Data types

Throughout the documentation we refer to data types that can be used in the expression parser and its functions and field codes.

Data types define what kind of data a function needs as input and what you should expect as output.

Data types in JWT

Data type

Description

text

This type represents any kind of text or character string including all kinds of select and multi-select fields

number

This type represents numeric values, and is also used to store date, time and date-time values. Learn more about Dates, times and time zones

If you need the output as text, simply add % in front of the field code or directly insert the field code as text.

list


  • Number list: This type represents a collection of numeric values returned by various functions. The size may vary from 0 to any number of numeric values.

  • Text list: This type represents a collection of text values returned by various functions. The size may vary from 0 to any number of text values.

  • Issue list: This type represents a collection of issues. The size may vary from 0 to any number of issues. It is returned by issue selection of filtering functions.

Lists

If you need to "flatten" the list, or simply convert it to a text, to be written into any field, comment, etc., make sure to have a look at the 

toString()

function!

Boolean

Some operators, workflow functions, parser functions, and automation elements return a logical, or boolean, value of true or false.These examples include, but are not limited to:


Converting (casting) data types

Converting (or casting) data types is very important throughout all functions provided by JWT.

To be able to set, transform or calculate values it might be necessary to turn a text value to a number, a number or a timestamp to a text, and even individual text or number values to a list.

The following functions will help you to achieve that.

Available functions

Function Short description Output
issueKeysToIssueList()

Converts a text containing issue keys into an issue list.

ISSUE LIST
toInteger()

Converts text into an integer.

NUMBER
toNumber()

Converts text into a number.

NUMBER
toNumberList()

Converts text containing numbers into a number list.

NUMBER LIST
toString()

Converts numbers and lists into plain text.

TEXT
toStringList()

Converts text into a text list.

TEXT LIST

Whenever you write a numeric term at the right-hand side of the + operator or a comparison operator like = , and the left-hand side is occupied by a text term, JWT will automatically transform the right-hand side term into a text toString().

Operator

Example

+

"His age is " + 30 is equivalent to "His age is " + toString(30)

= (any comparison operator)

"30" = 30 is equivalent to "30" = toString(30)
