Friendly Enough Expression Language

Friendly Enough Expression Language, or FEEL, is a new standard promoted by the OMG. The DCR Process Engine has implemented a subset of the FEEL langage as it’s expression language.

FEEL lists

The DCR Process Engine 4.8.0 introduces support for FEEL lists.

An example FEEL list of the numbers 1, 2 and 3 is written in this way:

[1, 2, 3]

In a similar manner a FEEL list of strings can be written as:

["Hello", "World"]

list contains(<list>, <value>) –> true | false

count(<list>) –> integer value with the number of elements in the list

append(<list>,<element>) –> returns a new list where the element is appended to the list

concatenate(<list1>,<list2>) –> returns a new list where the two lists are concatenated
