Method Detail

fill

public void fill(TTransport inTrans,
                 int length)
          throws TTransportException

Throws:

TTransportException

close

public void close()

Description copied from class: TTransport

Closes the transport.

Specified by:

close in class TTransport

isOpen

public boolean isOpen()

Description copied from class: TTransport

Queries whether the transport is open.

Specified by:

isOpen in class TTransport

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:

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

Reads up to len bytes into buffer buf, starting att offset off.

Specified by:

read in class TTransport

Parameters:

target - Array to read into

off - Index to start reading at

len - Maximum number of bytes to read

Returns:

The number of bytes actually read

Throws:

TTransportException - if there was an error reading data

write

public void write(byte[] buf,
                  int off,
                  int len)
           throws TTransportException

Description copied from class: TTransport

Writes up to len bytes from the buffer.

Specified by:

write in class TTransport

Description copied from class: TTransport

Consume len bytes from the underlying buffer.

Overrides:

consumeBuffer in class TTransport

getBuffer

public final byte[] getBuffer()

Description copied from class: TTransport
