This represents a YAML Document. This node must be a child of Psych::Nodes::Stream. A Psych::Nodes::Document must have one child, and that child may be one of the following:
The version of the YAML document
A list of tag directives for this document
Was this document implicitly created?
Is the end of the document implicit?
# File tmp/rubies/ruby-2.4.10/ext/psych/lib/psych/nodes/document.rb, line 45
def initialize version = [], tag_directives = [], implicit = false
super()
@version = version
@tag_directives = tag_directives
@implicit = implicit
@implicit_end = true
end
Create a new Psych::Nodes::Document object.
version is a list indicating the YAML version. tags_directives is a list of tag directive declarations implicit is a flag indicating whether the document will be implicitly started.
Example:
This creates a YAML document object that represents a YAML 1.1 document with one tag directive, and has an implicit start:
Psych::Nodes::Document.new( [1,1], [["!", "tag:tenderlovemaking.com,2009:"]], true )

def root

end
