Instance Method Details

#call(value, item_type) ⇒ String

Check a value against our type constraints, and return the lexical string representation if it’s okay.

Parameters:

  • value (Integer) —

    the ruby value

  • item_type (Saxon::ItemType) —

    the item type

Returns:

  • (String) —

    the lexical string representation of the value

def call(value, item_type)
  integer_value = case value
  when ::Numeric
    value.to_i
  else
    Integer(LexicalStringConversion.validate(value, item_type, Patterns::INTEGER), 10)
  end
  raise Errors::RubyValueOutOfBounds.new(value, item_type) unless in_bounds?(integer_value)
  integer_value.to_s
end

#gte_min?(integer_value) ⇒ Boolean

Returns whether the Ruby integer is >= the lower bound of the range allowed for the XDM type

Parameters:

  • integer_value (Integer) —

    the ruby integer to check

Returns:

  • (Boolean) —

    whether the value is okay

def gte_min?(integer_value)
  return true if min.nil?
  integer_value >= min
end

#in_bounds?(integer_value) ⇒ Boolean

Returns whether the Ruby integer is within the range allowed for the XDM type

Parameters:

  • integer_value (Integer) —

    the ruby integer to check

Returns:

  • (Boolean) —

    whether the value is within bounds

def in_bounds?(integer_value)
  gte_min?(integer_value) && lte_max?(integer_value)
end

#lte_max?(integer_value) ⇒ Boolean

Returns whether the Ruby integer is <= the upper bound of the range allowed for the XDM type

Parameters:

  • integer_value (Integer) —

    the ruby integer to check

Returns:

  • (Boolean) —

    whether the value is okay
