PointonlineOverlayer.

这通过...分组parameter allows you to choose a series of attributes that must match on the features before the attributes will be merged. This can be used to ensure that the overlay occurs only on certain groups of features.

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通过...分组范围。

Parallel Processing Levels

例如,在一个四核机,paral最小lelism 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.

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

按组：此变压器将按顺序处理输入组。改变价值通过...分组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.

这重叠计数属性添加到输出线性功能包含靠近它的点特征的数量。这重叠计数属性added to output point features holds the number of linear features that the point was near to.

这点公差将值与从线路到点的距离进行比较，并且如果距离小于或等于该距离将分段线点公差价值。当发生这种匹配时，分段行的属性与该点合并，并将点的属性与线合并。

Merge Incoming: The original feature will retain all of its own un-conflicted attributes, and will additionally acquire any un-conflicted attributes that the incoming feature has. This mode will handle conflicted attributes based on theConflict Resolution范围。

Prefix Incoming：原始功能将保留其所有属性。此外，原始将获取反映传入功能属性的属性，名称为前缀Prefix范围。

Only Use Incoming: The original feature will have all of its attributes removed, except geometry attributes that start withFME_. Then, all of the attributes from one (arbitrary) incoming feature will be placed onto the original.

Use Original: If a conflict occurs, the original values will be maintained.

Use Incoming: If a conflict occurs, the values of the incoming will be transferred onto the original.

If theAccumulation Mode参数设置为Prefix Incoming, this value will prefix attributes and measures that are being added to the original feature from the incoming feature.

If the optionalList Nameis supplied, the attributes of each point used to segment an output line are added to that line's list, and the attributes of each line that a point segmented are added to that point's list.

Note:列表属性从工作台中的输出架构无法访问，除非首先使用在它们上操作的变压器处理它们，例如ListExploderorListConcatenator. All list attribute transformers are displayed in the Contents pane of the Transformer Help under清单. Alternatively,AttributeExposercan be used.
