  net.sf.saxon.evpull.StartElementEvent

All Implemented Interfaces:

PullEvent

public class StartElementEvent
extends Object
implements PullEvent

This is a PullEvent representing the start of an element node. It contains (or potentially contains) all the namespace declarations and attributes associated with the element.

Constructor Detail

StartElementEvent

public StartElementEvent(PipelineConfiguration pipe)

Create a Start Element Event

Parameters:

pipe - the pipeline configuration

Method Detail

setElementName

public void setElementName(NodeName elementName)

Set the nameCode of this element

Parameters:

elementName - the namecode of the element (its name as identified in the NamePool)

getElementName

public NodeName getElementName()

Get the nameCode of this element

Returns:

the nameCode representing the element's name

setTypeCode

public void setTypeCode(SchemaType typeCode)

Set the typeCode of this element

Parameters:

typeCode - the element's type annotation

getTypeCode

public SchemaType getTypeCode()

Get the typeCode of this element

Returns:

the element's type annotation

setLocalNamespaces

public void setLocalNamespaces(NamespaceBinding[] nscodes)

Set the namespaces that are locally declared (or undeclared) on this element

Parameters:

nscodes - integer array of namespace codes

addNamespace

public void addNamespace(NamespaceBinding nscode)
                  throws XPathException

Add a namespace code representing a locally declared namespace

Parameters:

nscode - a namespace code

Throws:

XPathException

getLocalNamespaces

public NamespaceBinding[] getLocalNamespaces()

Get the namespaces locally declared on this element

Returns:

an array of namespace codes

addAttribute

public void addAttribute(NodeInfo att)
                  throws XPathException

Add an attribute to the element node

Parameters:

att - the attribute to be added

Throws:

XPathException - in the event of a dynamic error, for example a duplicate attribute in XQuery

hasAttributes

public boolean hasAttributes()

Ask whether the element has any attributes

Returns:

true if the element has one or more attributes

getAttributeCount

public int getAttributeCount()

Ask how may attributes the element has

Returns:

the number of attributes that the element has

iterateAttributes

public Iterator iterateAttributes()

Get an iterator over the attributes of this element

Returns:

an iterator which delivers NodeInfo objects representing the attributes of this element

getAttribute

public NodeInfo getAttribute(int index)

Get the n'th attribute if there is one

Parameters:

index - the index of the attributes, starting from zero

Returns:

a NodeInfo representing the attribute, or null if there is no such attribute

namespaceFixup

public void namespaceFixup()

Perform namespace fixup. This is done after all the attributes and explicit namespaces have been added. Namespace fixup ensures that a namespace declaration is present for the element name and for every attribute name, and that the prefixes of the element and each attribute are consistent with the declared namespaces, changing any prefixes in the event of a conflict.

stripTypeAnnotations

public void stripTypeAnnotations()

Strip type annotations from the element and its attributes

getPipelineConfiguration

public PipelineConfiguration getPipelineConfiguration()

Get the PipelineConfiguration

Returns:

the PipelineConfiguration

setLocationId

public void setLocationId(int locationId)

Set the location associated with the event

Parameters:

locationId - a location identifier, to be interpreted by the locationProvider associated with the PipelineConfiguration

getLocationId

public int getLocationId()

Get the location associated with the event

Returns:

a location identifier, to be interpreted by the locationProvider associated with the PipelineConfiguration, or -1 if none is available
