PointonpointOvertLayer.

在通过...分组parameter specifies a series of attributes that must match on the point and polygon 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: see关于并行处理有关详细信息。

此参数确定变压器是否应跨行进程执行工作。如果启用了，将为每个组的组启动一个过程通过...分组参数。

并行处理水平

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: This transformer will process input groups in order. Changes on the value of the通过...分组输入流上的参数将触发当前累计组上的批处理。如果组很大/复杂，则会提高整体速度，但如果输入组未真正订购，则可能导致不期望的行为。

在重叠计数属性added to output point features holds the number of point features to which the point was near.

每个输入点都有来自任何其他点的属性Point Tolerancedistance merged onto it.

Merge Incoming：原始功能将保留其所有未冲突的属性，并且另外会获取传入功能具有的任何未冲突的属性。此模式将根据此模式处理冲突属性解决冲突参数。

前缀传入：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，名称为前缀字首参数。

只使用收入：原始功能将删除其所有属性，除了从中开始的几何属性FME_。在n, all of the attributes from one (arbitrary) incoming feature will be placed onto the original.

使用原件: If a conflict occurs, the original values will be maintained.

Use Incoming：如果发生冲突，则传入的值将转移到原始内。

如果是Accumulation Mode参数设置为前缀传入, this value will prefix attributes that are being added to the original feature from the incoming feature.

如果是可选的List Name提供，每个输出点还将具有包含来自内部的每个点的属性列表Point Tolerancedistance.

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ListExploderorListConcateator。所有列表属性转换器都显示在变压器帮助的内容窗格中清单。或者，AttributeExposer可以使用。
