Supported list types

This function filters a number list by the list elements' cardinality (how often they appear in the list) using the given comparison.

filterByCardinality(numberList, operator, number) #Output: Number list

Parser expression

Description

filterByCardinality([anyNumberList], >, 1)

In this example a number list with those elements would be returned, that occurred more than once in the number list.

filterByCardinality([1, 1, 2, 3, 4, 4, 4, 5], >, 1)

This example returns

[1, 4]

since 1 and 4 are occurring more than once in the list.

filterByCardinality([1, 1, 2, 3, 4, 4, 4, 5], =, 1)

This example returns

[2, 3, 5]

since these values are occurring exactly once in the list.

Parameters used in this function

Parameter	Input (data type)	Description
`numberList`		Any given number list.
`operator`		One of the following comparison operators: =, !=, <, <=, > and >=.
`number`		Any given number that will be used in combination with the operator to filter the given list.

This function returns a .

If the number list is empty or the comparison won't be fullfilled by any element, the function returns an empty .

A variant for text lists.

filterByCardinality(textList, operator, number) #Output: Text list

Parser expression

Description

filterByCardinality(["tiger", "tiger", "tiger", "lion", "lion", "cat", "lynx"], <, 3)

This example returns

["lion", "cat", "lynx"]

since these elements are occurring less than 3 times in the list.

filterByCardinality(fieldValue(%{issue.component}, subtasks()), =, count(subtasks()))

This example returns a text list with those Components who are present in all sub-tasks.

To achieve this, the following functions are used:

Parameters used in this function

Parameter	Input (data type)	Description
`textList`		Any given text list.
`operator`		One of the following comparison operators: =, !=, <, <=, > and >=.
`number`		Any given number that will be used in combination with the operator to filter the given list.

This function returns a .

If the number list is empty or the comparison won't be fullfilled by any element, the function returns an empty .

A variant for issue lists.

filterByCardinality(issueList, operator, number) #Output: Issue list

Parser expression

Description

filterByCardinality(linkedIssues(), >, 1)

This example returns an issue list with all issues that are linked to the current issue more than once.

To achieve this, the following functions are used:

Parameters used in this function

Parameter	Input (data type)	Description
`issueList`		Any given issue list. Usually this value is retrieved from a function (e.g. linkedIssues() or subtasks()).
operator		One of the following comparison operators: =, !=, <, <=, > and >=.
`number`		Any given number that will be used in combination with the operator to filter the given list.

This function returns an .

If the number list is empty or the comparison won't be fullfilled by any element, the function returns an empty .

Short description	Filters a given number, text, or issue list by the number of occurence of elements.
