Class ByteImmutableList

  • All Implemented Interfaces:
    ByteCollection, ByteIterable, ByteList, ByteStack, Stack<java.lang.Byte>, java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<java.util.List<? extends java.lang.Byte>>, java.lang.Iterable<java.lang.Byte>, java.util.Collection<java.lang.Byte>, java.util.List<java.lang.Byte>, java.util.RandomAccess

    public class ByteImmutableList
    extends AbstractByteList
    implements ByteList, java.util.RandomAccess, java.lang.Cloneable, java.io.Serializable
    A type-specific array-based immutable list; provides some additional methods that use polymorphism to avoid (un)boxing.

    Instances of this class are immutable and (contrarily to mutable array-based list implementations) the backing array is not exposed. Instances can be built using a variety of methods, but note that constructors using an array will not make a defensive copy.

    This class implements the bulk method getElements() using high-performance system calls (e.g., System.arraycopy()) instead of expensive loops.

        Description copied from interface: ByteList
        Sorts this list using a sort not assured to be stable.

        Pass null to sort using natural ordering.

        This differs from List.sort(java.util.Comparator) in that the results are not assured to be stable, but may be a bit faster.

        Unless a subclass specifies otherwise, the results of the method if the list is concurrently modified during the sort are unspecified.
