Class ConfXMLParamToXML

Object

com.tailf.util.ConfXMLParamToXML

public class ConfXMLParamToXML
extends Object

Utility class to transform ConfXMLParam[] which represents a XML-fragment to a equivalent DOM (org.w3c.dom.Document) or to a string XML representation.

A fragment refer to part of a XML document that may be useful to use interchange in the absence of the rest of the XML document.

A fragment must be well-balanced and may or may not contain a surrounding root element. In either case a root element will always be created and it will always be the documents direct descendant node.

The parent tag may be supplied or omitted. If omitted a root element will be created with the name "fragment" without any namespace.

  <fragment>
   ...
  </fragment>

Method Details

clear

public void clear()

Clears the state of the instance of this class which permits multiple invocation of toXML(ConfXMLParam[],boolean).

toXML

public Document toXML(ConfXMLParam[] param,
 boolean includeEmpty)
               throws ConfException

Transforms the supplied parameter ConfXMLParam[] to a document (Document).

The root tag which encloses the structure will be set to a dummy tag fragment.

  <fragment>
   ...
  </fragment>
 

If another root tag is desired use the method toXML(ConfXMLParam[],String,String) where root tag name and namespace uri string could be supplied and will be the root Node of the returning Document.

Parameters:

param - The target array to be converted

includeEmpty - Include empty leaf values as ConfNoExists.toString()

Returns:

The resulting Document

Throws:

ConfException - If some error occurred

toXML

public Document toXML(ConfXMLParam[] param)
               throws ConfException

Transforms the supplied parameter ConfXMLParam[] to a document (Document).

The root tag which encloses the structure will be set to a dummy tag fragment.

  <fragment>
   ...
  </fragment>
 

If another root tag is desired use the method toXML(ConfXMLParam[],String,String) where root tag name and namespace uri string could be supplied and will be the root Node of the Document.

Excludes tags with empty leaf values from the document.

Parameters:

param - The source ConfXMLParam[] array to be converted to the equivalent document

Returns:

The resulting Document

Throws:

ConfException - If some error occurred

toXML

public Document toXML(ConfXMLParam[] param,
 String parentNode,
 String parentURI,
 boolean includeEmpty)
               throws ConfException

Transforms the supplied parameter ConfXMLParam[] to a document (Document).

Parameters:

param - The source ConfXMLParam[] to be converted to the equivalent document

parentNode - the parent tag that should be the the parent node of the source array.

parentURI - the namespace uri that the parentNode belongs to

includeEmpty - Include empty leaf values as ConfNoExists.toString()

Throws:

ConfException - if error occurred

toXML

public Document toXML(ConfXMLParam[] param,
 String parentNode,
 String parentURI)
               throws ConfException

Transforms the supplied ConfXMLParam[] to a document (Document). Excludes tags with empty leaf values from the resulting document.

Parameters:

param - The source ConfXMLParam structure (tag value array) to be converted to a document

parentNode - the parent tag that should be the the parent node of the source array.

parentURI - the namespace uri that the parentNode belongs to

Throws:

ConfException - if a error occurred

serialize

public void serialize(Document doc,
 OutputStream out)
               throws ConfException

Flushes the source document doc to the target out.

Parameters:

doc - The source document

out - The destination stream

Throws:

ConfException - if occurred while flushing the document

serialize

public void serialize(Document doc,
 Writer out)
               throws ConfException

Flushes the source document doc to the target out

Parameters:

doc - The source document

out - The destination writer

Throws:

ConfException - if occurred while flushing the document
