Woobaben Some thoughts in my mind Talk is cheap, show me the code. ArrayBackedHashMap (using Linear Probing) - originally inspired by Mikhail Vorontsov's ObjObjMap, implemented java.util.Map interface --Done ArrayBackedHashSet - Array Backed Hash Set --Done Faster java object attribute accessors by utlilising sun.misc.Unsafe --Done Faster java heap object copy (clone) by sun.misc.Unsafe --Done Data Reader heap/off-heap --Done Near plan Custom UTF8 String - InProgress MethodHandle Java Field access, OGNL support Heap object serialiser and deserialiser (JSON/binary format) String search / replace library Template engine Off-heap object facility Off-heap object copy/serialise/deserialise Future plan Integration of Kilim (Java coroutine - lightweight thread) JNI - use 'javacritical' optimisation with off-heap memory And some other more...
