Package com.saxonica.ee.stream.feed

Class SimpleContentFeed

  • All Implemented Interfaces:
    javax.xml.transform.Result, Receiver
    public class SimpleContentFeed
extends AbsorptionFeed
    This class is used when a streaming template requests evaluation of a simple content constructor in streaming mode (that is, when it constructs a text, attribute, comment, or PI node based on the contents of the streamed document).

    The result of this Watch is a single string, constructed using the rules of "Constructing Simple Content" in the XSLT specification.

    The AdjacentTextNodeMergerFeed is used when the node is constructed as a result of a computation on the streamed data, for example xsl:value-of select="distinct-values(.//@price)". By contrast, a SimpleContentWatch is used when the streamed nodes are selected directly, for example xsl:value-of select=".//@price".

    Both a Feed and a Watch are needed because a simple content constructor operates on a sequence of nodes without simply atomizing the sequence.

      • makePendingItem

        protected AbsorptionFeed.PendingItem makePendingItem​(int sequenceNr,
                                                     FleetingParentNode node)
        Description copied from class: AbsorptionFeed
        Create a pending item (appropriate to the subclass) containing the data needed to compute the result value for one node in the streamed input sequence
        Specified by:
        makePendingItem in class AbsorptionFeed
        Parameters:
        sequenceNr - the sequence number of this node within a set of nested nodes
        node - the streamed input node
        Returns:
        the data needed to process this node

      • processGroundedItem

        protected Sequence processGroundedItem​(Item item)
                                throws XPathException
        Description copied from class: AbsorptionFeed
        Process a grounded item in the input sequence: either a streamed leaf node such as an attribute or text node, or an atomic value, or a non-streamed element or document node injected into the sequence for example by use of the comma operator.
        Specified by:
        processGroundedItem in class AbsorptionFeed
        Parameters:
        item - the grounded item
        Returns:
        the result of processing the grounded item
        Throws:
        XPathException - if a dynamic error occurs
