Class LibraryUpdate

java.lang.Object

org.safs.install.LibraryUpdate

public class LibraryUpdate
extends java.lang.Object

A generic customizable File directory updater for SAFS users wishing to update certain library assets with newer assets that might be available on the network in a central location.

For example, users can use this to grab centrally located build assets to update the SAFS\lib JAR files. Or, it can be used to update TCAFS libraries located in TCAFS\TCAFS\Script.

The support for this is narrowly focused to SAFS assets at this time.

Specifically, only the following file types are supported:

• .DAT
• .SVB
• .JAR
• .EXE

In addition, only source assets dated newer than Aug 01, 2012 are considered for update.

The class supports backing up older files into any specified directory. It also supports directory recursion, and an option to override the prompting for file replacement.

There are no SAFS dependencies in this class and can be packaged stand-alone in an executable JAR file.

Command-line options:

-q	(quiet mode, no prompt dialog), it should be put before other argument if present"
"-prompt:titlebar"	(alternate prompt title bar message) This parameter should appear before other parameters (at this time)
-b:backupdir	**(backup dir for replaced files)
-s:sourcedir	* (source dir containing newer files, or an HTTP URL to a ZIP) Supports HTTP URL to a ZIP file that would be downloaded and extracted into a temporary directory to be used as the sourcedir for the update. Note: Any spaces in the URL should be retained as spaces--not URLEncoded. The code will handle URL encoding of spaces. Ex: -s:http://sourceforge.net/projects/safsdev/files/SAFS Updates/SAFS.LIB Updates/SAFS.LIB.UPDATE.LATEST.ZIP
-t:targetdir	* (target dir receiving newer files)
-f	(force w/o prompting for each file)
-r	(recurse into sub-directories)
-a	(file of all types will be copy, default false)"
-nob	(no file backups required)
	* - required parameter.
	** - only required if -nob not provided.

Entry points are:

• Instance: processArgs
• Static: main
