This R package provides a client to access Web Feature Services (WFS) (http://www.opengeospatial.org/standards/wfs).
The client relies on the GDAL (http://www.gdal.org/) library and the rgdal (https://cran.r-project.org/package=rgdal) package, which should be installed first.
See examples in the fmi (http://www.github.com/rOpenGov/fmi) and the gisfin packages (http://www.github.com/rOpenGov/gisfin) how to inherit the abstract R6 classes (https://cran.r-project.org/package=R6) provided by the package.

Dispatches a WFS request, saves the response to a file and parses the file. The data can be converted using ogr2ogr of RGDAL. Provides a caching mechanism for subsequent queries on the same data.
rwfs::WFSClient -> WFSCachingClient
saveGMLFile()
WFSCachingClient$saveGMLFile(destFile)
loadGMLFile()
WFSCachingClient$loadGMLFile(fromFile)
listLayers()
WFSCachingClient$listLayers()
getLayer()
WFSCachingClient$getLayer(layer, ...)
clone()
The objects of this class are cloneable with this method.
WFSCachingClient$clone(deep = FALSE)
deepWhether to make a deep clone.

WFSRequest, WFSStreamingClient
The abstract method getURL must be overloaded in a subclass to provide a request URL to a WFS service.
rwfs::WFSRequest -> rwfs::WFSStreamingRequest -> WFSCachingRequest
getDataSource()
WFSCachingRequest$getDataSource()
clone()
The objects of this class are cloneable with this method.
WFSCachingRequest$clone(deep = FALSE)
deepWhether to make a deep clone.

An abstract class to represent OGC's WFS client in R. Other client classes in this package inherit this this class.
R6Class object.
new(request)This method is used to create object of this
class with request as the request object containing WFS
connection information and methods. NOTE: as this is abstract class,
you shouldn't be creating instances of it.
Set client's request object to request,
which must inherit from WFSRequest.
Not implemented in this abstract class, but it classes inheriting this class.

This class should be inherited and the abstract method getDataSource overloaded
in a subclass to provide a reference.
