* A {@code JavaBeanLongPropertyBuilder} can be used to create
* {@link JavaBeanLongProperty JavaBeanLongProperties}. To create
* a {@code JavaBeanLongProperty} one first has to call {@link #create()}
* to generate a builder, set the required properties, and then one can
* call {@link #build()} to generate the property.
*
* Not all properties of a builder have to specified, there are several
* combinations possible. As a minimum the {@link #name(java.lang.String)} of
* the property and the {@link #bean(java.lang.Object)} have to be specified.
* If the names of the getter and setter follow the conventions, this is sufficient.
* Otherwise it is possible to specify an alternative name for the getter and setter
* ({@link #getter(java.lang.String)} and {@link #setter(java.lang.String)}) or
* the getter and setter {@code Methods} directly ({@link #getter(java.lang.reflect.Method)}
* and {@link #setter(java.lang.reflect.Method)}).
*
* All methods to change properties return a reference to this builder, to enable
* method chaining.
*
* If you have to generate adapters for the same property of several instances
* of the same class, you can reuse a {@code JavaBeanLongPropertyBuilder}
* by switching the Java Bean instance (with {@link #bean(java.lang.Object)} and
* calling {@link #build()}.
