Class MD5HashFileGenerator

java.lang.Object

com.github.mati1979.play.soyplugin.ajax.hash.MD5HashFileGenerator

All Implemented Interfaces:

HashFileGenerator

public class MD5HashFileGenerator
extends java.lang.Object
implements HashFileGenerator

Created with IntelliJ IDEA. User: mszczap Date: 29.06.13 Time: 23:58 An MD5 algorithm implementation of a hash file generator It is important to notice that this implementation supports a dev and prod modes in dev (hotReloadMode) mode the implementation will not cache md5 hash checksums, conversely in prod mode it will cache it. The cache can be fine tuned via setters.
