## net.sf.saxon.serialize
Class ImplicitResultChecker

    java.lang.Object
      net.sf.saxon.event.SequenceReceiver
          net.sf.saxon.event.ProxyReceiver
              net.sf.saxon.serialize.ImplicitResultChecker

All Implemented Interfaces:
  Result, Receiver

    public class ImplicitResultChecker

extends ProxyReceiver

This filter is inserted into the serializer pipeline when serializing an implicit XSLT result tree, that is, one that is created without use of xsl:result-document. Its main purpose is to check, if and only if the result destination is actually written to, that it does not conflict with an explicit result destination with the same URI. It also ensures that the output destination is opened before it is first written to.

Constructor Detail

### ImplicitResultChecker

    public ImplicitResultChecker(Receiver next,
                                 Controller controller)

  Create an ImplicitResultChecker. This is a filter on the output pipeline.

  Parameters:
    `next` - the next receiver on the pipeline
    `controller` - the controller of the XSLT transformation

Method Detail

### open

    public void open()
              throws XPathException

  Description copied from class: `ProxyReceiver`
  Start of event stream

  Specified by:
    `open` in interface `Receiver`
  Overrides:
    `open` in class `ProxyReceiver`
  Throws:
    `XPathException`

### startDocument

    public void startDocument(int properties)
                       throws XPathException

  Description copied from class: `ProxyReceiver`
  Start of a document node.

  Specified by:
    `startDocument` in interface `Receiver`
  Overrides:
    `startDocument` in class `ProxyReceiver`
  Parameters:
    `properties` - bit-significant integer indicating properties of the document node. The definitions of the bits are in class `ReceiverOptions`
  Throws:
    `XPathException`

### startElement

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

  Description copied from class: `ProxyReceiver`
  Notify the start of an element

  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`

### characters

    public void characters(CharSequence chars,
                           int locationId,

    `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 text node
  USE_CDATA
    Output as a CDATA section
  Throws:
    `XPathException`

### processingInstruction

    public void processingInstruction(String target,
                                      CharSequence data,
                                      int locationId,

  Description copied from class: `ProxyReceiver`
  Processing Instruction

  Specified by:
    `processingInstruction` in interface `Receiver`
  Overrides:
    `processingInstruction` in class `ProxyReceiver`
  Parameters:
    `target` - The PI name. This must be a legal name (it will not be checked).
    `data` - The data portion of the processing instruction
    `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` - Additional information about the PI.
  Throws:
    `XPathException`

### comment

    public void comment(CharSequence chars,
