#to_hashes(keys = []) ⇒ [Hash]

Create Hash Array

Examples:

teams   = es.teamList # Array of Team data
hash_a  = teams.to_hashes
=> [{:t_abbr=>"BOS", :t_name=>"Boston Celtics", :division=>"Atlantic", :conference=>"Eastern"} ... ]

Parameters:

def to_hashes(keys = [])
  return [] if empty?
  two_d = first.is_a? Array # Check for 2D array
  keys = checkKeys(keys, two_d ? first.size : size) # Determine keys
  return [Hash[keys.map.with_index { |key, idx| [key, self[idx]] }]] unless two_d # 1D Array
  map { |ary| Hash[keys.map.with_index { |key, idx| [key, ary[idx]] }] }          # 2D Array
end

#to_structs(keys = []) ⇒ [Struct]

Create Struct Array

Examples:

structs = teams.to_structs
=> [#<struct t_abbr="BOS", t_name="Boston Celtics", division="Atlantic", conference="Eastern"> ... ]

Parameters:

  • keys (Array) (defaults to: []) —

    Symbols to be used as field names

Returns:
