Convert the given iterator to a sorted list.

Type Parameters:

SRCTYPE - The type of elements to iterate (source).

DSTTYPE - The type of elements to return (destination).

Parameters:

it - Input iterator. May not be null.

aConverter - The converter to be used. May not be null.

Returns:

a non-null ArrayList based on the results of CollectionHelper.getSortedInline(List).

Convert the given iterator to a sorted list.

Type Parameters:

SRCTYPE - The type of elements to iterate (source).

DSTTYPE - The type of elements to return (destination).

Parameters:

it - Input iterator. May not be null.

aConverter - The converter to be used. May not be null.

aComparator - The comparator to use. May not be null.

Returns:

a non-null ArrayList based on the results of CollectionHelper.getSortedInline(List, Comparator).
