Creating an object for communications with NEOS

Description

This function creates an object of class NeosComm that will contain all necessary information for dealing with HTTP requests to NEOS. This object will be needed in all requests to NEOS and hence must be created in advance of XML-RPC requests.

Usage

CreateNeosComm(curlopts = list(httpheader = c(`Content-Type` =
"text/xml", `User-Agent` = "R"), port = 3333), curlhandle =
getCurlHandle())

Arguments

Details

A list of valid curl options can be retrieved from listCurlOptions(). Please note, that the relevant HTTP-bodies within the requests will be created directly in the API-functions provided in this package and must not be provided as list elements in curloptions. However, if one accesses NEOS via a Proxy-Server, for instance, than the values for the relevant options must be set within the list-argument curlopts. The values of the returned object will be passed down to the function xml.rpc() which is utilised for all calls to the function Nfoo contained in this package. Hereby, foo signify the name of NEOS-API.

Value

An object of class NeosComm.

Inserting CDATA into XML-templates of NEOS

Description

With this function the information for XML-templates can be inserted. Ordinarily, one creates an object with the function NgetSolverTemplate() first and then inserts the requested CDATA fields of this XML-form with this function.

Usage

CreateXmlString(neosxml, cdatalist)

Arguments

Value

A character string containing the specified optimization problem, which can then be used in a call to NsubmitJob().

Create an instance of an XMLRPCServer object

Description

The XMLRPCServer class is a means to identify a string as the URL of an XML-RPC server. We can then use this to invoke a method provided by the server either via a call to xml.rpc or via an expression of the form server$methodName(arg1, arg2, ...).

The XMLRPCServerConnection class allows us to associate a CURLHandle object with an XML-RPC server. This connection is then used in each of the calls to that server. This allows us to reuse a single curl connection to the server and also slightly simplifies passing it to each call.

Usage

XMLRPCServer(url, curl = NULL,
class = if (!is.null(curl)) "XMLRPCServerConnection" else
  "XMLRPCServer", ..., .opts = list(...))

Arguments

Value

An object of class given by the value of class.

Invoke XML-RPC method from R

Description

This function can be used to invoke a method provided by an XML-RPC (remote procedure call) server. It can pass R objects in the request by serializing them to XML format and also converts the result back to R.

Usage

xml.rpc(url, method, ..., .args = list(...), .opts = list(),
        .defaultOpts = list(httpheader = c("Content-Type" = "text/xml"),
                            followlocation = TRUE,
                            useragent = useragent),
         .convert = TRUE, .curl = getCurlHandle(),
          useragent = "R-XMLRPC")

Arguments

Value

If .convert is a logical value and TRUE, an R object giving the result of the XML-RPC method invocation. If .convert is FALSE, a string giving the body of the response.

If .convert is a function, it is called with the body of the XML-RPC response as a string.
