Overview

This class represents each of the detailedreport/severity/category/cwe/staticflaws/flaw elements in the Veracode 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.

  @xml = xml_flaw
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args) ⇒ Object

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.

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
  method_name = method.to_s
  return @xml.attributes[method_name].value if @xml.attributes.key?(method_name)

  return @xml.parent.parent[:cwename] if method == :cwename
end

Instance Method Details

#respond_to?(method, include_private = false) ⇒ Boolean

Returns:

  • (Boolean)
