Examples of net.sf.saxon.om.Item

net.sf.saxon.om.Item
An Item is an object that can occur as a member of a sequence. It corresponds directly to the concept of an item in the XPath 2.0 data model. There are two kinds of Item: atomic values, and nodes.
This interface is part of the public Saxon API. As such (starting from Saxon 8.4), methods that form part of the stable API are labelled with a JavaDoc "since" tag to identify the Saxon release at which they were introduced.
Note: there is no method getItemType(). This is to avoid having to implement it on every implementation of NodeInfo. Instead, use the static method Type.getItemType(Item). @author Michael H. Kay @since 8.4
