java.lang.Objectcom.saxonica.pull.UnconstructedParent
public abstract class UnconstructedParent
This class represents a virtual element node, the result of an element constructor that (in general) hasn't been fully evaluated. This is similar to a Closure, except that it is a NodeInfo rather than a Value. The object is capable of materializing the element if it is actually needed, but the aim is to avoid materializing the element wherever possible, at any rate not until its parent element is constructed so that this element can be built in-situ rather than being built as a standalone element and then later copied. This class is not currently used for elements that require schema validation.

For a node other than an element, the method returns null.
public void setSystemId(String systemId)
The system identifier is optional if the source does not get its data from a URL, but it may still be useful to provide one. The application can use a system identifier, for example, to resolve relative URIs and to include in error messages and warnings.

getTypedValue in interface Item<NodeInfo>XPathException - where no typed value is available, e.g. for

more efficient, especially in the common case where the value is expected to be a singleton.
