java.lang.Objectjava.io.InputStream

com.tangosol.io.AbstractByteArrayReadBuffer.ByteArrayBufferInput
public class AbstractByteArrayReadBuffer.ByteArrayBufferInput
This is a simple implementation of the BufferInput interface on top of a byte array.
This implementation extends InputStream, but only so that it can be passed to anything that takes an InputStream.
