Method Details

source

Iterable<A> source()

Returns the source from which this list is populated.

Returns:

the source from which this list is populated

force

List<A> force()

Populates this list completely, and returns an efficient view.

If this list is already populated completely, nothing happens.

Returns:

an unmodifiable view on this list with efficient access

See Also:

• isComplete()

isComplete

boolean isComplete()

Checks whether this list has been completely populated.

A positive result can be due to a preceding call to force(), due to iterating the list exhaustively, or due to a whole-list operation such as List.size().

Returns:

true if this list is completely populated; false if there are elements left to draw from the source on demand
