Cloud Workflow Functions
Cloud Workflow Functions are built-in operations that execute inside the Cloud Workflow engine using the Cloud Workflow Language. They provide various helpers to address needs like retrieving the current time, generating random numbers, sorting collections and arrays, etc. Functions may operate on values and/or on reference collections and return values and/or reference collections. Arguments passed to functions are read-only. For example, the sort() function will return the result of the sort rather than modify the argument. Functions use the lower_case() notation.
