Logger

将每个功能记录到翻译日志。将输出功能的所有属性和几何体。

Limits can be placed on both the number of features that will be logged, and the number of coordinates that will be logged per feature.

Input Ports

ClosedInput

Features to be logged.

输出端口

ClosedLogged

所有已登录Inputfeatures are output to this port unchanged.

参数

Closed日志消息

You can choose to add a message to the log file, which can be useful to identify features if you have many Logger transformers. If present, this message is output to the log file before each feature is logged.

ClosedMaximum Logged Coordinates

这number of coordinates to be logged. If not specified, the first 5 and the last 5 coordinates will be logged. If the feature has more than the maximum allowed coordinates, then only a set of coordinates at the beginning and end of the feature will be logged.

如果你输入1,所有坐标将记录;我f you enter 0, no coordinates will be logged.

If any other value is specified, only the first coordinates will be logged.

Closed最大记录功能

这maximum number of features logged for this message.

If more features than the maximum to be logged enter the transformer, the features over the limit are not logged.

Note:这Workbench parameter日期的最大功能优先于此变压器参数。

Closed日志功能类型

这日志功能类型text will set the feature type of the feature just prior to it being logged. If the log file is being saved, the logged features are also saved in a companion FFS file, and this setting is most useful to control the feature type of the features in this FFS file.

如果此参数留空，则从前面的变压器的名称和输出端口构建功能类型。当工作空间中有多个记录器或对同一记录器进行的多个连接时，这可以是有用的。例如，如果此行出现在日志中：

Feature Type: 'MyCreator_CREATED'

我t indicates that the feature was output through the CREATED port of a transformer named "MyCreator".

Usage Notes

  • An alternate way to see the attributes and geometries of features is to route them into an检查员transformer, which will display them in the FME Data Inspector.
  • 这Logged端口应用于保证在进一步处理之前记录的功能。如果Logger未输出功能，则在其他变换器完成后可能会发生日志记录。如果工作空间早期终止，甚至可能无法进行日志记录。
  • 可以通过仔细读取记录属性来区分内容的空值和字符串。空值将被记录为“”，而其内容为“”的字符串将被记录为“有值”“”。
  • 快速连接记录器变压器：右键单击一个或多个选定的读者功能类型并选择Connect Logger。

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. For more information, seeTransformer Parameter Menu Options。
