
* SerializeElement<element_type> members inside the class
|
|
* implementing this adapter.
|
|
* - The element type can also be a SerialBufferAdapter to
|
|
* de-/serialize buffers with a known size
|
|
* - The element type can also be a SerialFixedArrayListAdapter to
|
|
* de-/serialize buffers with a size header, which is scanned automatically.
|
|
*
|
|
* The sequence of objects is defined in the constructor by using
|
|
* the setStart and setNext functions.
|
|
*
|
|
* 1. The serialization process is done by instantiating the class and
|
|
* calling serialize after all SerializeElement entries have been set by
|
|
* using the constructor or setter functions. An additional size variable
|
|
* can be supplied which is calculated/incremented automatically.
|
|
* 2. The deserialization process is done by instantiating the class and
|
|
* supplying a buffer with the data which is converted into an object.
|
|
* The size of data to serialize can be supplied and is
|
|
* decremented in the function. Range checking is done internally.
