 * Represents one component for a GuardedInvocation of a potentially multi-namespace operation of an
 * {@link AbstractJavaLinker}. In addition to holding a guarded invocation, it holds semantic information about its
 * guard. All guards produced in the AbstractJavaLinker are either "Class.isInstance()" or "getClass() == clazz"
 * expressions. This allows choosing the most restrictive guard as the guard for the composition of two components.
