count(set)

Tinderbox Icon


Operator Type:   Set maths
Operator Scope of Action:   Set

A function count() counts the number of discrete items in the specified attribute (of set data type).

count(attribute)

The attribute argument is evaluated so can use, $attribute(note) or more complex expressions to get data - as long as the result is an attribute of the Set data type.

For example if KeyAttributes for the current note is "Color;Color2;NameFont" then the code

count($KeyAttributes) 

is effectively

count(Color;Color2;NameFont) 

and not surprisingly returns 3. Note that the count is not all unique values for the attribute across the whole TBX - scope is restricted to 'this' note or another nominated note. Specimen usage:

count($KeyAttributes) 

count($KeyAttributes(some other note))
