Attributes and Associated Operators

Overview

The attributes are used to target users. The operators are used to perform operations on user values of different attribute types.

Attribute Types and Operators

Unlaunch support following attributes type and their associated operators are listed below:

String

The String data type has some operators that are used to perform certain operations on string values. The following operators are supported in Unlaunch.

Operators Meanings
Equals, Not Equal Exact Match
Starts With, Does not Starts With Prefix String Match
Ends With, Does not Ends With Suffix String Match
Contains, Does not Contains Value match in list

Example 1: Email Ending In yahoo.com

Let’s define a rule that serves off variation to all users whose e-mail address ends with yahoo.com. First, we’ll create a new attribute of type string called email. Then we’ll use the ends with operator, and provide yahoo.com as value. Click Save Changes to save the rule.

Target Rule

Number

Number data type represents both integers and floating point numbers. When comparing numbers, the SDK will convert values you pass at the time of evaluation to the largest floating point type (e.g. Double in Java, float64 in Go) before comparison.

Operators Meanings
Equals, Not Equal Exact Match
Greater Than Numeric comparison
Greater Than or Equal Numeric comparison
Less Than Numeric comparison
Less Than or Equal Numeric comparison

Example 2: Age Greater Than 30

Let’s define a rule that serves on variation to all users whose age is greater than or equals to 30. First, we’ll create a new attribute of type number called age. Then we’ll use the Greater Than or Equals operator, and provide 30 as value. Click Save Changes to save the rule.

Target Rule Number Attribute

Boolean

For the Boolean datatype, the following operators are supported.

Operators Meanings
Equals, Not Equal Exact Match

Example 3: If User is Registered (True)

Let’s define a rule that serves on variation to all users whose registered value equals true. First, we’ll create a new attribute of type boolean called registered. Then we’ll use the Equals operator, and provide true as value. Click Save Changes to save the rule.

Target Rule Boolean Attribute

DateTime

DateTime data type represents a date and time. The following operators are supported. All date and time comparisons are done in UTC. When you provide a date and time value in the Unlaunch Console, it is assumed to be in UTC.

Operators Meanings
Equals, Not Equal Exact Match
Greater Than date comparison
Greater Than or Equal date comparison
Less Than date comparison
Less Than or Equal date comparison

Example 4: Start_Date Is today and End_Date Is After 2 Weeks

Let’s define a rule that serves on variation to all users whose start-date greater than or equals 01/12/2021 12:00:AM and end-date less than or equals 01/26/2021 12:00:AM. First, we’ll create two new attribute of type datetime called start_date and end_date. Then we’ll use the Greater Than or Equals and Less Than or Equals operator, and provide two datetime values. Click Save Changes to save the rule.

Target Rule DateTime Attribute

Date

Date data type represents a date (without time). The following operators are supported. All date comparisons are done in UTC.

Operators Meanings
Equals, Not Equal Exact Match
Greater Than date comparison
Greater Than or Equal date comparison
Less Than date comparison
Less Than or Equal date comparison

Example 5: Expiry Date Equals 01/12/2022

Let’s define a rule that serves on variation to all users whose expiry equals 01/12/2022. First, we’ll create a new attribute of type date called expiry. Then we’ll use the Equals operator, and provide 01/12/2022 as value. Click Save Changes to save the rule.

Target Rule Date Attribute

Set

A Set data type is a collection of elements. The following operators are supported. All set operators assume individual elements of the set are strings. For example, [1] == [1] but [1] != [1.0] because 1 != 1.0

Operators Meanings
Equals, Not Equal Exact Match
Is Part of, Is not Part of Subset of a set
Has Any of, Does not Have Any of Matches any set value
Has All of, Does not Have All of Matches set

Example 6: Color Set contains [red,blue,green]

Let’s define a rule that serves on variation to all users whose colors equals [red,blue,green]. First, we’ll create a new attribute of type set called colors. Then we’ll use the equals operator, and provide [red,blue,green] as value. Click Save Changes to save the rule.
