Append

The Append transform takes multiple inputs of either simple type or complex type. The output must be an array of either a simple type or a complex type.

The order of inputs into the transform is recognized, and is set in the Order property page.

The Cardinality property page on the transform specifies which indexes the transform should process. The first index element is 1.

The Append transform provides a nested transform for each input in the output array.

The nested transforms are performed for each input sequentially, producing occurrences of the output array. For example, first over all elements in the first input, then over all elements in the second input.

Inputs of single, non-repeating elements are also allowed; each single input element adds an extra occurrence to the output array.

The output array size is the total of the input elements, minus any elements that are filtered out from the Append Cardinality property page, or through some filtering in the nested transforms.
