Instance Method Details

#interpret(input, parent, root, _path) ⇒ Array

Apply selector to each value in the current node and return result.

The result is an Array containing all results of evaluating the CurrentNode’s selector (if any.)

If the selector extracted values from nodes such as strings, numbers or nil/null, these will be included in the array. If the selector did not match any node, the array may be empty. If there was no selector, then the current input node is returned in the array.

Parameters:

  • input (Array, Hash) —

    the results of processing so far

  • parent (Array, Hash) —

    parent of the input object

  • root (Array, Hash) —

    the entire input

  • _path (Array) —

    ignored

Returns:

  • (Array) —

    Node List containing all results from evaluating this node’s selectors.
