Returns:

true, if another object can be deserialized from the stream, otherwise false.

Throws:

DeserializationException

next

<T> T next()

Deserializes an object from the stream.

Type Parameters:

T - the expected type of the object

Returns:

the deserialized object.

Parameters:

closeReader - if true, the underlying reader will be closed, too.

Throws:
