Detailed Description

Class representing a general-use automatically managed/resized buffer.

In most respect, Buffer class is equivalent to std::vector<uint8_t> and is in fact uses it as a base class. In addition to that, it provides buf() and buf<T>() helper method for easier access to the underlying data (buf<T>() casts pointer to the requested class)

Constructor & Destructor Documentation

ndn::Buffer::Buffer

(

)

Creates an empty buffer.

Definition at line 38 of file buffer.cpp.

ndn::Buffer::Buffer ( size_t  size )

explicit

Creates a buffer with pre-allocated size.

Parameters

size	size of the buffer to be allocated

Definition at line 42 of file buffer.cpp.

ndn::Buffer::Buffer	(	const void *	buf,
		size_t	length
	)

Create a buffer by copying contents from a buffer.

Parameters

buf	const pointer to buffer
length	length of the buffer to copy

Definition at line 47 of file buffer.cpp.

template<class InputIterator >

ndn::Buffer::Buffer ( InputIterator  first, InputIterator  last  )

inline

Create a buffer by copying contents of the range [first, last)

Template Parameters

InputIterator

an InputIterator compatible with std::vector<uint8_t> constructor

Parameters

first	iterator to the first element to copy
last	iterator to the element immediately following the last element to copy

Definition at line 69 of file buffer.hpp.

Member Function Documentation

uint8_t* ndn::Buffer::get ( )

inline

Returns

pointer to the first byte of the buffer

Definition at line 77 of file buffer.hpp.

uint8_t* ndn::Buffer::buf ( )

inline

Returns

pointer to the first byte of the buffer

This is same as .get()

Definition at line 87 of file buffer.hpp.
