列表历史语法

计算在列表中找到的值的直方图，并在功能的新列表属性中返回这些值。

Parameters

使用说明

If the source list did not have elements, a new list will not be created and this transformer will have made no changes to the feature.

Example

If a feature with this list enters this transformer:

somelist{0}.val = 'apple'

somelist{1}.val='甜甜圈'

somelist{2}.val = 'aardvark'

somelist{3}.val='苹果'

somelist{4}.val = 'aardvark'

somelist{5}.val='苹果'

the resulting feature will have this list attribute:

_histogram{0}.value = 'apple'

_直方图{0}.count=3

_直方图{1}.值='aardvark'

_histogram{1}.count = 2

_直方图{2}.value='甜甜圈'

_直方图{2}.count=1

编辑变压器参数

使用一组菜单选项，可以通过引用工作空间中的其他元素来指定转换器参数。更高级的功能，如高级编辑器和算术编辑器，也可以在一些变压器。要访问这些选项的菜单，请单击beside the applicable parameter. For more information, see变压器参数菜单选项.
