# 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:
|
|
#
|
|
# * Psych::Nodes::Sequence
|
|
# * Psych::Nodes::Mapping
|
|
# * Psych::Nodes::Scalar

# 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
|
|
# )
|
|
