Detailed Description

Container representing a NCML request.

The real name of a NCMLContainer is the actual NCML request. When the access method is called the NCML request is made, the response cached if successfull, and the target response returned as the real container that a data handler would then open.

Constructor & Destructor Documentation

NCMLContainer::NCMLContainer	(	const string &	sym_name,
		const string &	xml_doc
	)

Creates an instances of NCMLContainer with the symbolic name and the xml document string.

The xml document is contained within the DHI, so must be passed in here.

The type of the container is ncml. This way we know to use the ncml handler for this container.

Parameters

sym_name	symbolic name representing this NCML container
ncml_doc	string of the xml document
