Read and return an unshared object.

Returns:

an unshared object

Throws:

java.lang.ClassNotFoundException - if the class of a serialized object cannot be found

Implementation of the actual object-reading method.

Parameters:

unshared - true if the instance should be unshared, false if it is shared

Returns:

the object to read

Throws:

java.lang.ClassNotFoundException - if the class for the object could not be loaded
