#
# Implement an in-memory sort, relying on `to_a.sort!`
#
# Example:
#
# rel = [
# {:name => "Smith"},
# {:name => "Jones"}
# ]
# Sort.new(rel, Ordering[[:name, :asc]]).to_a
# # => [
# # {:name => "Jones"}
# # {:name => "Smith"},
# # ]
#
class Sort::InMemory < Cog
# @return [Enumerable] The operand
attr_reader :operand
# @return [Ordering] The ordering info
attr_reader :ordering
# Creates an Autonum instance
def initialize(operand, ordering)
@operand = operand
@ordering = ordering
end
# (see Cog#each)
def each(&block)
operand.to_a.sort!(&ordering.sorter).each(&block)
end
end # class Sort::InMemory
