Detailed Description

Iterate through all the liberties of a block.

Point 'p' must be occupied. Like GoBoard::LibertyIterator, but allows moves to be executed during the iteration (uses a copy of the liberty list, if required by the implementation).

Block::LibertyList GoBoard::LibertyCopyIterator::m_liberties [private]

Copy of liberty list.

Necessary, because if moves are played and undone while iterating over liberty list, the implementation of GoBoard does not guarantee, that the order of the block's liberty list is preserved.
