The RequirementList
is used to hold the requirements being considered while resolving a set of gems.
The RequirementList
acts like a queue where the oldest items are removed first.
Creates a new RequirementList
.
# File rubygems/resolver/requirement_list.rb, line 15 def initialize @exact = [] @list = [] end

# File rubygems/resolver/requirement_list.rb, line 28 def add(req) if req.requirement.exact? @exact.push req else @list.push req end req end

# File rubygems/resolver/requirement_list.rb, line 62 def empty? @exact.empty? && @list.empty? end
Returns the oldest five entries from the list.
# File rubygems/resolver/requirement_list.rb, line 77 def next5 x = @exact[0,5] x + @list[0,5 - x.size] end
