Detailed Description

template<typename T>
struct FlowEngine::Buffer< T >

Holds a (mutable) non_owning pointer and a size Used to marshal memory buffers as arguments in a safely manner.

Constructor & Destructor Documentation

Buffer() [1/5]

template<typename T >

FlowEngine::Buffer< T >::Buffer ( )

default

Represents an empty buffer.

Buffer() [2/5]

template<typename T >

FlowEngine::Buffer< T >::Buffer ( T *  d, Size  s  )

inline

Construct a buffer from a (mutable) pointer and a size.

Buffer() [3/5]

template<typename T >

template<std::size_t N>
