True if the transport is open.

open

public void open()
          throws TTransportException
Description copied from class: TTransport
Opens the transport for reading/writing.

Specified by:
open in class TTransport
Throws:
TTransportException - if the transport could not be opened

read

public final int read(byte[] target,
                      int off,
                      int len)
               throws TTransportException
Description copied from class: TTransport
