public class DbCreateArrayFunction
extends AbstractDbFunction

Provides a MEL function that creates Array instances.

Function receives three arguments: _ Name of the DB config that will be used to create the value _ Name of the type corresponding to the array to be created _ A array of list containing the values required to populate the array In order to work, this function requires an active transaction on the provided DB config. This requirement is forced so created values are used inside the same connection and to avoid leaked connections.
