Instance methods

<=>(other)

We compare UnwindDetails when choosing which state to unwind to. If two options have the same state_index we prefer the one most removed from a requirement that caused the conflict. Both options would unwind to the same state, but a grandparent option will filter out fewer of its possibilities after doing so - where a state is both a parent and a grandparent to requirements that have caused a conflict this is the correct behaviour. @param [UnwindDetail] other UnwindDetail to be compared @return [Integer] integer specifying ordering

all_requirements

@return [Array] array of all the requirements that led to the need for this unwind

requirements_unwound_to_instead

reversed_requirement_tree_index

@return [Integer] index of state requirement in reversed requirement tree (the conflicting requirement itself will be at position 0)

state_requirement

Source

sub_dependencies_to_avoid

@return [Array] array of sub-dependencies to avoid when choosing a new possibility for the state we've unwound to. Only relevant for non-primary unwinds

Source

unwinding_to_primary_requirement?

@return [Boolean] where the requirement of the state we're unwinding to directly caused the conflict. Note: in this case, it is impossible for the state we're unwinding to to be a parent of any of the other conflicting requirements (or we would have circularity)
