com.saxonica.serialize.SequenceWrapperPE

All Implemented Interfaces:

Result, Receiver

public class SequenceWrapperPE
extends SequenceWrapper

This class can be used in a push pipeline: it accepts any sequence as input, and generates a document in which the items of the sequence are wrapped by elements containing information about the types of the items in the input sequence.

This class adds to the superclass the ability to serialize maps.

Constructor Detail

SequenceWrapperPE

public SequenceWrapperPE(Receiver destination)

Create a sequence wrapper. This creates an XML representation of the items sent to destination in which the types of all items are made explicit

Parameters:

destination - the sequence being wrapped

Method Detail

open

public void open()
          throws XPathException

Description copied from class: SequenceReceiver

Start the output process

Specified by:

open in interface Receiver

Overrides:

open in class SequenceWrapper

Throws:

XPathException - if an error occurs

append

public void append(Item item,
          int locationId,
          int copyNamespaces)
            throws XPathException

Output an item (atomic value or node) to the sequence

Overrides:

append in class SequenceWrapper

Parameters:

item - the item to be appended

locationId - the location of the calling instruction, for diagnostics

copyNamespaces - if the item is an element node, this indicates whether its namespaces need to be copied. Values are NodeInfo.ALL_NAMESPACES, NodeInfo.LOCAL_NAMESPACES, NodeInfo.NO_NAMESPACES

Throws:

XPathException - if the operation fails
