Following the JTS technical specs [5], this manual will make a distinction between constructive (buffer, convex hull) and set-theoretic operations (intersection, union, etc.). The individual operations will be fully described in a following section of the manual.

按照JTS的技术规范，本手册将对构造性操作（缓冲区、凸壳）和集合论操作（相交、联合等）进行区分。各项操作将在本手册的下一节中全面描述。
