LIST

LIST:
  itemType: { itemType } # required
  items: # required
    - { value1 }
    - { value2 }
    # ...

Description​

The LIST operation creates a constant, ordered List of values. This operation allows you to define a static, ordered list of Text or Bytes strings directly within your logic. It preserves the order of elements and allows for duplicates.

Parameters​

  • itemType (Text | Bytes, required):

    • Specifies the type of items in the list. Valid values are TEXT or BYTES.

  • items (list of strings, required):

    • A YAML list of strings that will form the list.
    • Unlike a SET, empty strings and duplicate values are preserved in the list.

Return Type​

List

Examples​

  1. Creating a list with duplicate Text items:

    LIST:
      itemType: TEXT
      items:
        - "a"
        - "b"
        - "a"

    This returns a list containing ["a", "b", "a"].

  2. Creating a list that includes empty strings:

    LIST:
      itemType: TEXT
      items:
        - "a"
        - ""
        - "b"

    This returns a list containing ["a", "", "b"].
