Grid Column Configuration Operators
Grid Configuration Operators allow you to add special columns to your grid which are somehow assembled or converted using operators listed below.

its operation on their values. For example, the
ObjectFieldGetter has the
manufacturer data attribute as
child and calls
getName on the value of the
manufacturer attribute (which is a manufacturer
data object). This results in a column that contains the manufacturer name.
With some operators this basic concept gets extended or reversed, please see detailed descriptions in their docs.
In addition to that, there are also operators who work without any data attribute as
child. One example for that is the
By default, the string representation of the result value is displayed.
This can be changed wrapping the result into a renderer operator.
In the following example, the image (the result of
getImage_1()) would be rendered as image.
