Abstract

CloudConnectDataReader reads data stored in our internal binary CloudConnect data format files. It can also read data from compressed files, console, or dictionary.

	Note
Since 2.9 version of CloudConnect CloudConnectDataWriter writes also a header to output files with the version number. For this reason, CloudConnectDataReader expects that files in CloudConnect binary format contain such a header with the version number. CloudConnectDataReader 2.9 cannot read files written by older versions of CloudConnect nor these older versions can read data written by CloudConnectDataWriter 2.9.
