public class ApplyTemplatesAction
extends ItemFeed

This watch implements xsl:apply-templates in streaming mode. It watches for the nodes selected by the xsl:apply-templates instruction; when such a node is encountered, it locates the relevant (inverted) template, and activates it.

public ApplyTemplatesAction(Expression expression,
 ItemFeed result,
 XPathContext context)

Method Details

open

public void open(Terminator terminator)
          throws XPathException

Description copied from class: ItemFeed

Start evaluating the expression. The default implementation does nothing.

Overrides:

open in class ItemFeed

Parameters:

terminator - used to achieve early exit

Throws:

XPathException - if a dynamic error occurs

computeActualParams

public void computeActualParams(WithParam[] params)
                         throws XPathException

Throws:

XPathException

computeTunnelParams

public void computeTunnelParams(WithParam[] params)
                         throws XPathException

Throws:

XPathException

setActualParams

public void setActualParams(ParameterSet params)

setTunnelParams

public void setTunnelParams(ParameterSet params)

getLocalContext

protected XPathContext getLocalContext()

setMode

public void setMode(Component.M mode)

getMode

public Component getMode()

setWatchManager

public void setWatchManager(WatchManager watchManager)

startSelectedParentNode

public Receiver startSelectedParentNode(FleetingParentNode node,
 Location locationId)
                                 throws XPathException

Signal that an element or document node has been found that matches the selection that this Watch is looking for. This method is called by the WatchManager while processing the startElement or startDocument event that matches the selection.

Overrides:

startSelectedParentNode in class ItemFeed

Parameters:

node - the element or document node whose start event has been matched

locationId - the location associated with the element or document node (may be the location of the instruction that created it)

Returns:

a Receiver to be notified of all events starting with the startElement/startDocument event for the matched element, and ending with the endElement event for that element; or null if this feature is not required.

Throws:

XPathException - May be raised if a dynamic error occurs

getRule

protected Rule getRule(FleetingNode node)
                throws XPathException

Get the template rule matching a specific node

Parameters:

node - the node (in a streamed input document) to be matched

Returns:

the best-fit template rule used to process this node

Throws:

XPathException - if a dynamic error occurs

append

public void append(Item item)
            throws XPathException

Signal that a item (other than a streamed element) that matches the selection has been found.

Specified by:

append in interface Receiver

Specified by:

append in class ItemFeed

Parameters:

item - the item that was matched.

Throws:

XPathException - if the operation fails

endSelectedParentNode

public void endSelectedParentNode(Location locationId)
                           throws XPathException

Signal that the endElement event has occurred for the element whose startElement event caused the Watch to be activated.

Overrides:

endSelectedParentNode in class ItemFeed

Parameters:

locationId - the location of the node in the source, or of the instruction that created it

Throws:

ValidationException - May be raised if the constraint implemented by this Watch is violated @param locationId the location of the node in the source, or of the instruction that created it

XPathException - May be raised if a constraint implemented by this Watch is violated

close

public void close()
           throws XPathException

Description copied from class: ItemFeed

Finish evaluating the expression.

Specified by:

close in interface Receiver

Overrides:

close in class ItemFeed

Throws:

XPathException - if a dynamic error occurs
