EGG::RamStream Class Reference

#include <Stream.hh>

Description

A stream of data stored in memory.

RamStream solves two problems:

1. Inconsistent endianness across Kinoko clients.
2. Having to maintain pointer arithmetic while reading in various data types. We specify the endianness of the data in the stream, and the stream will handle the rest.

Definition at line 127 of file Stream.cc.

split()

RamStream EGG::RamStream::split ( u32 size )

nodiscard

Splits the current stream into two.

Segments the current stream at the current index. The returned stream is the data from the current index to size bytes after. The current stream is then moved to size bytes after the current index.
