名称
pruningpruningPruningPruningpruning — 修剪一个区域的分枝。
签名
描述
pruningpruningPruningPruningPruningpruning removes branches from a skeleton
(RegionRegionRegionRegionregionregion) having a length less than LengthLengthLengthLengthlengthlength.
All other branches are preserved.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 在元组级别上自动并行化。

结果
pruningpruningPruningPruningPruningpruning 在所有参数正确时返回 2 ( H_MSG_TRUE )。当输入区域为空或不存在时，其行为可通过以下方式设置：
-
无区域：
set_system('no_object_result',<RegionResult>)set_system("no_object_result",<RegionResult>)SetSystem("no_object_result",<RegionResult>)SetSystem("no_object_result",<RegionResult>)SetSystem("no_object_result",<RegionResult>)set_system("no_object_result",<RegionResult>)
-
空区域：
set_system('empty_region_result',<RegionResult>)set_system("empty_region_result",<RegionResult>)SetSystem("empty_region_result",<RegionResult>)SetSystem("empty_region_result",<RegionResult>)SetSystem("empty_region_result",<RegionResult>)set_system("empty_region_result",<RegionResult>)
否则，将抛出异常。
