## com.icl.saxon
Class IdentityTransformerHandler

    java.lang.Object
      com.icl.saxon.ContentEmitter
          com.icl.saxon.IdentityTransformerHandler

All Implemented Interfaces:
  org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.ext.LexicalHandler, TransformerHandler

public class IdentityTransformerHandler
extends ContentEmitter
implements 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
`void` `endDocument()` Override the behaviour of endDocument() in ContentEmitter
`Result` `getResult()` Get the output destination of the transformation
`java.lang.String` `getSystemId()` Get the systemId of the document
`Transformer` `getTransformer()` Get the Transformer used for this transformation
`void` `setResult(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 ContentEmitter

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 Transformer getTransformer()

  Get the Transformer used for this transformation

  Specified by:
    `getTransformer` in interface `TransformerHandler`
  Returns:
    `Transformer` associated with this `TransformerHandler`.

### setSystemId

    public void setSystemId(java.lang.String url)

  Set the SystemId of the document

  Specified by:
    `setSystemId` in interface `TransformerHandler`
  Parameters:
    `url` - Base URI for the source tree.

### getSystemId

    public java.lang.String getSystemId()

  Get the systemId of the document

  Specified by:
    `getSystemId` in interface `TransformerHandler`
  Returns:
    The systemID that was set with `TransformerHandler.setSystemId(java.lang.String)`.

### setResult

    public void setResult(Result result)

  Set the output destination of the transformation

  Specified by:
    `setResult` in interface `TransformerHandler`
  Parameters:
    `result` - A `Result` instance, should not be `null`.``

### getResult

    public Result getResult()

  Get the output destination of the transformation

### startDocument

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

  Override the behaviour of startDocument() in ContentEmitter

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

### endDocument

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

  Override the behaviour of endDocument() in ContentEmitter

  Specified by:
    `endDocument` in interface `org.xml.sax.ContentHandler`
  Overrides:
    `endDocument` in class `ContentEmitter`
  Throws:
    `org.xml.sax.SAXException`
