Container Operation

Use

You use a container operation to change a container element of the workflow container at runtime.

In the workflow definition a container operation is represented with the symbol .

Features

A container operation has only one outcome and input fields for the container operation on the tab page Control.

The following operation types are available:

Arithmetic Operation

In an arithmetic operation, the result of a simple calculation is assigned to a container element of the workflow container. The arithmetic operation requires two expressions.

Assign/Append

In assigning or appending, the content of a container element or expression is assigned to a container element of the workflow container. The assignment only needs one expression. The second expression and the operator are not required.

Assign

The expression is assigned to the container element. The content of the container element is deleted first. The assignment is possible both for single-line and for multiline container elements.

When assigning to multiline container elements, the following apply:

·        <MultilineElement> =

The multiline element is initialized.

·        <MultilineElement> = <MultilineExpression>

The content of <MultilineElement> is deleted.

The content of <MultilineExpression> is assigned to <MultilineElement>.

·        <MultilineElement> = <Single-LineExpression>

The content of <MultilineElement> is deleted.

The content of <Single-LineExpression> is entered into the first line of the multiline container element.

Append

The expression is appended to the container element. This extends the content of the multiline container element. Appending is only possible for multiline container elements.

When assigning to multiline container elements, the following apply:

·        <MultilineElement> <- <MultilineExpression>

The content of <MultilineExpression> is appended to the content of <MultilineElement>.

·        <MultilineElement> <- <Single-LineExpression>

The content of <Single-LineExpression> is appended to the multiline container element as the last line.
