描述

算子 get_region_runsget_region_runsGetRegionRunsGetRegionRunsGetRegionRunsget_region_runs returns the region data in the form of chord tuples. The chord representation is caused by examining a region line by line with ascending line number (= from “top” to “bottom”). Every line is passed from left to right (ascending column number); storing all starting and ending points of region segments (= chords). Thus a region can be described by a sequence of chords, a chord being defined by line number, starting and ending points (column number). The operator get_region_runsget_region_runsGetRegionRunsGetRegionRunsGetRegionRunsget_region_runs returns the three components of the chords in the form of tuples. In case of an empty region three empty tuples are returned.

注意

Only one region may be passed.

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）。
• 未采用并行化处理。

参数

结果

算子 get_region_runsget_region_runsGetRegionRunsGetRegionRunsGetRegionRunsget_region_runs normally returns the value 2 ( H_MSG_TRUE )。 If more than one region is passed an exception is raised. 当输入为空（无可用输入区域）时，可设置行为通过算子 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>)。
