kandi X-RAY | jillegal Summary

jillegal is a Java library. jillegal has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub.
jillegal is a library including unknown tricks of java. it abstracts developer from low-level details to implement those tricks. its design and logic are based on java 8 and jrockit so it can be used at only java 8 and jrockit platforms. java 6 and java 7 supports are in progress and as soon as possible they will be released. demo applications are avaiable at [https://github.com/serkan-ozal/jillegal-demo](https://github.com/serkan-ozal/jillegal-demo) and [https://github.com/serkan-ozal/jillegal-demo-web](https://github.com/serkan-ozal/jillegal-demo-web). note: this is an experimental project. so, please notify me for all kind of suggestions, feedbacks and issues (with crash log files and test cases if possible :)). currently it has three main modules: offheap, instrumentation and in memory compiler. instrumenting and redefining any java class, interface, …​ (even core java classes) at runtime with developer friendly api (with builder pattern based design) is supported. you can add your custom pre/post listeners to method and constructor invocations dynamically. it serves a platform to develop your custom aop framework. it uses java instrumentation api but adding extra vm argument (like -javaagent:<jarpath>[=<options>]) is not required. jillegal has its own internal agent and it can enable it’s agent at runtime dynamically. 1.3. in memory compiler module. to make any of your class, just annotate it with

                      What is Jillegal?

                      Design and logic of Jillegal OffHeap module different from all of the other offheap frameworks. It doesn't serilalize/deserialize objects to/from allocated offheap memory region. Because objects already lives on offheap and GC doesn't track them :). With this feature, all objects in pool are exist as sequential at memory, so sequential accessing to them is faster. Because, they will be fetched to CPU cache together as limited size of CPU cache.
                      
                      &lt;a name="LIMITATIONS"&gt;&lt;/a&gt;
                      [LIMITATIONS: ](#LIMITATIONS)
                      * Only **Hotspot Java 8 JVM**, **Oracle JRockit JVM** and **Azul's Zulu Java 8 JVM** are supported. **Java 6** and **Java 7** based JVMs are not supported yet.
                      
                      * Only **CMS** collector (`-XX:+UseConcMarkSweepGC`), **G1** collector (`-XX:+UseG1GC`) and **Serial** collector (`-XX:+UseSerialGC`) are supported for Hotspot JVM. Don't try with other collectors such as **Default** or **Parallel** collector (`-XX:+UseParallelGC` or `-XX:+UseParallelOldGC`) since there is an issue associated with these collectors's Young GC collections :).
                      
                      * Offheap module needs to disabled compressed-oops (`-XX:-UseCompressedOops`) since there is no quarantee that allocated native memory space can be represented with compressed-oops with huge memory sizes.
                      
                      * **Off-Heap** objects **must not** reference to **On-Heap** objects since they can be moved while GC and **Off-Heap** objects are not aware of this movement since they are not under GC control. However, **On-Heap** objects can reference to **Off-Heap** objects and also **Off-Heap** objects can references to **Off-Heap** objects as well.
