module Webgen
class Context
# Provides quick access to special nodes of the node chain of a context object.
module Nodes
# Return the node which represents the file into which everything gets rendered.
#
# This is normally the same node as #content_node but can differ in special cases. For
# example, when rendering the content of node called 'my.page' into the output of the node
# 'this.page', 'this.page' would be the #dest_node and 'my.page' would be the #content_node.
#
# The #dest_node is not included in the chain but can be set via the option +:dest_node+!
#
# The returned node should be used as source node for calculating relative paths to other nodes.
def dest_node
@options[:dest_node] || content_node
end
# Return the reference node, ie. the node which provided the original content for this context
# object.
#
# The returned node should be used, for example, for resolving relative paths.
def ref_node
@options[:chain][0]
end
# Return the node that is ultimately rendered.
#
# This node should be used, for example, for retrieving meta information.
