Resource from a non-physical file [message #1724390]

Hi,

Does a Resource always boil down to a physical file ?
In my case I have the content of a xml file that is stored in a java String.
Do I really need to save it on the disk and load the Resource from there, that way:

Resource resource = resourceSet.getResource(fileURI, true);

or is there a way to avoid saving on the disk ?

Thank you.

Aurel

You can load resourse from anything as long as there is a URI handler which knows how to open stream for your "anything". In one of my projects I used mem: protocol and a custom protocol handler to load models from in-memory resourses.

Hi

You can use ResourceSet.createResource to create the resource then load
it from a stream.

Thanks, something like that should work (inspired from the XMLProcessor):

InputSource inputSource = new InputSource(new StringReader(xmlContent));
		XMLResource resource = (XMLResource) resourceSet.createResource(URI.createFileURI("xml"));
		resource.load(inputSource, null);
