public TypeInfoProvider getTypeInfoProvider()

Get a TypeInfoProvider to provide type information for the current element or attribute event.

usesTypeAnnotations

public boolean usesTypeAnnotations()

Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events

Specified by:

usesTypeAnnotations in interface Receiver

Overrides:

usesTypeAnnotations in class ContentHandlerProxy

Returns:

true if the Receiver makes any use of this information. If false, the caller may supply untyped nodes instead of supplying the type annotation

startElement

public void startElement(NodeName nameCode,
                         SchemaType typeCode,
                         int locationId,
                         int properties)
                  throws XPathException

Notify the start of an element

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ContentHandlerProxy

Parameters:

nameCode - the name of the element.

typeCode - the type annotation of the element.

locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

properties - bit-significant properties of the element node. If there are no revelant properties, zero is supplied. The definitions of the bits are in class ReceiverOptions

Throws:

XPathException - if an error occurs
