Constructor & Destructor Documentation

Handle()

constexpr xentara::memory::Array::Handle::Handle ( )

constexprdefaultnoexcept

Default constructor.

This constructor creates an invalid handle. Do not attempt to use this handle, the associated memory may not be valid.

Member Function Documentation

offset()

constexpr auto xentara::memory::Array::Handle::offset ( ) const -> std::size_t

constexprnoexcept

Gets the offset within the array data.

operator++() [1/2]

auto xentara::memory::Array::Handle::operator++ ( ) -> Handle &

noexcept

Increments the handle by a one byte.

Attention

This can make the handle point to invalid data. It is your respoinsibility to ensure that the handle does not end up pointing outside of the array's data.

Returns

Returns a reference to this object

operator++() [2/2]

auto xentara::memory::Array::Handle::operator++ ( int  ) -> Handle

noexcept

Increments the handle by a one byte.

Attention

This can make the handle point to invalid data. It is your respoinsibility to ensure that the handle does not end up pointing outside of the array's data.

Returns

The old value of the handle

operator+=()

auto xentara::memory::Array::Handle::operator+= ( std::ptrdiff_t  offset ) -> Handle &

noexcept

Offsets the handle by a specific number of bytes.

Attention

This can make the handle point to invalid data. It is your respoinsibility to ensure that the handle does not end up pointing outside of the array's data.

Parameters

offset

The number of bytes to move the handle

Returns

Returns a reference to this object

operator--() [1/2]

auto xentara::memory::Array::Handle::operator-- ( ) -> Handle &

noexcept

Decrements the handle by a one byte.

Attention

This can make the handle point to invalid data. It is your respoinsibility to ensure that the handle does not end up pointing outside of the array's data.

Returns

Returns a reference to this object

operator--() [2/2]

auto xentara::memory::Array::Handle::operator-- ( int  ) -> Handle

noexcept

Decrements the handle by a one byte.

Attention

This can make the handle point to invalid data. It is your respoinsibility to ensure that the handle does not end up pointing outside of the array's data.

Returns

The old value of the handle

operator-=()

auto xentara::memory::Array::Handle::operator-= ( std::ptrdiff_t  offset ) -> Handle &

noexcept

Offsets the handle by a specific number of bytes.

Attention

This can make the handle point to invalid data. It is your respoinsibility to ensure that the handle does not end up pointing outside of the array's data.

Parameters

offset

The negative number of bytes to move the handle

Returns

Returns a reference to this object

operator<=>()

auto xentara::memory::Array::Handle::operator<=> ( const Handle &  rhs ) const -> auto=default

default

Comparison operator.

operator==()

auto xentara::memory::Array::Handle::operator== ( const Handle &  ) const -> bool=default

default

Comparison operator.
