Constructor & Destructor Documentation

public OutputStream::OutputStream ( Connection c ) [inline, private]

Construct an OutputStream which encodes the bits going to a Connection object. Parameters: c   the raw connection to use Definition at line 59 of file OutputStream.java.

public OutputStream::OutputStream ( java.io.OutputStream o ) [inline, private]

Construct an OutputStream which sends bits to an arbitrary inputstream. Parameters: o   the raw outputstream to use Definition at line 84 of file OutputStream.java.

Member Function Documentation

public void OutputStream::flush ( ) [inline, private]

Sends the total accumulated buffer of bytes over the connection. Empties the buffer ready for the next batch of bytes. Exceptions: MPSException   if there's a problem writing. Definition at line 235 of file OutputStream.java.

private void OutputStream::open ( ) [inline, private]

Causes the connection to the server to open, if it isn't already open. Exceptions: MPSException   from connection.getOutputStream() if there's a problem See also: org.hebe.mps.ConnectiongetOutputStream Definition at line 117 of file OutputStream.java. Referenced by flush().

public void OutputStream::resetBuffer ( ) [inline, private]

Resets our internal buffer to empty. Definition at line 74 of file OutputStream.java. Referenced by Server::Runnable::run().

private void OutputStream::setupBuffer ( ) [inline, private]

Creates and initialises a fresh StringBuffer in member variable buffer. Definition at line 68 of file OutputStream.java. Referenced by OutputStream(), flush(), and resetBuffer().

private void OutputStream::write ( int ch ) [inline, private]

Buffer up a single byte to send. The buffer is not flushed to the server until the flush() method is called. Parameters: ch   the byte to buffer up See also: org.hebe.mps.OutputStreamflush Definition at line 97 of file OutputStream.java. Referenced by flush(), writebool(), writechar(), writeint(), writelong(), and writestring().

public void OutputStream::writeReference ( Object o ) [inline, private]

Writes a reference to an MPS object to the remote end. Sends a canonical name for the object as a string. The remote end will then construct a proxy on the other side of the connection to make use of the reference that has been sent to it. Parameters: o   the MPS Interface to write Exceptions: MPSException   if there's a problem writing MPSException   if o is not being served by an instance of Server and o is not an instance of Proxy See also: org.hebe.mps.Proxy , org.hebe.mps.InputStreamreadReference Definition at line 198 of file OutputStream.java.

public void OutputStream::writebool ( boolean b ) [inline, private]

Writes a single boolean to the server. Parameters: b   the boolean to write Definition at line 154 of file OutputStream.java.

public void OutputStream::writechar ( char ch ) [inline, private]

Writes a single char to the server. Parameters: ch   the char to write Definition at line 179 of file OutputStream.java.

public void OutputStream::writefloat ( float f ) [inline, private]

Writes a single float to the server. Parameters: f   the float to write Exceptions: MPSException   if there's a problem writing Definition at line 224 of file OutputStream.java.

public void OutputStream::writeint ( int i ) [inline, private]

Writes a single int to the server. Parameters: i   the 32-bit signed value to write Definition at line 127 of file OutputStream.java. Referenced by Proxy::getOutputStream(), Server::Runnable::run(), and writefloat().

public void OutputStream::writelong ( long i ) [inline, private]

Writes a single long to the server. Parameters: i   the long to write Definition at line 163 of file OutputStream.java.

public void OutputStream::writestring ( String s ) [inline, private]

Writes a single java.lang.String to the server. Parameters: s   the string to write Definition at line 139 of file OutputStream.java. Referenced by writeReference().
