Examples of net.sf.saxon.event.SequenceOutputter

net.sf.saxon.event.SequenceOutputter
This outputter is used when writing a sequence of atomic values and nodes, that is, when xsl:variable is used with content and an "as" attribute. The outputter builds the sequence and provides access to it. (It isn't really an outputter at all, it doesn't pass the events to anyone, it merely constructs the sequence in memory and provides access to it). Note that the event sequence can include calls such as startElement and endElement that require trees to be built. If nodes such as attributes and text nodes are received while an element is being constructed, the nodes are added to the tree. Otherwise, "orphan" nodes (nodes with no parent) are created and added directly to the sequence.
This class is not used to build temporary trees. For that, the ComplexContentOutputter is used.
