public class SSLOutputStream

extends java.io.OutputStream

This is the OutputStream which is returned by SSLTransport.getOutputStream. It is public to allow the application to control buffering.

To enable SSL/TLS layer buffering use code like for example:

 SSLSocket socket = new SSLSocket(...);
 SSLOutputStream out = (SSLOutputStream)socket.getOutputStream();
 out.setAutoFlush(false);
 // data written to out will now be buffered
 out.write(1);
 out.write(2);
 out.flush();

setAutoFlush(boolean), SSLTransport.getOutputStream()

Method Summary

void	close() Closes this output stream and releases any system resources associated with this stream.
void	flush() Flushes this output stream and forces any buffered output bytes to be written out.
boolean	getAutoFlush() Get the autoflush value.
void	setAutoFlush(boolean value) Control the SSL layer buffering.
void	write(byte[] b) Writes b.length bytes from the specified byte array to this output stream.
void	write(byte[] b, int off, int len) Writes len bytes from the specified byte array starting at offset off to this output stream.
void	write(int b) Writes the specified byte to this output stream.

Method Detail

setAutoFlush

public void setAutoFlush(boolean value)

Control the SSL layer buffering. If set to true (the default) each write call will automatically cause a flush, i.e. an SSLMessage to be sent. If set to false data will be buffered and an SSLMessage will only be sent if the buffer is full (16k) or flush() is called. This will effectively save you the need for external buffering.

Note that buffering is only available when SSL is active, i.e. not before the handshake has been performed. Also note that you must call flush when autoflush is disabled to be sure data is sent.

getAutoFlush

public boolean getAutoFlush()

Get the autoflush value. True by default.

write

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

Writes the specified byte to this output stream.

Overrides:

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 this output stream.

Overrides:

write in class java.io.OutputStream

Parameters:

b - the data.

Throws:

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

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 this output 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.

flush

public void flush()
           throws java.io.IOException

Flushes this output stream and forces any buffered output bytes to be written out.

Overrides:

flush in class java.io.OutputStream

Throws:

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

close

public void close()
           throws java.io.IOException

Closes this output stream and releases any system resources associated with this stream. A close_notify alert is also sent to inform the peer that everything worked well and that he also could cache this session.

Overrides:

close in class java.io.OutputStream

Throws:

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