Synopsis

serialver [ options ] [ classnames ]

options

The command-line options. See Options.

classnames

The classes for which the serialVersionUID is to be returned.

Description

The serialver command returns the serialVersionUID for one or more classes in a form suitable for copying into an evolving class. When called with no arguments, the serialver command prints a usage line.

Options

-classpath path-files

Sets the search path for application classes and resources. Separate classes and resources with a colon (:).

-show

Displays a simple user interface. Enter the full class name and press either the Enter key or the Show button to display the serialVersionUID.

-Joption

Passes option to the Java Virtual Machine, where option is one of the options described on the reference page for the Java application launcher. For example, -J-Xms48m sets the startup memory to 48 MB. See java(1).

Notes

The serialver command loads and initializes the specified classes in its virtual machine, and by default, it does not set a security manager. If the serialver command is to be run with untrusted classes, then a security manager can be set with the following option:

-J-Djava.security.manager

When necessary, a security policy can be specified with the following option:

-J-Djava.security.policy=<policy file>
