# This class represents a {YAML Mapping}[http://yaml.org/spec/1.1/#mapping].
#
# A Psych::Nodes::Mapping node may have 0 or more children, but must have
# an even number of children. Here are the valid children a
# Psych::Nodes::Mapping node may have:
#
# * Psych::Nodes::Sequence
# * Psych::Nodes::Mapping
# * Psych::Nodes::Scalar
# * Psych::Nodes::Alias
class Mapping < Psych::Nodes::Node
# Any Map Style
ANY = 0
# Block Map Style
BLOCK = 1
# Flow Map Style
FLOW = 2
# The optional anchor for this mapping
attr_accessor :anchor
# The optional tag for this mapping
attr_accessor :tag
# Is this an implicit mapping?
attr_accessor :implicit
# The style of this mapping
attr_accessor :style
###
# Create a new Psych::Nodes::Mapping object.
#
# +anchor+ is the anchor associated with the map or +nil+.
# +tag+ is the tag associated with the map or +nil+.
# +implicit+ is a boolean indicating whether or not the map was implicitly
# started.
