java.lang.Object com.google.common.collect.ImmutableList.Builder<E>
public static final class ImmutableList.Builder<E>
A builder for creating immutable list instances, especially public
static final
lists ("constant lists"). Example:
public static final ImmutableList<Color> GOOGLE_COLORS
= new ImmutableList.Builder<Color>()
.addAll(WEBSAFE_COLORS)
.add(new Color(0, 191, 255))
.build();
Builder instances can be reused; it is safe to call build()
multiple
times to build multiple lists in series. Each new list contains all the
elements of the ones created before it.
