This method replicates the logic of SmallRyeConfig.getValues(String, Class, IntFunction) for the given default value string.

Type Parameters:

T - the item type

C - the collection type

Parameters:

config - the config instance (must not be null)

defaultValue - the default value string (must not be null)

itemType - the item type class (must not be null)

converterClass - - The converter class to use

collectionFactory - the collection factory (must not be null)

Returns:

the collection (not null)

getValue
