Detailed Description

Class handling the definition of the format for serialization of data streams.

The adsk::Data::Stream class manages stream definitions. They are persisted using a serialization format implemented through the adsk::Data::StreamSerializer hierarchy. The base class defines the interface and manages the list of available stream serialization formats.

#include <adskDataStreamSerializer.h>

Implement this to parse the serialized form of an adsk::Data::Stream object.

Given an input stream containing your serialization of an adsk::Data::Stream object parse the data and create the adsk::Data::Stream object it describes.

If there are any problems the detailed error information should be returned in the errors string.

The adsk::Data::Stream parsing should also recursively populate any data within the adsk::Data::Stream. This method should be capable of understanding any data which your adsk::Data::StreamSerializer::write method can provide.

Parameters:

[in]	cSrc	Input stream containing serialization of the adsk::Data::Stream
[out]	errors	String containing description of parse errors

Returns:

Pointer to the newly created adsk::Data::Stream object

int write	(	const Stream &	dataToWrite,
		std::ostream &	cDst,
		std::string &	errors
	)		const [pure virtual]

Implement this to output the adsk::Data::Stream definition in your serialization format.

Given an adsk::Data::Stream object and an output stream as destination write out enough information so that you can recreate the adsk::Data::Stream from data in the output stream using your adsk::Data::StreamSerializer::read() method.

This serialization should include all data values within the adsk::Data::Stream obejct.

Parameters:

[in]	dataToWrite	adsk::Data::Stream to be serialized
[out]	cDst	stream to which the object is to be serialized
[out]	errors	String containing description of write errors

Returns:

number of errors found during write (0 means success)

Implement this to provide a description of your adsk::Data::Stream serialization format.

Output a textual description of your serialization format into the given stream.

Parameters:

[out]

stream in which to output your serialization format description
