Description

Intermediate class for handling field expression function objects (e.g. blendingFactor etc.) whereinto a single field is input.

The class is not an executable function object itself, yet a provider for common entries to its derived function objects.

Usage

The optional-inherited entries provided by fieldExpression to the derived function objects are as follows:

<userDefinedSubDictName1>
{
    // Mandatory and other optional entries
    ...

    // Optional (inherited) entries (runtime modifiable)
    field             <field>;
    result            <fieldResult>;
}

where the entries mean:

Property	Description	Type	Required	Default
field	Name of the operand field	word	yes	-
result	Name of the output field	wordList	no	<FO>(<f1>,...)
