Sort by attribute

CLEM.Groupings.FilterByAttribute

Identifies a single attribute of the individuals with which to sort the current selected individuals

A Sort by attribute component allows you to sort the selected individuals from a list based on an attribute of the individual identified by name.

See Filtering and sorting individuals for details on using multiple sorts in a Filter group.

The following parameters are used to define this activity

Each attribute added to an individual is identified by a tag (or label) and may also contain an associated value. This property identifies the attribute for sorting.

As attributes are added to individuals by activities an individual may or may not have a particular attribute. This style will use the boolean check of whether the attribute exists on each individual.

You can perform filtering on the value (floating point number) associated with the attribute identified by the tag set above. If the activity does not exist an empty value (0) is returned.

The sort can either arrange individuals by the value of the property in Ascending or Descending order.

As True and False equate to 1 and 0 respectively, a ascending sort based on whether the attribute exists will put all individuals without the specified attribute (false = 0) first.

This value is applied to individuals in the list to be sorted when they do not contain the specified attribute. This allows you to determine where these individuals should occur in the sorted list.

When an attribute is missing from an individual in the list, this value will be used to determine its position in the sorted list.
