Method Detail

main

public static void main(String[] args)

Checks class file directory hierarchies for serializable classes that do not have explicit serialVersionUID fields, and prints the names of such classes to the standard output stream. The only options are zero or more filenames that specify the roots of directory hierarchies; if no filenames are specified, the single root /vob/jive/classes is used. In those hierarchies, each file with a name ending in the suffix .class is treated as a class file; the corresponding class name is obtained from the filename by stripping off both the original prefix root filename and the .class suffix, and replacing each file separator character with a period (.). Each such class is loaded from the class loader of this tool. If the class is not an interface, directly or indirectly implements Serializable, and does not have a declared static final field named serialVersionUID, then the name of the class is printed to the standard output stream.

Parameters:

args - the roots of directory hierarchies

check

public static void check(String dir,
         int strip)

Checks the class file directory hierarchy starting from the specified directory. In the hierarchy, each file with a name ending in the suffix .class is treated as a class file; the corresponding class name is obtained from the filename by stripping off the first strip characters of prefix and the .class suffix, and replacing each file separator character with a period (.). Each such class is loaded from the class loader of this tool. If the class is not an interface, directly or indirectly implements Serializable, and does not have a declared static final field named serialVersionUID, then the name of the class is printed to the standard output stream.

Parameters:

dir - directory hierarchy root

strip - number of characters of prefix to strip from each class file name

checkClass

private static void checkClass(String file,
              int strip)

getString

private static String getString(String key)

print

private static void print(String key,
         String val)
