Constructor Detail

NSDCHandler

public NSDCHandler(NSDCContext context)

Construct a serializer based on the specified context.

Method Detail

start

public java.io.InputStream start(java.lang.String source,
                                 CommonLogger logger)

Open a source file for reading, log a message on starting conversion, and return the input stream opened. If the source file is not found, an error message is logged and the NSDCException is thrown.

Specified by:

start in interface ConversionHandler

getDOMImplementation

public org.w3c.dom.DOMImplementation getDOMImplementation()

Return an implementation of Document Object Model.

Specified by:

getDOMImplementation in interface ConversionHandler

serialize

public void serialize(org.w3c.dom.Document document,
                      CommonLogger logger,
                      java.lang.String fileName,
                      java.lang.String extension,
                      boolean preserveSpace,
                      boolean indent,
                      int lineWidth)

Serialize the document to XML file constructing its name from the fileName parameter and the specified extension. If serialization fails, the NSDCException is thrown. The following context options are used in this method: "xml-indent" and "encoding".

Specified by:

serialize in interface ConversionHandler

Parameters:

document - a document to be serialized

logger - a logger used for logging messages

fileName - a name used as a template for the name of the output file

extension - an extension for the output file

preserveSpace - if true, the preserve space mode is used

indent - if true, the output will be indented (the value of the "xml-indent" option is used in this case)

lineWidth - a necessary width of output lines (0 means no text wrapping)
