Read and return an unshared object.

Returns:

an unshared object

Throws:

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

IOException - if an error occurs

doReadObject

protected abstract Object doReadObject(boolean unshared)
                                throws ClassNotFoundException,
                                       IOException

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:

ClassNotFoundException - if the class for the object could not be loaded

IOException - if an I/O error occurs

Type Parameters:

T - the object type

Parameters:

type - the object class

Returns:

the object read from the stream

Throws:
