Backend modules compat
compat (Meaning compatibility) stems from the previous iteration in oVirt’s life. oVirt (Then Solid Ice) was originally written in C#. Following Redhat’s 2008 purchase of Qumranet, the engine was re-written in Java. The compatibility module fills in the gaps of Java, as the re-write originally targeted Java 5 which lacked several features then existing in C#. The compat module is essentially a collection of utility classes that exist in C# and do not in Java.
- Event and EventArgs
Deprecation: Many of these classes have been deprecated since the re-write, and recommended classes are to be used instead. StringHelper, for example, is to be avoided and org.apache.commons.lang.StringUtils used instead.
