This is a class that represents a handle to an internal C-level data structure provided by libcurl to perform multiple HTTP requests in a single operation and process the responses in an inter-leaved fashion, i.e. a chunk from one, followed by a chunk from another.
Objects of this class contain not only a reference to the
internal C-level data structure, but also have a list
of the CURLHandle-class objects
that represent the individual HTTP requests that make up
the collection of concurrent requests.
These are maintained for garbage collection reasons.
Essentially, the data in objects of this class are for internal use; this is an opaque class in R.
The constructor function getCurlMultiHandle
is the only way to create meaningful instances of this class.
ref:Object of class "externalptr". This is
a reference to the instance of the libcurl data structure
CURLM pointer.
subhandles:Object of class "list".
This is a list of CURLHandle-class
instances that have been push()ed onto the
multi-handle stack.
