1.3.11.36 Return Array Size

The Return Array Size processor accepts an array attribute, and returns the size of the array in a new attribute. The size of the array is the number of elements the array contains.

The output from this processor can be used in mathematical calculations and then applied to other processes for splitting the array or processing elements of the array.

The following table describes the configuration options:

Configuration	Description
Inputs	Specify a single array attribute.
Options	None.
Outputs	Describes any data attribute or flag attribute outputs.
Data Attributes	The following data attributes are output: ArraySize: a new attribute with a count of the number of elements in the array.
Flags	None.

The Return Array Size transformer presents no summary statistics on its processing.

In the Data view, the input array attribute is shown with the new array size attribute to its right.

Output Filters

None. All records input are output.
