All Implemented Interfaces:

Closeable, Flushable, Appendable

Direct Known Subclasses:

ProtectedUTF8XMLWriter

public class MyUTF8XMLWriter
extends Writer

An XMLWriter that encodes characters in UTF-8. Methods are not synchronized: wrap this in a SyncXMLWriter if you need to use this concurrently from multiple threads. This version has been entirely retaken from com.jclark.xml.output.UTF8XMLWriter which took the lineSeparator from the system properties hence was not settable. Rewrote every line-separator expression as protected method.

writeUTF8

public void writeUTF8(byte[] buf,
                      int off,
                      int len)
               throws IOException

Throws:

IOException

write

public void write(char[] cbuf,
                  int off,
                  int len)
           throws IOException

Specified by:

write in class Writer

Throws:

IOException

write

public void write(char c)
           throws IOException

Throws:

IOException

write

public void write(String str)
           throws IOException

Overrides:

write in class Writer

Throws:

IOException

write

public void write(String str,
                  int off,
                  int len)
           throws IOException

Overrides:

write in class Writer

Throws:

IOException

writeRaw

protected void writeRaw(String str)
                 throws IOException

This method is the core writing mechanism. No other escape than the necessary ones for UTF-8. Calling it with < or > will probably invalidate the output xml.

Throws:

IOException

startElement

public void startElement(String name)
                  throws IOException

Throws:

public void startAttribute(String name)
                    throws IOException

Throws:

public void endAttribute()
                  throws IOException

Throws:

Throws:

IOException

newLine

public void newLine()
             throws IOException

Adds up a newLine as defined by the lineSeparator variable. This method is also called by any newLine printing as all newLines transmitted are escaped (at least the escaped ones).

Throws:

IOException
