Lib version is the "version" of the SWC format. Major number changes represent big (although not by definition incompatble) changes, such as bytecode format revs. Minor number changes are intended to represent easy-to-support modifications. The only universal rule is that the compiler will warn when a "future" major version is found in a SWC that's being read in. It's expected that incompatible changes will arise. Ad-hoc guard code will be added to implement those dividing lines. The way the code is currently laid out, these would probably be implemented in Swc.read(), but in any case they should be finable by looking at the callers of VersionInfo.getLibVersion().

Version 1.2: Add <keep-as3-metadata> container to catalog.xml to perserve metadata Version 1.1: Add <digest> container to catalog xml for cross-domain rsls support. Add "signatureChecksum" attribute to "script" element. Version 1.0: Initial version.

IsNewerLibVersion

public static boolean IsNewerLibVersion(String swcLibVersion,
                        boolean compareMajorVersion)

Parameters:

swcLibVersion - - library version to compare with the current library version.

compareMajorVersion - - if true, compare only the major versions. Otherwise compare both major and minor versions.

Returns:

true if the given library version is greater than the compiled in library version.

compareVersions

public static int compareVersions(String version1,
                  String version2,
                  boolean compareMajorVersion)

Compare two version strings that are in at "Major.minor" format. Examples) "1.0", "1.1"

Parameters:

version1 - first version

version2 - second version

compareMajorVersion - compare only the major versions, disregarding the minor version.

Returns:

zero if the versions are equal less than zero if version1 is less than version2 greater than zero if version1 is greater than version2
