Name
ObjectStreamConstants
Synopsis
This interface defines various
constants used by the Java
object-serialization mechanism. Two important constants are
PROTOCOL_VERSION_1 and
PROTOCOL_VERSION_2, which specify the version of
the serialization protocol to use. In Java 1.2, you
can pass either of these values to the
useProtocolVersion(
) method of an ObjectOutputStream. By
default, Java 1.2 uses Version 2 of the protocol, and Java 1.1 uses
Version 1 when serializing objects. Java 1.2 can deserialize objects
written using either version of the protocol, as can Java 1.1.7 and
later. If you want to serialize an object so that it can be read by
versions of Java prior to Java 1.1.7, use
PROTOCOL_VERSION_1.
The other constants defined by this interface are low-level values used by the serialization protocol. You do not need to use them unless you are reimplementing the serialization mechanism yourself.
