public class CompositeByteArrayRelativeReader extends Object implements IoRelativeReader
CompositeByteArray
. Using this interface has the advantage
that it can be automatically determined when a component
ByteArray
can no longer be read, and thus components can be
automatically freed. This makes it easier to use pooling for underlying
