Detailed Description

Wraps a StreamDataSequence and provides convenient access functions.

The binary data in the stream is assumed to be in little-endian format.

Constructor & Destructor Documentation

◆ SequenceInputStream()

oox::SequenceInputStream::SequenceInputStream ( const StreamDataSequence & rData )

explicit

Constructs the wrapper object for the passed data sequence.

Attention: \n: The passed data sequence MUST live at least as long as this stream wrapper. The data sequence MUST NOT be changed from outside as long as this stream wrapper is used to read from it.
