    raise "wrong dateTime.iso8601 format " + str
  end
end

.double(str)

Converts a String to a Float

.fault(hash)

Converts the given hash to an FaultException object by passing the faultCode and faultString attributes of the Hash to FaultException.new

Raises an Exception if the given hash doesn't meet the requirements. Those requirements being:

2 keys
'faultCode' key is an Integer
'faultString' key is a String

# File 'lib/xmlrpc/parser.rb', line 139


def self.fault(hash)
  if hash.kind_of? Hash and hash.size == 2 and
    hash.has_key? "faultCode" and hash.has_key? "faultString" and
    hash["faultCode"].kind_of? Integer and hash["faultString"].kind_of? String

    XMLRPC::FaultException.new(hash["faultCode"], hash["faultString"])
  else
    raise "wrong fault-structure: #{hash.inspect}"
  end
end

.int(str)

Converts a String to an Integer

.struct(hash)

Converts the given hash to a marshalled object.

Returns the given hash if an exception occurs.

      hash.each {|key, value|
        obj.instance_variable_set("@#{ key }", value) if key =~ /^([a-zA-Z_]\w*)$/
