All Implemented Interfaces:

ExpressionLanguageFunction

public class DbCreateStructFunction
extends AbstractDbFunction

Provides a MEL function that creates Struct 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 struct to be created _ A array of list containing the values required to populate the struct. Values must be ordered following the order in which they are declared in type definition. 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.
