/**
 * A value layout. A value layout is used to model the memory layout associated with values of basic data types, such as <em>integral</em> types
 * (either signed or unsigned) and <em>floating-point</em> types. Each value layout has a size and a byte order (see {@link ByteOrder}).
 *
 * <p>
 * This is a <a href="{@docRoot}/java.base/java/lang/doc-files/ValueBased.html">value-based</a>
 * class; programmers should treat instances that are
 * {@linkplain #equals(Object) equal} as interchangeable and should not
 * use instances for synchronization, or unpredictable behavior may
 * occur. For example, in a future release, synchronization may fail.
 * The {@code equals} method should be used for comparisons.
 *
 * <p> Unless otherwise specified, passing a {@code null} argument, or an array argument containing one or more {@code null}
 * elements to a method in this class causes a {@link NullPointerException NullPointerException} to be thrown. </p>
 *
 * @implSpec
 * This class is immutable and thread-safe.
