Editing Transformer Parameters

使用一组菜单选项，可以通过引用工作区中的其他元素来分配变压器参数。一些变压器也可提供更高级的功能，例如高级编辑器和算术编辑器。要访问这些选项的菜单，请单击beside the applicable parameter. For more information, seeTransformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Using the Text Editor

The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

Text Editor

Using the Arithmetic Editor

The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.

算术编辑器

Conditional Values

Set values depending on one or more test conditions that either pass or fail.

Parameter Condition Definition Dialog

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

设置值 - 无论是否直接在参数中输入或使用其中一个编辑器和包含字符串的表达式都是构造的，都会评估这些函数的字符串和表达式。因此，这些函数的名称（以@ <function_name.>) should not be used as literal string values.

String Functions

 These functions manipulate and format strings.

Special Characters

 A set of control characters is available in the Text Editor.

Math Functions

 Math functions are available in both editors.
Date/Time Functions Date and time functions are available in the Text Editor.

Math Operators

 These operators are available in the Arithmetic Editor.

FME Feature Functions

 These return primarily feature-specific values.

FME Parameters

 FME and workspace-specific parameters may be used.
Creating and Modifying User Parameters Create your own editable parameters.

Dialog Options - Tables

具有桌面参数的变压器具有填充和操作值的其他工具。

Row Reordering

Enabled once you have clicked on a row item. Choices include:

  • Add a row
  • Remove a row
  • Move current row up one
  • Move current row down one
  • Move current row to top
  • Move current row to bottom

Cut, Copy, and Paste

Enabled once you have clicked on a row item. Choices include:

  • Cut a row - delete and copy to clipboard
  • Copy a row to the clipboard
  • 从剪贴板粘贴一排

Cut, copy, and paste may be used within a transformer, or between transformers.

过滤

 Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output.

Import

 Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.

Reset/Refresh

Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers.

Note:Not all tools are available in all transformers.
