The extension to regular RTSJ that jRate currently provides or that will provide soon are the following:
jRate provides a non-standard memory area called CTMemory, which trades allocation time with memory recycling time. This memory uses a zeroed buffer to achieve constant time allocation regardless of the size, but then when the memory area needs to be cleaned up, the used part is zeroed all at once.
Status: Currently Available
jRate provides a generative memory area framework which uses C++ template meta-programming and allows the generation of several different types of memory areas. Moreover its policy-based implementation makes it extremely easy to add new policies and thus extend the generative power of the framework. For more information on the design of this generative framework read the MemoryArea framework design document.
