OptionalDataException
public
class
OptionalDataException
extends ObjectStreamException
Exception indicating the failure of an object read operation due to
unread primitive data, or the end of data belonging to a serialized
object in the stream. This exception may be thrown in two cases:
- An attempt was made to read an object when the next element in the
stream is primitive data. In this case, the OptionalDataException's
length field is set to the number of bytes of primitive data
immediately readable from the stream, and the eof field is set to
false.
- An attempt was made to read past the end of data consumable by a
class-defined readObject or readExternal method. In this case, the
OptionalDataException's eof field is set to true, and the length field
is set to 0.
