Method Details

getTypeInfoProvider

public TypeInfoProvider getTypeInfoProvider()

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

Returns:

a new TypeInfoProvider

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 elemName,
 SchemaType type,
 AttributeMap attributes,
 NamespaceMap namespaces,
 Location location,
 int properties)
                  throws XPathException

Notify the start of an element

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ContentHandlerProxy

Parameters:

elemName - the name of the element.

type - the type annotation of the element.

attributes - the attributes of this element

namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements

location - an object providing information about the module, line, and column where the node originated

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

Throws:

XPathException - if an error occurs
