Class SerializerTraceWriter
Writer
org.apache.xml.serializer.SerializerTraceWriter
public class SerializerTraceWriter
extends Writer
This class wraps the real writer, it only purpose is to send
CHARACTERTOSTREAM events to the trace listener.
Each method immediately sends the call to the wrapped writer unchanged, but
in addition it collects characters to be issued to a trace listener.
In this way the trace
listener knows what characters have been written to the output Writer.
There may still be differences in what the trace events say is going to the
output writer and what is really going there. These differences will be due
to the fact that this class is UTF-8 encoding before emiting the trace event
and the underlying writer may not be UTF-8 encoding. There may also be
encoding differences. So the main pupose of this class is to provide a
resonable facsimile of the true output.

SerializerTraceWriter
public SerializerTraceWriter(Writer out,
SerializerTrace tracer)
Constructor.
If the writer passed in is null, then this SerializerTraceWriter will
only signal trace events of what would have been written to that writer.
If the writer passed in is not null then the trace events will mirror
what is going to that writer. In this way tools, such as a debugger, can
gather information on what is being written out.
out
- the Writer to write to (possibly null)tracer
- the tracer to inform that characters are being written
close
public void close()
throws java.io.IOException
Flush the internal buffer and close the Writer
java.io.Writer.close()
flush
public void flush()
throws java.io.IOException
Flush the internal buffer and flush the Writer
java.io.Writer.flush()
write
public void write(String s)
throws IOException
Write a string.
s
- String to be written
write
public void write(chars[] ,
int start,
int length)
throws java.io.IOException
Write a portion of an array of characters.
start
- Offset from which to start writing characterslength
- Number of characters to write
write
public void write(int c)
throws IOException
Write a single character. The character to be written is contained in
the 16 low-order bits of the given integer value; the 16 high-order bits
are ignored.
Subclasses that intend to support efficient single-character output
should override this method.
c
- int specifying a character to be written.
