Detailed Description

A class that holds an untyped byte buffer.

Iterators and indexing give access to the underlying byte[] which is guaranteed to be contiguous and at least as large as size().

This is moveable, but not implicitly copyable. If you want to copy it use the .copy() method. If you want to move it use std::move().

Constructor & Destructor Documentation

com::softwareag::connectivity::buffer_t::buffer_t ( )
inline

Construct an empty buffer.

com::softwareag::connectivity::buffer_t::buffer_t ( size_t  n)
explicit

Construct a buffer with (at least) capacity for n items.

com::softwareag::connectivity::buffer_t::~buffer_t ( )
inline

Free the underlying buffer contents.

com::softwareag::connectivity::buffer_t::buffer_t ( buffer_t &&  other)
inline

Move constructor.

Other will be left as the empty buffer

Member Function Documentation

iterator com::softwareag::connectivity::buffer_t::begin ( )
inline

Forward iterator begin.

const_iterator com::softwareag::connectivity::buffer_t::begin ( ) const
inline

Forward const_iterator begin.

const_iterator com::softwareag::connectivity::buffer_t::cbegin ( ) const
inline

Forward const_iterator begin.

const_iterator com::softwareag::connectivity::buffer_t::cend ( ) const
inline

Forward const_iterator end.

void com::softwareag::connectivity::buffer_t::clear ( )

Free the underlying buffer;.

buffer_t com::softwareag::connectivity::buffer_t::copy ( ) const

Return a deep copy of this buffer.

bool com::softwareag::connectivity::buffer_t::empty ( ) const
inline

Returns true if the buffer is unallocated (size() == 0)

iterator com::softwareag::connectivity::buffer_t::end ( )
inline

Forward iterator end.

const_iterator com::softwareag::connectivity::buffer_t::end ( ) const
inline

Forward const_iterator end.

bool com::softwareag::connectivity::buffer_t::operator!= ( const buffer_t other) const
inline

Returns true if both buffers are different sizes or have different contents.

buffer_t& com::softwareag::connectivity::buffer_t::operator= ( buffer_t &&  other)
inline

Move assignment.

Other will be left as the empty buffer and our previous contents will be freed.

bool com::softwareag::connectivity::buffer_t::operator== ( const buffer_t other) const
inline

Returns true if both buffers are the same size and have the same contents.

uint8_t& com::softwareag::connectivity::buffer_t::operator[] ( size_t  n)
inline

Return a reference to the byte at the given offset.

If the offset is outside the buffer then throws std::runtime_error

const uint8_t& com::softwareag::connectivity::buffer_t::operator[] ( size_t  n) const
inline

Return a reference the byte at the given offset.

If the offset is outside the buffer then throws std::runtime_error

size_t com::softwareag::connectivity::buffer_t::size ( ) const
inline

Returns the size of the buffer.

void com::softwareag::connectivity::buffer_t::swap ( buffer_t &&  other)
inline

Swap the contents of this buffer and other.
