Class LSSerializerImpl

java.lang.Object
  org.apache.xml.serializer.dom3.LSSerializerImpl

All Implemented Interfaces:

org.w3c.dom.DOMConfiguration, org.w3c.dom.ls.LSSerializer

public final class LSSerializerImpl
extends java.lang.Object
implements org.w3c.dom.DOMConfiguration, org.w3c.dom.ls.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.

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.

canSetParameter

public boolean canSetParameter(java.lang.String name,
                               java.lang.Object value)

Checks if setting a parameter to a specific value is supported.

Specified by:

canSetParameter in interface org.w3c.dom.DOMConfiguration

Parameters:

name - A String containing the DOMConfiguration parameter name.

value - An Object specifying the value of the corresponding parameter.

Since:

DOM Level 3

See Also:

DOMConfiguration.canSetParameter(java.lang.String, java.lang.Object)

getParameter

public java.lang.Object getParameter(java.lang.String name)
                              throws org.w3c.dom.DOMException

This method returns the value of a parameter if known.

Specified by:

getParameter in interface org.w3c.dom.DOMConfiguration

Parameters:

name - A String containing the DOMConfiguration parameter name whose value is to be returned.

Returns:

Object The value of the parameter if known.

Throws:

org.w3c.dom.DOMException

See Also:

DOMConfiguration.getParameter(java.lang.String)

getParameterNames

public org.w3c.dom.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 org.w3c.dom.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 org.w3c.dom.DOMException

This method sets the value of the named parameter.

Specified by:

setParameter in interface org.w3c.dom.DOMConfiguration

Parameters:

name - A String containing the DOMConfiguration parameter name.

value - An Object contaiing the parameters value to set.

Throws:

org.w3c.dom.DOMException

See Also:

DOMConfiguration.setParameter(java.lang.String, java.lang.Object)

getDomConfig

public org.w3c.dom.DOMConfiguration getDomConfig()

Returns the DOMConfiguration of the LSSerializer.

Specified by:

getDomConfig in interface org.w3c.dom.ls.LSSerializer

Returns:

A DOMConfiguration object.

Since:

DOM Level 3

See Also:

LSSerializer.getDomConfig()

getFilter

public org.w3c.dom.ls.LSSerializerFilter getFilter()

Returns the DOMConfiguration of the LSSerializer.

Specified by:

getFilter in interface org.w3c.dom.ls.LSSerializer

Returns:

A LSSerializerFilter object.

Since:

DOM Level 3

See Also:

LSSerializer.getFilter()

getNewLine

public java.lang.String getNewLine()

Returns the End-Of-Line sequence of characters to be used in the XML being serialized. If none is set a default "\n" is returned.

Specified by:
