Class LSSerializerImpl

java.lang.Object

org.apache.xml.serializer.dom3.LSSerializerImpl

All Implemented Interfaces:

DOMConfiguration, LSSerializer

public final class LSSerializerImpl
extends 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.

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(String name,
                               Object value)

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

Specified by:

canSetParameter in interface 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 Object getParameter(String name)
                    throws DOMException

This method returns the value of a parameter if known.

Specified by:

getParameter in interface 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:

DOMException

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(String name,
                         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.

Throws:

DOMException

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.

Specified by:

getFilter in interface LSSerializer

Returns:

A LSSerializerFilter object.

Since:

DOM Level 3

See Also:

LSSerializer.getFilter()

getNewLine

public 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:

getNewLine in interface LSSerializer

Returns:

A String containing the end-of-line character sequence used in serialization.

Since:

DOM Level 3

See Also:

LSSerializer.getNewLine()

setFilter

public void setFilter(LSSerializerFilter filter)

Set a LSSerilizerFilter on the LSSerializer. When set, the filter is called before each node is serialized which depending on its implemention determines if the node is to be serialized or not.

Specified by:

setFilter in interface LSSerializer

Parameters:

filter - A LSSerializerFilter to be applied to the stream to serialize.

Since:

DOM Level 3

See Also:

LSSerializer.setFilter(org.w3c.dom.ls.LSSerializerFilter)

setNewLine

public void setNewLine(String newLine)

Sets the End-Of-Line sequence of characters to be used in the XML being serialized. Setting this attribute to null will reset its value to the default value i.e. "\n".

Specified by:

setNewLine in interface LSSerializer

Parameters:

newLine - a String that is the end-of-line character sequence to be used in serialization.

Since:

DOM Level 3

See Also:

LSSerializer.setNewLine(java.lang.String)

Throws:

LSException - SERIALIZE_ERR: Raised if the LSSerializer was unable to serialize the node.

DOMException

Since:

DOM Level 3

Throws:

Throwable - if the DOM implementation does not implement Document.getXmlVersion()

getXMLEncoding

A String containing the encoding pseudo-attribute of the XMLDecl.

Throws:

Throwable - if the DOM implementation does not implement Document.getXmlEncoding()
