public class DefaultDataBufferFactory
Default implementation of the DataBufferFactory interface. Allows for
specification of the default initial capacity at construction time, as well
as whether heap-based or direct buffers are to be preferred.
Return a new DataBuffer composed of the dataBuffers elements joined together.
Depending on the implementation, the returned buffer may be a single buffer containing all
data of the provided buffers, or it may be a true composite that contains references to the

This implementation creates a single DefaultDataBuffer to contain the data
