Detailed Description

General-purpose automatically managed/resized buffer.

In most respect, the Buffer class is equivalent to a std::vector<uint8_t>, and it in fact uses the latter as a base class. In addition to that, it provides the get<T>() helper method that automatically casts the returned pointer to the requested type.

Constructor & Destructor Documentation

ndn::Buffer::Buffer ( )

default

Creates an empty Buffer.

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 40 of file buffer.cpp.

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

Creates a Buffer by copying contents from a raw buffer.

Parameters

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

Definition at line 45 of file buffer.cpp.

template<class InputIt >

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

inline

Creates a Buffer by copying the elements of the range [first, last)

Parameters

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

Definition at line 64 of file buffer.hpp.
