* Apply a visitor to an AST node or document.
|
|
*
|
|
* Walks through the tree (depth-first) starting from `node`, calling a
|
|
* `visitor` function with three arguments:
|
|
* - `key`: For sequence values and map `Pair`, the node's index in the
|
|
* collection. Within a `Pair`, `'key'` or `'value'`, correspondingly.
|
|
* `null` for the root node.
|
|
* - `node`: The current node.
|
|
* - `path`: The ancestry of the current node.
|
|
*
|
|
* The return value of the visitor may be used to control the traversal:
|
|
* - `undefined` (default): Do nothing and continue
|
|
* - `visit.SKIP`: Do not visit the children of this node, continue with next
|
|
* sibling
|
|
* - `visit.BREAK`: Terminate traversal completely
|
|
* - `visit.REMOVE`: Remove the current node, then continue with the next one
|
|
* - `Node`: Replace the current node, then continue by visiting it
|
|
* - `number`: While iterating the items of a sequence or map, set the index
|
|
* of the next step. This is useful especially if the index of the current
|
|
* node has changed.
|
|
*
|
|
* If `visitor` is a single function, it will be called with all values
|
|
* encountered in the tree, including e.g. `null` values. Alternatively,
|
|
* separate visitor functions may be defined for each `Map`, `Pair`, `Seq`,
|
|
* `Alias` and `Scalar` node. To define the same visitor function for more than
|
|
* one node type, use the `Collection` (map and seq), `Value` (map, seq & scalar)
|
|
* and `Node` (alias, map, seq & scalar) targets. Of all these, only the most
|
|
* specific defined one will be used for each node.
