We manage a set of attributes. Each attribute has a symbol name and a bit value.
Returns a string representation of bitmap
# File rdoc/markup/attributes.rb, line 46 def as_string bitmap return 'none' if bitmap.zero? res = [] @name_to_bitmap.each do |name, bit| res << name if (bitmap & bit) != 0 end res.join ',' end
Returns a unique bit for name
# File rdoc/markup/attributes.rb, line 29 def bitmap_for name bitmap = @name_to_bitmap.assoc name unless bitmap then bitmap = @next_bitmap @next_bitmap <<= 1 @name_to_bitmap << [name, bitmap] else bitmap = bitmap.last end bitmap end
yields each attribute name in bitmap
# File rdoc/markup/attributes.rb, line 60 def each_name_of bitmap return enum_for __method__, bitmap unless block_given? @name_to_bitmap.each do |name, bit| next if bit == @special yield name.to_s if (bitmap & bit) != 0 end end
