Detailed Description

An iterator for the const Chunk's 3D block data.

This iterator allows for range-based for loops and standard const iterator operations over the 3D block data stored within a Chunk. It provides a linear interface to traverse the 3D grid of blocks, enabling sequential immutable access to the elements stored in the chunk.

Constructor & Destructor Documentation

ConstIterator()

mcpp::Chunk::ConstIterator::ConstIterator ( pointer  ptr )

inline

Constructs an iterator at the given pointer position.

Parameters

ptr	Pointer to the position in the height array.

Member Function Documentation

operator*()

reference mcpp::Chunk::ConstIterator::operator* ( ) const

inline

Dereference the iterator to access the value at the current position.

Returns

Reference to the current element.

operator++() [1/2]

ConstIterator& mcpp::Chunk::ConstIterator::operator++ ( )

inline

Pre-increment operator. Advances the iterator to the next position.

Returns

Reference to the updated iterator.

operator++() [2/2]

ConstIterator mcpp::Chunk::ConstIterator::operator++ ( int  )

inline

Post-increment operator. Advances the iterator to the next position.

Parameters

int	Unused dummy parameter to differentiate from prefix increment.

Returns

Iterator to the original position before incrementing.

operator->()

pointer mcpp::Chunk::ConstIterator::operator-> ( )

inline

Access the pointer to the current element.

Returns

Pointer to the current element.

Friends And Related Function Documentation

operator!=

bool operator!= ( const ConstIterator &  a, const ConstIterator &  b  )

friend

Inequality comparison operator.

Parameters

a	First iterator to compare.
b	Second iterator to compare.

Returns

true if iterators point to different positions, false otherwise.

operator==

bool operator== ( const ConstIterator &  a, const ConstIterator &  b  )

friend

Equality comparison operator.

Parameters

a	First iterator to compare.
b	Second iterator to compare.

Returns

true if both iterators point to the same position, false otherwise.
