Class NamePoolConverter

All Implemented Interfaces:
Result, Receiver

public class NamePoolConverter extends ProxyReceiver
This class is a filter that passes all Receiver events through unchanged, except that it changes namecodes to allow for the source and the destination using different NamePools. This is necessary when a stylesheet has been constructed as a general document (e.g. as the result of a transformation) and is passed to newTemplates() to be compiled as a stylesheet.

    • setUnderlyingReceiver

      public void setUnderlyingReceiver(Receiver receiver)
      Set the underlying emitter. This call is mandatory before using the Emitter. This version is modified from that of the parent class to avoid setting the namePool of the destination Receiver.
      Overrides:
      setUnderlyingReceiver in class ProxyReceiver
    • startElement

      public void startElement(int nameCode, int typeCode, int locationId, int properties) throws XPathException
      Output element start tag
      Specified by:
      startElement in interface Receiver
      Overrides:
      startElement in class ProxyReceiver
      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.
      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 - properties of the element node
      Throws:
      XPathException
    • namespace

      public void namespace(int namespaceCode, int properties) throws XPathException
      Handle a namespace
      Specified by:
      namespace in interface Receiver
      Overrides:
      namespace in class ProxyReceiver
      Parameters:
      namespaceCode - an integer: the top half is a prefix code, the bottom half a URI code. These may be translated into an actual prefix and URI using the name pool. A prefix code of zero represents the empty prefix (that is, the default namespace). A URI code of zero represents a URI of "", that is, a namespace undeclaration.
      properties - The most important property is REJECT_DUPLICATES. If this property is set, the namespace declaration will be rejected if it conflicts with a previous declaration of the same prefix. If the property is not set, the namespace declaration will be ignored if it conflicts with a previous declaration. This reflects the fact that when copying a tree, namespaces for child elements are emitted before the namespaces of their parent element. Unfortunately this conflicts with the XSLT rule for complex content construction, where the recovery action in the event of conflicts is to take the namespace that comes last. XSLT therefore doesn't recover from this error: it sets the REJECT_DUPLICATES flag, and this is treated as a hard error.
      Throws:
      XPathException
    • attribute

      public void attribute(int nameCode, int typeCode, CharSequence value, int locationId, int properties) throws XPathException
      Handle an attribute
      Specified by:
      attribute in interface Receiver
      Overrides:
      attribute in class ProxyReceiver
      Parameters:
      nameCode - The name of the attribute, as held in the name pool
      typeCode - The type of the attribute, as held in the name pool
      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 value. The following bits are defined:
      DISABLE_ESCAPING
      Disable escaping for this attribute
      NO_SPECIAL_CHARACTERS
      Attribute value contains no special characters
      Throws:
      XPathException
