MRF2D部门间

计算所有输入要素之间的交点，在交点处打断圆弧和直线。模糊交叉点也可以从一个公差距离内的几何图形创建，但实际上不接触或交叉。

Output Ports

ClosedCleaned

通过Cleanedport will have a new attribute "mrf_clean_status" added to specify whether the feature was modified, created, or unchanged in the cleaning process. The possible values of this attribute are "Modified", "Created" and "Original".

ClosedFlagged

如果“交点动作”设置为在交点处分割线，则输入线将在真实交点处分割为单独的输出线。如果设置为标记交点，则将通过Flagged端口为点、标签或圆，具体取决于所选的标志类型。

Parameters

Transformer

Closed分组依据

If selected, each group of features with the same values in the分组依据attributes will be processed separately from other groups.

ClosedParallel Processing

Note:How parallel processing works with FME: seeAbout Parallel Processingfor detailed information.

This parameter determines whether or not the transformer should perform the work across parallel processes. If it is enabled, a process will be launched for each group specified by the分组依据parameter.

Parallel Processing Levels

Parameter Number of Processes
No Parallelism 1
最小 coresThe processor, or CPU, is the physical part of the computer that performs mathematical calculations. It is the most important part of a computer system. Traditional processors have only one core on the processor, meaning that at any given time, only one set of calculations is being performed. If a processor is dual-core, this means the single chip contains hardware for two processors, now called cores to distinguish them from the single chip, running simultaneously, side by side.

中等 exact number of cores
咄咄逼人的 cores x 1.5
Extreme 芯x 2

For example, on a quad-core machine, minimal parallelism will result in two simultaneous FME processes. Extreme parallelism on an 8-core machine would result in 16 simultaneous processes.

You can experiment with this feature and view the information in the Windows Task Manager and the Workbench Log window.

ClosedInput Ordered

No: This is the default behavior. Processing will only occur in this transformer once all input is present.

By Group: This transformer will process input groups in order. Changes on the value of the分组依据parameter on the input stream will trigger batch processing on the currently accumulating group. This will improve overall speed if groups are large/complex, but could cause undesired behavior if input groups are not truly ordered.

Parameters

Closed清洁公差

除非指定了特征公差属性且该属性有效，否则清洁公差将用作默认公差。允许的最小公差为0.0。

Closed特征公差属性

用于清除数据的层数由输入特征的不同公差值的数量决定。具有相同公差的特征将被处理为位于同一图层上。

ClosedIntersection Action

If set to Split Lines at Intersections, intersections are computed between all input features, breaking arcs and lines wherever an intersection occurs. If set to Flag Intersections, the Flag Type and Flag Size parameters are enabled.

ClosedCompute Fuzzy Intersections

If set to Yes, a fuzzy intersection is also created from geometries which are within one of the tolerance distances, but do not actually touch or cross.

ClosedFlag Type and Flag Size

This parameter sets the flag type for true intersection points as a point, label or circle, if Intersection Action is set to Flag Intersections.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, clickbeside the applicable parameter.
