close
public void close()
Description copied from class:TTransport
Closes the transport.- Specified by:
close
in classTTransport
-
isOpen
public boolean isOpen()
Description copied from class:TTransport
Queries whether the transport is open.- Specified by:
isOpen
in classTTransport
- Returns:
- 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:

consumeBuffer
public final void consumeBuffer(int len)
Description copied from class:TTransport
Consume len bytes from the underlying buffer.- Overrides:
consumeBuffer
in classTTransport
-
getBuffer
public final byte[] getBuffer()
