Koloboke - Java Collections till the last breadcrumb of memory and performance

  •        0

Koloboke aims to replace the standard Java collections and streams with more efficient implementations. The current version of Koloboke focuses on replacing java.util.HashSet and java.util.HashMap. It provides a complete set of primitive type implementations for each collection. Its able to avoid the expensive boxing/unboxing of primitives and saves memory for boxed primitive objects. It is the fastest and the most memory efficient library implementing hash maps and sets.
