Blob

The Blob class extends the Stream class and provides a flexible way to manage binary data located in the system memory. The class also includes functions for base64 encoding and decoding, as well as calculating message digests using MD5 and SHA1 hash algorithms.

#include <core/TellusimBlob.h>

Inheritance​

Constructors​

explicit Blob(const char *name = nullptr)

Blob(const Blob &blob, bool move)

Methods​
