Conditions

Conditions are the checks that determine whether a rule passes or fails. They can be combined using logical operators.

Single Condition

The simplest rule has one condition:

A **Person** is adult
  if __age__ of **Person** is greater than or equal to 18.

AND Conditions

Use and to require all conditions to be true:

A **Person** qualifies
  if __age__ of **Person** is greater than or equal to 18
  and __income__ of **Person** is greater than 50000
  and __credit_score__ of **Person** is greater than 700.

All three conditions must pass for the rule to pass.

OR Conditions

Use or to require at least one condition to be true:

A **User** gets discount
  if __age__ of **User** is greater than or equal to 65
  or __is_student__ of **User** is equal to true
  or __is_veteran__ of **User** is equal to true.

Policy Rule

A **User** gets discount if __age__ of **User** is greater than or equal to 65 or __is_student__ of **User** is equal to true or __is_veteran__ of **User** is equal to true.

Test Data (JSON)

{ "User": { "age": 22, "is_student": true, "is_veteran": false } }

Mixed AND/OR

You can mix and and or in a single rule:

A **Person** is eligible
  if __age__ of **Person** is greater than 18
  and __status__ of **Person** is equal to "active"
  or __role__ of **Person** is equal to "admin".

Optional Conditions: -and / -or

The -and and -or operators work as alternative condition connectors. They provide a way to express optional or bracketed conditions:

A **Person** qualifies
  if __age__ of **Person** is greater than 18
  -and __status__ of **Person** is equal to "active".

The -and operator functions like and but signals an optional grouping. The -or operator functions similarly for disjunctions.
