is

Select is to evaluate the relationship between two sides of a conditional statement. Either side can typically be the content returned by a resource attribute, value, or arithmetic expression. If the resource attribute is of the data type List (array, vector, or enumeration), the available evaluations become includes and includes any of. Otherwise, the choices are:

includes

includes any of

is between

is between but not equal to

is empty

is greater than

is greater than or equal to

is included in

is less than or equal to

is less than

is not empty

is not

Is Empty/Is Not Empty

The evaluations is empty and is not empty allow a rule to check for the existence of a null value or an empty list. When using either of these evaluations, the right side of the evaluation is unnecessary and is removed.

Left side of Evaluation	Evaluation	Result
Resource Attribute (non-list type)	is empty	true if attribute is null, otherwise false
Resource Attribute (non-list type)	is not empty	false if attribute is null, otherwise true
Resource Attribute (list type)	is empty	true if list is empty, otherwise false
Resource Attribute (list type)	is not empty	false if list is empty, otherwise true
Request Attributes or Session Attributes (non-list type)	is empty	false if attribute/parameter exists and value is not null; true if attribute/parameter does not exist or value is null
Request Attributes or Session Attributes (non-list type)	is not empty	true if attribute/parameter exists and value is not null; false if attribute/parameter does not exist or value is null
Request Attributes or Session Attributes (list type)	is empty	true if attribute/parameter does not exist or list is empty; false if attribute/parameter exists and list has data
Request Attributes or Session Attributes (list type)	is not empty	false if attribute/parameter does not exist or list is empty; true if attribute/parameter exists and list has data

Profiler evaluations

If you choose to evaluate a profiler instead of a resource attribute in the Specify a Resource Attribute window, the available evaluations are:

is all of

is any of

is not

is not any of

On the right side of the evaluation, the possible choices are the profiles that are defined within that profiler. You may select one or more profiles for the right side of the evaluation.
