## net.sf.saxon.dom
Class DOMSender

    java.lang.Object
      net.sf.saxon.dom.DOMSender

All Implemented Interfaces:
  SourceLocator, LocationProvider, SaxonLocator, SourceLocationProvider, Locator

    public class DOMSender

extends Object
implements SaxonLocator, SourceLocationProvider

DOMSender.java: pseudo-SAX driver for a DOM source document. This class takes an existing DOM Document and walks around it in a depth-first traversal, calling a Receiver to process the nodes as it does so

Field Summary
`protected Node` | `root`
`protected String` | `systemId`

Constructor Summary
`DOMSender(Node startNode, Receiver receiver)` Create a DOMSender that will send events representing the nodes in a tree to a nominated receiver

Method Summary
`int` | `getColumnNumber()`
`int` | `getColumnNumber(long locationId)` Get the column number within the document, entity, or module containing a particular location
`int` | `getLineNumber()`
`int` | `getLineNumber(long locationId)` Get the line number within the document, entity or module containing a particular location
`String` | `getPublicId()`
`String` | `getSystemId()`
`String` | `getSystemId(long locationId)` Get the URI of the document, entity, or module containing a particular location
`void` | `send()` Walk a tree (traversing the nodes depth first).
`void` | `setSystemId(String systemId)` Set the systemId of the source document (which will also be used for the destination)

Field Detail

### root

    protected Node root

### systemId

    protected String systemId

Constructor Detail

### DOMSender

    public DOMSender(Node startNode,
                     Receiver receiver)

  Create a DOMSender that will send events representing the nodes in a tree to a nominated receiver

  Parameters:
    `startNode` - the root node of the tree to be send. Usually a document or element node.
    `receiver` - the object to be notified of the resulting events. The supplied Receiver must be initialized with a PipelineConfiguration.The PipelineConfiguration of the Receiver will be modified to set this DOMSender as its LocationProvider.

Method Detail

### setSystemId

    public void setSystemId(String systemId)

  Set the systemId of the source document (which will also be used for the destination)

  Parameters:
    `systemId` - the systemId of the source document

### send

    public void send()
              throws XPathException

  Walk a tree (traversing the nodes depth first).

  Throws:
    `IllegalStateException` - if the start node is of a node kind other than document, document fragment, element, text, comment, or processing instruction (for example, if it is an attribute node).
    `XPathException` - On any error in the document

### getColumnNumber

    public int getColumnNumber()

  Specified by:
    `getColumnNumber` in interface `SourceLocator`
  Specified by:
    `getColumnNumber` in interface `Locator`

### getLineNumber

    public int getLineNumber()

  Specified by:
    `getLineNumber` in interface `SourceLocator`
  Specified by:
    `getLineNumber` in interface `Locator`

### getPublicId

    public String getPublicId()

  Specified by:
    `getPublicId` in interface `SourceLocator`
  Specified by:
    `getPublicId` in interface `Locator`

### getSystemId

    public String getSystemId()

  Specified by:
    `getSystemId` in interface `SourceLocator`
  Specified by:
    `getSystemId` in interface `Locator`

### getSystemId

    public String getSystemId(long locationId)

  Description copied from interface: `LocationProvider`
  Get the URI of the document, entity, or module containing a particular location

  Specified by:
    `getSystemId` in interface `LocationProvider`
  Parameters:
    `locationId` - identifier of the location in question (as passed down the Receiver pipeline)
  Returns:
    the URI of the document, XML entity or module. For a SourceLocationProvider this will be the URI of the document or entity (the URI that would be the base URI if there were no xml:base attributes). In other cases it may identify the query or stylesheet module currently being executed.

### getLineNumber

    public int getLineNumber(long locationId)

  Description copied from interface: `LocationProvider`
  Get the line number within the document, entity or module containing a particular location

  Specified by:
    `getLineNumber` in interface `LocationProvider`
  Parameters:
    `locationId` - identifier of the location in question (as passed down the Receiver pipeline)
  Returns:
    the line number within the document, entity or module, or -1 if no information is available.

### getColumnNumber

    public int getColumnNumber(long locationId)

  Description copied from interface: `LocationProvider`
  Get the column number within the document, entity, or module containing a particular location

  Specified by:
    `getColumnNumber` in interface `LocationProvider`
  Parameters:
    `locationId` - identifier of the location in question (as passed down the Receiver pipeline)
  Returns:
    the column number within the document, entity, or module, or -1 if this is not available
