public class SplitterServletOutputStreamImpl

extends javax.servlet.ServletOutputStream

A class to write the incomning response data synchronously in a ByteArrayOutputStream. The SplitterServletOutputSreamImpl wrappes the original response stream from the given HttpServletResponse object. If the container invokes the method getOutputStream oder getWriter of the response and an instance of this class is used to write in the written data will be saved independently in a seperate stream.

Constructor Summary

SplitterServletOutputStreamImpl(javax.servlet.http.HttpServletResponse response)
Constructs a new SplitterServletOutputStreamImpl that splits the response data into a seperate buffer.

Method Summary

void	close() Closes the original response output stream.
byte[]	getContent() Returns the content that is written into the original response stream as a byte array.
java.lang.String	getContentAsString() Returns the content that is written into the original response stream as a String.
void	write(byte[] b) Writes b.length bytes from the specified byte array to the original reponse output stream and synchronously into a local stream.
void	write(byte[] b, int off, int len) Writes len bytes from the specified byte array starting at offset off to the original reponse output stream and synchronously into a local stream.
void	write(int b) Writes the specified byte to the original reponse output stream and synchronously into a local stream

Constructor Detail

SplitterServletOutputStreamImpl

public SplitterServletOutputStreamImpl(javax.servlet.http.HttpServletResponse response)

Constructs a new SplitterServletOutputStreamImpl that splits the response data into a seperate buffer. The buffer is a ByteArrayOutputStream the original response content is also written into.

Parameters:

response - - the response its data should also be written in the seperated stream

Method Detail

getContent

public byte[] getContent()

Returns the content that is written into the original response stream as a byte array.

Returns:

the response content

getContentAsString

public java.lang.String getContentAsString()

Returns the content that is written into the original response stream as a String.

Returns:

the response content

write

public void write(int b)
           throws java.io.IOException

Writes the specified byte to the original reponse output stream and synchronously into a local stream

Specified by:

write in class java.io.OutputStream

Parameters:

b - - the byte.

Throws:

java.io.IOException - - if an I/O error occurs.

write

public void write(byte[] b)
           throws java.io.IOException

Writes b.length bytes from the specified byte array to the original reponse output stream and synchronously into a local stream.

Overrides:

write in class java.io.OutputStream

Parameters:

b - - the data.

Throws:

java.io.IOException - - if an I/O error occurs.

write(byte[] b, int off, int len)

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Writes len bytes from the specified byte array starting at offset off to the original reponse output stream and synchronously into a local stream.

Overrides:

write in class java.io.OutputStream

Parameters:

b - - the data.

off - - the start offset in the data.

len - - the number of bytes to write.

Throws:

java.io.IOException - - if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.

close

public void close()
           throws java.io.IOException

Closes the original response output stream. Before invoking close of the superclass the saved content is given to the guard class of the response.

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException - - if an I/O error occurs.
