public class DOMSerializerImpl
extends java.lang.Object
implements LSSerializer, DOMConfiguration

EXPERIMENTAL: Implemenatation of DOM Level 3 org.w3c.ls.LSSerializer by delegating serialization calls to XMLSerializer. LSSerializer provides an API for serializing (writing) a DOM document out in an XML document. The XML data is written to an output stream. During serialization of XML data, namespace fixup is done when possible as defined in DOM Level 3 Core, Appendix B.

Deprecated.

Description copied from interface: LSSerializer

The DOMConfiguration object used by the LSSerializer when serializing a DOM node.
In addition to the parameters recognized by the DOMConfiguration interface defined in [DOM Level 3 Core] , the DOMConfiguration objects for LSSerializer adds, or modifies, the following parameters:

"canonical-form"

true

[optional] Writes the document according to the rules specified in [Canonical XML]. In addition to the behavior described in " canonical-form" [DOM Level 3 Core] , setting this parameter to true will set the parameters "format-pretty-print", "discard-default-content", and "xml-declaration ", to false. Setting one of those parameters to true will set this parameter to false. Serializing an XML 1.1 document when "canonical-form" is true will generate a fatal error.

false

[required] (default) Do not canonicalize the output.

"discard-default-content"

true

[required] (default) Use the Attr.specified attribute to decide what attributes should be discarded. Note that some implementations might use whatever information available to the implementation (i.e. XML schema, DTD, the Attr.specified attribute, and so on) to determine what attributes and content to discard if this parameter is set to true.

false

[required]Keep all attributes and all content.

"format-pretty-print"

true

[optional] Formatting the output by adding whitespace to produce a pretty-printed, indented, human-readable form. The exact form of the transformations is not specified by this specification. Pretty-printing changes the content of the document and may affect the validity of the document, validating implementations should preserve validity.

false

[required] (default) Don't pretty-print the result.

"ignore-unknown-character-denormalizations"

true

[required] (default) If, while verifying full normalization when [XML 1.1] is supported, a character is encountered for which the normalization properties cannot be determined, then raise a "unknown-character-denormalization" warning (instead of raising an error, if this parameter is not set) and ignore any possible denormalizations caused by these characters.

false

[optional] Report a fatal error if a character is encountered for which the processor cannot determine the normalization properties.

"normalize-characters"

This parameter is equivalent to the one defined by DOMConfiguration in [DOM Level 3 Core] . Unlike in the Core, the default value for this parameter is true. While DOM implementations are not required to support fully normalizing the characters in the document according to appendix E of [XML 1.1], this parameter must be activated by default if supported.

"xml-declaration"

true

[required] (default) If a Document, Element, or Entity node is serialized, the XML declaration, or text declaration, should be included. The version (Document.xmlVersion if the document is a Level 3 document and the version is non-null, otherwise use the value "1.0"), and the output encoding (see LSSerializer.write for details on how to find the output encoding) are specified in the serialized XML declaration.

false

[required] Do not serialize the XML and text declarations. Report a "xml-declaration-needed" warning if this will cause problems (i.e. the serialized data is of an XML version other than [XML 1.0], or an encoding would be needed to be able to re-parse the serialized data).

Specified by:

getDomConfig in interface LSSerializer

setParameter

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

Deprecated.

DOM L3-EXPERIMENTAL: Setter for boolean and object parameters

Specified by:

setParameter in interface DOMConfiguration

Parameters:

name - The name of the parameter to set.

value - The new value or null if the user wishes to unset the parameter. While the type of the value parameter is defined as DOMUserData, the object type must match the type defined by the definition of the parameter. For example, if the parameter is "error-handler", the value must be of type DOMErrorHandler.

Throws:

DOMException - NOT_FOUND_ERR: Raised when the parameter name is not recognized.
NOT_SUPPORTED_ERR: Raised when the parameter name is recognized but the requested value cannot be set.
TYPE_MISMATCH_ERR: Raised if the value type for this parameter name is incompatible with the expected value type.

canSetParameter

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

Deprecated.

DOM L3-EXPERIMENTAL: Check if parameter can be set

Specified by:

canSetParameter in interface DOMConfiguration

Parameters:

name - The name of the parameter to check.

state - An object. if null, the returned value is true.

Returns:

true if the parameter could be successfully set to the specified value, or false if the parameter is not recognized or the requested value is not supported. This does not change the current value of the parameter itself.

getParameterNames

public DOMStringList getParameterNames()

Deprecated.

DOM Level 3 Core CR - Experimental. The list of the parameters supported by this DOMConfiguration object and for which at least one value can be set by the application. Note that this list can also contain parameter names defined outside this specification.

Specified by:

getParameterNames in interface DOMConfiguration

getParameter

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

Deprecated.

DOM L3-EXPERIMENTAL: Getter for boolean and object parameters

Specified by:

getParameter in interface DOMConfiguration

Parameters:

name - The name of the parameter.

Returns:

The current object associated with the specified parameter or null if no object has been associated or if the parameter is not supported.

Throws:

DOMException - NOT_FOUND_ERR: Raised when the parameter name is not recognized.

writeToString

public java.lang.String writeToString(Node wnode)
                               throws DOMException,
                                      LSException

Deprecated.

DOM L3 EXPERIMENTAL: Serialize the specified node as described above in the description of LSSerializer. The result of serializing the node is returned as a string. Writing a Document or Entity node produces a serialized form that is well formed XML. Writing other node types produces a fragment of text in a form that is not fully defined by this document, but that should be useful to a human for debugging or diagnostic purposes.

Specified by:

writeToString in interface LSSerializer

Parameters:

wnode - The node to be written.

Returns:

Returns the serialized data

Throws:

DOMException - DOMSTRING_SIZE_ERR: The resulting string is too long to fit in a DOMString.

LSException - SERIALIZE_ERR: Unable to serialize the node. DOM applications should attach a DOMErrorHandler using the parameter "error-handler" to get details on error.

setNewLine

public void setNewLine(java.lang.String newLine)

Deprecated.

DOM L3 EXPERIMENTAL: The end-of-line sequence of characters to be used in the XML being written out. The only permitted values are these:

null

Use a default end-of-line sequence. DOM implementations should choose the default to match the usual convention for text files in the environment being used. Implementations must choose a default sequence that matches one of those allowed by 2.11 "End-of-Line Handling".

CR

The carriage-return character (#xD).

CR-LF

The carriage-return and line-feed characters (#xD #xA).

LF

The line-feed character (#xA).

The default value for this attribute is null.

Specified by:

setNewLine in interface LSSerializer

getNewLine

public java.lang.String getNewLine()

Deprecated.

DOM L3 EXPERIMENTAL: The end-of-line sequence of characters to be used in the XML being written out. The only permitted values are these:

null

Use a default end-of-line sequence. DOM implementations should choose the default to match the usual convention for text files in the environment being used. Implementations must choose a default sequence that matches one of those allowed by 2.11 "End-of-Line Handling".

CR

The carriage-return character (#xD).

CR-LF

The carriage-return and line-feed characters (#xD #xA).

LF

The line-feed character (#xA).

The default value for this attribute is null.

Specified by:

getNewLine in interface LSSerializer

getFilter

public LSSerializerFilter getFilter()

Deprecated.

When the application provides a filter, the serializer will call out to the filter before serializing each Node. Attribute nodes are never passed to the filter. The filter implementation can choose to remove the node from the stream or to terminate the serialization early.

Specified by:

getFilter in interface LSSerializer

setFilter

public void setFilter(LSSerializerFilter filter)

Deprecated.

When the application provides a filter, the serializer will call out to the filter before serializing each Node. Attribute nodes are never passed to the filter. The filter implementation can choose to remove the node from the stream or to terminate the serialization early.

Specified by:

setFilter in interface LSSerializer

write

public boolean write(Node node,
                     LSOutput destination)
              throws LSException

Deprecated.

Serialize the specified node as described above in the general description of the LSSerializer interface. The output is written to the supplied LSOutput.
When writing to a LSOutput, the encoding is found by looking at the encoding information that is reachable through the LSOutput and the item to be written (or its owner document) in this order:

1. LSOutput.encoding,
2. Document.actualEncoding,
3. Document.xmlEncoding.

If no encoding is reachable through the above properties, a default encoding of "UTF-8" will be used.
If the specified encoding is not supported an "unsupported-encoding" error is raised.
If no output is specified in the LSOutput, a "no-output-specified" error is raised.

Specified by:

write in interface LSSerializer

Parameters:

node - The node to serialize.

destination - The destination for the serialized DOM.

Returns:

Returns true if node was successfully serialized and false in case the node couldn't be serialized.

Throws:

LSException - SERIALIZE_ERR: Raised if the LSSerializer was unable to serialize the node. DOM applications should attach a DOMErrorHandler using the parameter " error-handler" if they wish to get details on the error.

writeToURI

public boolean writeToURI(Node node,
                          java.lang.String URI)
                   throws LSException

Deprecated.

Serialize the specified node as described above in the general description of the LSSerializer interface. The output is written to the supplied URI.
When writing to a URI, the encoding is found by looking at the encoding information that is reachable through the item to be written (or its owner document) in this order:

1. Document.inputEncoding,
2. Document.xmlEncoding.

If no encoding is reachable through the above properties, a default encoding of "UTF-8" will be used.
If the specified encoding is not supported an "unsupported-encoding" error is raised.

Specified by:

writeToURI in interface LSSerializer

Parameters:

node - The node to serialize.

URI - The URI to write to.

Returns:

Returns true if node was successfully serialized and false in case the node couldn't be serialized.

Throws:

LSException - SERIALIZE_ERR: Raised if the LSSerializer was unable to serialize the node. DOM applications should attach a DOMErrorHandler using the parameter " error-handler" if they wish to get details on the error.
