The base class for any Node
in a YAML parse tree. This class should never be instantiated.
Create a new Psych::Nodes::Node
# File psych/lib/psych/nodes/node.rb, line 33 def initialize @children = [] end
# File psych/lib/psych/nodes/node.rb, line 67 def alias?; false; end
# File psych/lib/psych/nodes/node.rb, line 68 def document?; false; end
Iterate over each node in the tree. Yields each node to block
depth first.
# File psych/lib/psych/nodes/node.rb, line 40 def each &block return enum_for :each unless block_given? Visitors::DepthFirst.new(block).accept self end
# File psych/lib/psych/nodes/node.rb, line 69 def mapping?; false; end
# File psych/lib/psych/nodes/node.rb, line 70 def scalar?; false; end
# File psych/lib/psych/nodes/node.rb, line 71 def sequence?; false; end
# File psych/lib/psych/nodes/node.rb, line 72 def stream?; false; end
Convert this node to Ruby.
