Class ReceivingContentHandler

    java.lang.Object
      net.sf.saxon.event.ReceivingContentHandler

All Implemented Interfaces:
  ContentHandler, DTDHandler, LexicalHandler

Direct Known Subclasses:
  IdentityTransformerHandler, TemplatesHandlerImpl, TransformerHandlerImpl

    public class ReceivingContentHandler

extends Object
implements ContentHandler, LexicalHandler, DTDHandler

ReceivingContentHandler is a glue class that provides a standard SAX ContentHandler interface to a Saxon Receiver. To achieve this it needs to map names supplied as strings to numeric name codes, for which purpose it needs access to a name pool. The class also performs the function of assembling adjacent text nodes.

The class was previously named ContentEmitter.

If the input stream contains the processing instructions assigned by JAXP to switch disable-output-escaping on or off, these will be reflected in properties set in the corresponding characters events. In this case adjacent text nodes will not be combined.

Constructor Detail

### ReceivingContentHandler

    public ReceivingContentHandler()

  Create a ReceivingContentHandler and initialise variables

Method Detail

### reset

    public void reset()

  Set the ReceivingContentHandler to its initial state, except for the local name cache, which is retained

### setReceiver

    public void setReceiver(Receiver receiver)

  Set the receiver to which events are passed. ReceivingContentHandler is essentially a translator that takes SAX events as input and produces Saxon Receiver events as output; these Receiver events are passed to the supplied Receiver

  Parameters:
    `receiver` - the Receiver of events

### getReceiver

    public Receiver getReceiver()

  Get the receiver to which events are passed.

  Returns:
    the underlying Receiver

### setPipelineConfiguration

    public void setPipelineConfiguration(PipelineConfiguration pipe)

  Set the pipeline configuration

  Parameters:
    `pipe` - the pipeline configuration. This holds a reference to the Saxon configuration, as well as information that can vary from one pipeline to another, for example the LocationProvider which resolves the location of events in a source document

### getPipelineConfiguration

    public PipelineConfiguration getPipelineConfiguration()

  Get the pipeline configuration

  Returns:
    the pipeline configuration as supplied to `setPipelineConfiguration(PipelineConfiguration)`

### getConfiguration

    public Configuration getConfiguration()

  Get the Configuration object

  Returns:
    the Saxon configuration

### setIgnoreIgnorableWhitespace

    public void setIgnoreIgnorableWhitespace(boolean ignore)

  Set whether "ignorable whitespace" should be ignored. This method is effective only if called after setPipelineConfiguration, since the default value is taken from the configuration.

  Parameters:
    `ignore` - true if ignorable whitespace (whitespace in element content that is notified via the `ignorableWhitespace(char[], int, int)` method) should be ignored, false if it should be treated as ordinary text.

### isIgnoringIgnorableWhitespace

    public boolean isIgnoringIgnorableWhitespace()

  Determine whether "ignorable whitespace" is ignored. This returns the value that was set using `setIgnoreIgnorableWhitespace(boolean)` if that has been called; otherwise the value from the configuration.

  Returns:
    true if ignorable whitespace is being ignored

### startDocument

    public void startDocument()
                       throws SAXException

  Specified by:
    `comment` in interface `LexicalHandler`

    `SAXException`

### skippedEntity

    public void skippedEntity(String name)

                  throws SAXException

  Register the start of the DTD. Saxon ignores the DTD; however, it needs to know when the DTD starts and ends so that it can ignore comments in the DTD, which are reported like any other comment, but which are skipped because they are not part of the XPath data model
