> FSDataInputStreamWrapper unbuffer can NOT invoke the classes that NOT implements CanUnbuffer
but its parents class implements CanUnbuffer
> For example:
> There are 1 interface I1 and one class implements I1 named PC1 and the class C1 extends
from PC1
> If we want to invoke the C1 unbuffer() method the FSDataInputStreamWrapper unbuffer 
can NOT do that.
