    • isArrayOfNumbers

      public static boolean isArrayOfNumbers(com.fasterxml.jackson.databind.JsonNode arr)
      Determines if the supplied array contains all numeric values
      Parameters:
      arr - the array to be evaluated.
      Returns:
      true if the supplied array contains all numeric values. If arr is not an array, returns false.

    • isArrayOfStrings

      public static boolean isArrayOfStrings(com.fasterxml.jackson.databind.JsonNode arr)
      Determines if the supplied array contains all String values
      Parameters:
      arr - the array to be evaluated.
      Returns:
      true if the supplied array contains all String values. If arr is not an array, returns false.

    • compare

      public static boolean compare(com.fasterxml.jackson.databind.JsonNode left, com.fasterxml.jackson.databind.JsonNode right) throws EvaluateRuntimeException
      Default comparison function for $sort
      Parameters:
      left - string or number to be compared
      right - string or number to be compared
      Returns:
      true is left is greater than right
      Throws:
      EvaluateRuntimeException - if left and right cannot be converted to numbers

    • ensureArray

      public static com.fasterxml.jackson.databind.node.ArrayNode ensureArray(com.fasterxml.jackson.databind.JsonNode n)
      If n is an array, it will be returned untouched. Otherwise, return a singleton array containing the value
      Parameters:
      n - JsonNode being checked
      Returns:
      corresponding array made from the input n

    • push

      public static com.fasterxml.jackson.databind.node.ArrayNode push(com.fasterxml.jackson.databind.node.ArrayNode left, com.fasterxml.jackson.databind.JsonNode right)

      Parameters:
      left - first array to be merged
      right - second array to be merged
      Returns:
      merged array containing the elements of left then the elements of right
