Constructor Detail

### TypedContentHandler

    public TypedContentHandler()

Method Detail

### getTypeInfoProvider

    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(int nameCode,
                             int 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` - integer code identifying the name of the element within the name pool.
    `typeCode` - integer code identifying the element's type within the name pool. The value -1 indicates the default type, xs:untyped.
    `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`
