-/**
- * {@code SingleFieldBuilder} implements a structure that a protocol
- * message uses to hold a single field of another protocol message. It supports
- * the classical use case of setting an immutable {@link Message} as the value
- * of the field and is highly optimized around this.
- * <br>
- * It also supports the additional use case of setting a {@link Message.Builder}
- * as the field and deferring conversion of that {@code Builder}
- * to an immutable {@code Message}. In this way, it's possible to maintain
- * a tree of {@code Builder}'s that acts as a fully read/write data
- * structure.
- * <br>
- * Logically, one can think of a tree of builders as converting the entire tree
- * to messages when build is called on the root or when any method is called
- * that desires a Message instead of a Builder. In terms of the implementation,
- * the {@code SingleFieldBuilder} and {@code RepeatedFieldBuilder}
- * classes cache messages that were created so that messages only need to be
- * created when some change occured in its builder or a builder for one of its
- * descendants.
- *
- * @param <MType> the type of message for the field
- * @param <BType> the type of builder for the field
- * @param <IType> the common interface for the message and the builder
- *
