## Detailed Description

A memory buffer.

Implements sharing semantics using reference counting.

## Constructor & Destructor Documentation

ipe::Buffer::Buffer | ( |  | ) |
| defaultnoexcept

Referenced by ipe::Lex::skipWhitespace().

Buffer::~Buffer | ( |  | ) |
| noexcept

Destructor.

Buffer::Buffer | ( | const Buffer & | rhs | ) |
| noexcept

Copy constructor. Constant time, buffer is shared.

Buffer::Buffer | ( | Buffer && | rhs | ) |
| noexcept

Move constructor. Constant time.

Buffer::Buffer | ( | int | size | ) |
| explicitnoexcept

Create buffer of specified size.

Buffer::Buffer | ( | const char * | data,
|  | int | size
| ) |  |
| explicitnoexcept

Create buffer by copying the data.

References ipe::String::data(), and ipe::String::size().
