+/**
+ * A factory for creating method handles for linking missing member behavior
+ * in {@link BeansLinker}. BeansLinker links these method handles into guarded
+ * invocations for link requests specifying {@code GET_*} and {@code SET_*}
+ * {@link StandardOperation}s when it is either certain or possible that the
+ * requested member (property, method, or element) is missing. They will be
+ * linked both for {@link NamedOperation named} and unnamed operations. The
+ * implementer must ensure that the parameter types of the returned method
+ * handle match the parameter types of the call site described in the link
+ * request. The return types can differ, though, to allow
+ * {@link DynamicLinkerFactory#setPrelinkTransformer(jdk.dynalink.linker.GuardedInvocationTransformer)}
+ * late return type transformations}. It is allowed to return {@code null} for a
+ * method handle if the default behavior is sufficient.
+ * <h2>Default missing member behavior</h2>
+ * When a {@link BeansLinker} is configured without a missing member handler
+ * factory, or the factory returns {@code null} for a particular handler
+ * creation invocation, the default behavior is used. The default behavior is to
+ * return {@code null} from
+ * {@link BeansLinker#getGuardedInvocation(LinkRequest, LinkerServices)} when it
+ * can be determined at link time that the linked operation will never address
+ * an existing member. This lets the {@code DynamicLinker} attempt the next
+ * linker if there is one, or ultimately fail the link request with
+ * {@link NoSuchDynamicMethodException}. For other cases (typically all unnamed
+ * member operations as well as most named operations on collection elements)
+ * {@code BeansLinker} will produce a conditional linkage that will return
+ * {@code null} when invoked at runtime with a name that does not match any
+ * member for getters and silently ignore the passed values for setters.
+ * <h2>Implementing exception-throwing behavior</h2>
+ * Note that if the language-specific behavior for an operation on a missing
+ * member is to throw an exception then the factory should produce a method
+ * handle that throws the exception when invoked, and must not throw an
+ * exception itself, as the linkage for the missing member is often conditional.
+ *
+ * @see BeansLinker#BeansLinker(MissingMemberHandlerFactory)
