Method Summary

Modifier and TypeMethod and Description
pack-priv static <
the List's element type
E> List<E>

Returns:

the new list
listCopy(Collection<? extends E>
the input collection
coll)

Copies a collection into a new List, unless the arg is already a safe, null-prohibiting unmodifiable list, in which case the arg itself is returned.

pack-priv static <
the List's element type
E> List<E>

Returns:

the new list
listFromArray(E...
the input array
input)

Creates a new List from an untrusted array, creating a new array for internal storage, and checking for and rejecting null elements.

pack-priv static <
the List's element type
E> List<E>

Returns:

the new list
listFromTrustedArray(Object...
the input array
input)

Creates a new List from a trusted array, checking for and rejecting null elements.

pack-priv static <
the List's element type
E> List<E>

Returns:

the new list
listFromTrustedArrayNullsAllowed(Object...
the input array
input)

Creates a new List from a trusted array, allowing null elements.
