Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

A descent processor. This allows the context to descend into the children of the node as needed. This does not descend into block nodes by default, due to a design decision - that has to be handled by another processor.

Instance Method Details

#process_root(node) ⇒ Parser::Node::Root

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Processes the root node. This updates the root node with an updated list of children that have been accepted.

Parameters:

• node (Parser::Node::Root)

Returns:

• (Parser::Node::Root)

def process_root(node)
  node.update(children: node.children.map { |c| accept(c) }.compact)
