class Nexpose::Endpoint
This class represents each of the /NexposeReport/nodes/node/endpoints/endpoint elements in the Nexpose
Full XML document.
It provides a convenient way to access the information scattered all over the XML in attributes and nested tags.
Instead of providing separate methods for each supported property we rely on Ruby's method_missing
to do most of the work.
Public Class Methods
Accepts an XML node from Nokogiri::XML.
# File lib/nexpose/endpoint.rb, line 13 def initialize(xml_node) @xml = xml_node end
Public Instance Methods
Save some time with a meta attribute, e.g. 80/tcp (open)
# File lib/nexpose/endpoint.rb, line 35 def label "#{self.port}/#{self.protocol} (#{self.status})" end
This method is invoked by Ruby when a method that is not defined in this instance is called.
In our case we inspect the @method@ parameter and try to find the attribute, simple descendent or collection that it maps to in the XML tree.
# File lib/nexpose/endpoint.rb, line 59 def method_missing(method, *args) # We could remove this check and return nil for any non-recognized tag. # The problem would be that it would make tricky to debug problems with # typos. For instance: <>.potr would return nil instead of raising an # exception unless supported_tags.include?(method) super return end # First we try the attributes. In Ruby we use snake_case, but in XML # CamelCase is used for some attributes translations_table = { } method_name = translations_table.fetch(method, method.to_s) return @xml.attributes[method_name].value if @xml.attributes.key?(method_name) return nil end
This allows external callers (and specs) to check for implemented properties
# File lib/nexpose/endpoint.rb, line 48 def respond_to?(method, include_private=false) return true if supported_tags.include?(method.to_sym) super end
Each of the services associated with this endpoint. Returns an array of Nexpose::Service
objects
# File lib/nexpose/endpoint.rb, line 41 def services @xml.xpath('./services/service').collect { |xml_service| Service.new(xml_service) } end
