HPPC -HPPC provides template-generated implementations of typical collections, such as lists, sets and maps, for all Java primitive types. The primary driving force behind HPPC is optimization for highest performance and memory efficiency. License: Apache 2. Javolution - ibrary for real-time and ...
Collection interfaces. Represent different types of collections, such as sets, lists, and maps. These interfaces form the basis of the framework. General-purpose implementations. Primary implementations of the collection interfaces. Legacy implementations. The collection classes from earlier releases, Vector...

Determine whether the entry IDs or lists of entry IDs must be added to or removed from the index Maintaining substring indexes is relatively costly; the cost is a function of the length of the string indexed. To minimize cost, avoid unnecessary substring indexes, especially for attributes that ...
