## net.sf.saxon
Class IdentityTransformerHandler

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

All Implemented Interfaces:
  org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.ext.LexicalHandler, LocationProvider, org.xml.sax.Locator, SaxonLocator, javax.xml.transform.SourceLocator, javax.xml.transform.sax.TransformerHandler

public class IdentityTransformerHandler
extends ReceivingContentHandler
implements javax.xml.transform.sax.TransformerHandler

IdentityTransformerHandler implements the javax.xml.transform.sax.TransformerHandler interface. It acts as a ContentHandler and LexicalHandler which receives a stream of SAX events representing an input document, and performs an identity transformation passing these events to a Result

Constructor Summary
`protected` `IdentityTransformerHandler(Controller controller)` Create a IdentityTransformerHandler and initialise variables.

Method Summary
`javax.xml.transform.Result` `getResult()` Get the output destination of the transformation
`java.lang.String` `getSystemId()` Get the systemId of the document
`javax.xml.transform.Transformer` `getTransformer()` Get the Transformer used for this transformation
`void` `setResult(javax.xml.transform.Result result)` Set the output destination of the transformation
`void` `setSystemId(java.lang.String url)` Set the SystemId of the document
`void` `startDocument()` Override the behaviour of startDocument() in ReceivingContentHandler

Constructor Detail

### IdentityTransformerHandler

    protected IdentityTransformerHandler(Controller controller)

  Create a IdentityTransformerHandler and initialise variables. The constructor is protected, because the Filter should be created using newTransformerHandler() in the SAXTransformerFactory class

Method Detail

### getTransformer

    public javax.xml.transform.Transformer getTransformer()

  Get the Transformer used for this transformation

  Specified by:
    `getTransformer` in interface `javax.xml.transform.sax.TransformerHandler`

### setSystemId

    public void setSystemId(java.lang.String url)

  Set the SystemId of the document

  Specified by:
    `setSystemId` in interface `javax.xml.transform.sax.TransformerHandler`

### getSystemId

    public java.lang.String getSystemId()

  Get the systemId of the document

  Specified by:
    `getSystemId` in interface `javax.xml.transform.sax.TransformerHandler`
  Overrides:
    `getSystemId` in class `ReceivingContentHandler`
  Returns:
    A string containing the system identifier, or null if none is available.

### setResult

    public void setResult(javax.xml.transform.Result result)

  Set the output destination of the transformation

  Specified by:
    `setResult` in interface `javax.xml.transform.sax.TransformerHandler`

### getResult

    public javax.xml.transform.Result getResult()

  Get the output destination of the transformation

### startDocument

    public void startDocument()
                       throws org.xml.sax.SAXException

  Override the behaviour of startDocument() in ReceivingContentHandler

  Specified by:
    `startDocument` in interface `org.xml.sax.ContentHandler`
  Overrides:
    `startDocument` in class `ReceivingContentHandler`
  Throws:
    `org.xml.sax.SAXException`
