Constructor Detail

TMemoryBuffer

public TMemoryBuffer(int size)
              throws TTransportException

Create a TMemoryBuffer with an initial buffer size of size. The internal buffer will grow as necessary to accommodate the size of the data being written to it.

Parameters:

size - the initial size of the buffer

Throws:

TTransportException - on error initializing the underlying transport.

TMemoryBuffer

public TMemoryBuffer(TConfiguration config,
                     int size)
              throws TTransportException

Create a TMemoryBuffer with an initial buffer size of size. The internal buffer will grow as necessary to accommodate the size of the data being written to it.

Parameters:

config - the configuration to use.

size - the initial size of the buffer

Throws:

TTransportException - on error initializing the underlying transport.

Method Detail

isOpen
