public interface DataConnection

The DataConnection interface provides methods for retrieving the underlying input and output streams of a data connection opened by issuing an AT command (such as ATD).

Method Summary

Methods

Modifier and Type	Method and Description
void	close() Closes this data connection.
java.io.InputStream	getInputStream() Gets this data connection's input stream.
java.io.OutputStream	getOutputStream() Gets this data connection's output stream.

Method Detail

close

void close()
           throws java.io.IOException

Closes this data connection.

When a connection has been closed, access to any of its methods that involve an I/O operation will cause an IOException to be thrown. Closing an already closed connection has no effect.

Closing a connection will also close the connection's InputStream and OutputStream.

Throws:

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

getInputStream

java.io.InputStream getInputStream()
                                   throws java.io.IOException

Gets this data connection's input stream. The same InputStream instance is returned upon subsequent calls.
Note that if this data connection's input stream has been previously closed this method returns that same closed input stream without attempting to re-open it.

Returns:

this data connection's input stream.

Throws:

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

getOutputStream

java.io.OutputStream getOutputStream()
                                     throws java.io.IOException

Gets this data connection's output stream. The same OutputStream instance is returned upon subsequent calls.
Note that if this data connection's output stream has been previously closed this method returns that same closed output stream without attempting to re-open it.

Returns:

this data connection's output stream.

Throws:

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