IS_EMPTY

IS_EMPTY:
  arg: { arg } # required

Description​

The IS_EMPTY operation checks if the provided argument arg is considered empty. What constitutes "empty" depends on the provided type (see Type System). This operation returns a Boolean value: true if the argument is empty, and false otherwise.

Parameters​

  • arg (Operation<Any>, required):
    • Specifies the value to be checked for emptiness.
    • This can be any operation that resolves to a supported Compliance Engine type (Text, Bytes, Number, DateTime, Collection, etc.).

Return Type​

Boolean

Examples​

  1. Checking if a text field is empty:

    IS_EMPTY:
      arg:
        FIELD:
          path: CA10__notes__c

    This example checks if the value of the CA10__notes__c field is empty (null, empty text, or text containing only spaces).

  2. Checking if a collection is empty:

    IS_EMPTY:
      arg:
        SET_FROM:
          arg:
            FIELD:
              path: CA10__availabilityZones__c
          separator: ","

    This example checks if the collection created from the comma-separated string in CA10__availabilityZones__c field is empty. The result of true will be produces for following values of CA10__availabilityZones__c: null, "", " ", " , ". See Set type for more details.

  3. Using IS_EMPTY in a condition:

    - status: INCOMPLIANT
      currentStateMessage: "Description is missing"
      remediationMessage: "Please provide a description for this resource."
      check:
        IS_EMPTY:
          arg:
            FIELD:
              path: CA10__description__c

    This condition will be met if the CA10__description__c field is empty, setting the status to INCOMPLIANT.
