BTGOEPConnection

• java.lang.Object

Fields Summary
private javax.microedition.io.StreamConnection	sock
private InputStream	is
private OutputStream	os

Constructors Summary
protected BTGOEPConnection(javax.microedition.io.StreamConnection sock) this.sock = sock; is = sock.openInputStream(); os = sock.openOutputStream();

Methods Summary
public void	close() Closes connection as well as the input stream and the output stream openning for this connection. throws IOException if I/O error. IOException ioe = null; try { is.close(); } catch (IOException e) { ioe = e; } try { os.close(); } catch (IOException e) { ioe = e; } try { sock.close(); } catch (IOException e) { ioe = e; } // catch IOException if any of the above call has thrown one if (ioe != null) { throw ioe; }
private final int	decodeLength16(byte[] buffer, int off) return ((((int)buffer[off]) & 0xFF) << 8) + (((int)buffer[off + 1]) & 0xFF);
public int	getMaximumPacketSize() Determines the amount of data (maximum packet size) that can be successfully sent in a single write operation. If the size of data is greater than the maximum packet size, then then only the first maximum packet size bytes of the packet are sent, and the rest will be discarded. return the maximum number of bytes that can be sent/received in a single call to read()/ write() without losing any data. return Configuration.getIntProperty( "obex.packetLength.max", 4096);
public javax.microedition.io.Connection	getUnderlyingConnection() Get underlying connection. return sock;
public int	read(byte[] inData) Reads the packet data into specified buffer. If the specified buffer length is 0, then 0 data will be read into this buffer, and the rest of packet data is lost. param inData the data array to fill with received bytes. exception IOException if a local or remote connection is closed or I/O error has happen. exception NullPointerException if the specified buffer is null. readFully(inData, 0, 3); // read header int packetLength = decodeLength16(inData, 1); if (packetLength < 3 || packetLength > inData.length) { throw new IOException("protocol error"); } readFully(inData, 3, packetLength - 3); return packetLength;
private final void	readFully(byte[] array, int offset, int size) Reads up to len bytes of data from the input stream into an array of bytes. param array the buffer into which the data is read. param offset the start offset in array b at which the data is written. param size the maximum number of bytes to read. exception IOException if an I/O error occurs. while (size != 0) { int count = is.read(array, offset, size); if (count == -1) { throw new IOException("read error"); } offset += count; size -= count; }
public void	write(byte[] outData, int len) param outData the buffer with the data to be sent. param len the number of bytes to be sent. exception IOException if a local or remote connection is closed or I/O error has happen. exception NullPointerException if the specified buffer is null. os.write(outData, 0, len); os.flush();
