JDOM parsing and memory

SAXBuilder builder = new SAXBuilder();
Document doc = builder.build(billFile);
Element root = doc.getRootElement();

I am trying to parse an xml file using JDOM. I am using above lines to create the document from billFile which is a File object. At this point,
doc is in memory. Does it means it holds entire document in memory or it only holds some information, pulls it as and when required.
please clarify

It's all in memory. In other words, holding a reference to a JDOM document built from an XML file of 3 megabytes will take at least 3 megabytes of memory ("at least" because the object structure takes more space than the raw data).

There will be no reference in this case. Everything will be stored in memory.
