public final class LSSerializerImpl
extends java.lang.Object
implements DOMConfiguration, LSSerializer

Implemenatation of DOM Level 3 org.w3c.ls.LSSerializer and org.w3c.dom.ls.DOMConfiguration. Serialization is achieved by delegating serialization calls to `org.apache.xml.serializer.ToStream` or one of its derived classes depending on the serialization method, while walking the DOM in DOM3TreeWalker.

Usage:
  **For internal use only**

Constructor Detail

### LSSerializerImpl

    public LSSerializerImpl()

  Constructor: Creates a LSSerializerImpl object. The underlying XML 1.0 or XML 1.1 org.apache.xml.serializer.Serializer object is created and initialized the first time any of the write methods are invoked to serialize the Node. Subsequent write methods on the same LSSerializerImpl object will use the previously created Serializer object.

Method Detail

### initializeSerializerProps

    public void initializeSerializerProps()

  Initializes the underlying serializer's configuration depending on the default DOMConfiguration parameters. This method must be called before a node is to be serialized.
  Usage:
    **For internal use only**

### getParameter

    public java.lang.Object getParameter(java.lang.String name)
                                  throws DOMException

  This method returns the value of a parameter if known.
  Specified by:
    getParameter in interface DOMConfiguration

    `name` - A String containing the DOMConfiguration parameter name whose value is to be returned.
  Returns:
    Object The value of the parameter if known.
  See Also:
    `DOMConfiguration.getParameter(java.lang.String)`

### getParameterNames

    public DOMStringList getParameterNames()

  This method returns a of the parameters supported by this DOMConfiguration object and for which at least one value can be set by the application
  Specified by:
    getParameterNames in interface DOMConfiguration
  Returns:
    DOMStringList A list of DOMConfiguration parameters recognized by the serializer
  See Also:
    `DOMConfiguration.getParameterNames()`

### setParameter

    public void setParameter(java.lang.String name,
                             java.lang.Object value)
                      throws DOMException

  This method sets the value of the named parameter.
  Specified by:
    setParameter in interface DOMConfiguration
  Parameters:
    `name` - A String containing the DOMConfiguration parameter name.
    `value` - An Object contaiing the parameters value to set.
  See Also:
    `DOMConfiguration.setParameter(java.lang.String, java.lang.Object)`

### getDomConfig

    public DOMConfiguration getDomConfig()

  Returns the DOMConfiguration of the LSSerializer.
  Specified by:
    getDomConfig in interface LSSerializer
  Returns:
    A DOMConfiguration object.
  Since:
    DOM Level 3
  See Also:
    `LSSerializer.getDomConfig()`

### getFilter

    public LSSerializerFilter getFilter()

  Returns the DOMConfiguration of the LSSerializer.
