Constructor Details

TByteBuffer

public TByteBuffer(ByteBuffer byteBuffer)
            throws TTransportException

Creates a new TByteBuffer wrapping a given NIO ByteBuffer.

Parameters:

byteBuffer - the NIO ByteBuffer to wrap.

Throws:

TTransportException - on error.

Method Details

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()

Description copied from class: TTransport

Opens the transport for reading/writing.

Specified by:

open in class TTransport

close

public void close()

Description copied from class: TTransport

Closes the transport.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in class TTransport

read

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

Description copied from class: TTransport

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

Specified by:

read in class TTransport

Parameters:

buf - 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

Parameters:

buf - The output data buffer

off - The offset to start writing from

len - The number of bytes to write

Throws:

TTransportException - if there was an error writing data
