IrOBEXConnection

• java.lang.Object

Fields Summary
boolean	isClosed Indicates whether this connection has been closed
private javax.microedition.io.StreamConnection	conn Underlying connection.
private InputStream	input Input stream provided by the underlying connection.
private OutputStream	output Output stream provided by the underlying connection.

Constructors Summary
public IrOBEXConnection(javax.microedition.io.StreamConnection conn) Creates this connection using the underlying stream connection. param conn undelying connection object throws IOException if the connection can not be established this.conn = conn; input = conn.openInputStream(); output = conn.openOutputStream();

Methods Summary
public void	close() Closes this connection and the underlying connection. throws IOException if an I/O error occurs synchronized (this) { if (isClosed) { return; } isClosed = true; } input.close(); output.close(); conn.close();
public final int	getMaximumPacketSize() Returns the amount of data that can be successfully sent or received in a single read/write operation. return the maximum packet size, or zero if any size may be used return Configuration.getIntProperty("obex.packetLength.max", 0);
public javax.microedition.io.Connection	getUnderlyingConnection() Returns the underlying connection, or null if there is none. return underlying connection object return conn;
public int	read(byte[] inData) Reads the packet data into the specified buffer. param inData destination buffer throws IOException if an I/O error occurs throws NullPointerException if the specified buffer is null return number of bytes read if (isClosed) { throw new IOException("The connection is closed."); } if (inData == null) { throw new NullPointerException("Input buffer is null."); } int size = getMaximumPacketSize(); int len = inData.length; if (size == 0 || len <= size) { return input.read(inData, 0, len); } int off = 0; while (off < len) { int count = input.read(inData, off, Math.min(size, len - off)); if (count == 0) { break; } off += count; } return off;
public void	write(byte[] outData, int len) Transfer the len bytes from specified packet over the irda connection. param outData source buffer param len data length throws IOException if an I/O error occurs throws NullPointerException if the specified buffer is null if (isClosed) { throw new IOException("The connection is closed."); } if (outData == null) { throw new NullPointerException("Output buffer is null."); } int size = getMaximumPacketSize(); if (size == 0 || len <= size) { output.write(outData, 0, len); return; } int off = 0; while (off < len) { int count = Math.min(size, len - off); output.write(outData, off, count); off += count; }
