描述
eliminate_runseliminate_runsEliminateRunsEliminateRunsEliminateRunseliminate_runs eliminates all runs of the
run length encoding of the input regions which are shorter
than ElimShorterElimShorterElimShorterElimShorterelimShorterelim_shorter or longer as
ElimLongerElimLongerElimLongerElimLongerelimLongerelim_longer。
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
eliminate_runseliminate_runsEliminateRunsEliminateRunsEliminateRunseliminate_runs 在所有参数正确时返回 2 ( H_MSG_TRUE )。当输入为空（未指定区域）时则可设置行为通过 set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>) 以及输入区域为空时可设置行为通过 set_system('empty_region_result',<Result>)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)set_system("empty_region_result",<Result>)。如有必要，则抛出异常。
