This class should only be needed for low-level codecs like collections and probably shouldn't * be used in normal application code. * *
Instances of this class are discovered automatically by {@link CodecScanner} and used for * custom registration of a codec. This can be useful when a single codec is used for multiple * classes or when the class that is being serialized has a hidden type, e.g., {@link * com.google.common.collect.RegularImmutableList}. * *
If a {@link CodecRegisterer} definition exists, the codec will only be registered by the * {@link CodecRegisterer#register} method. Otherwise, an attempt will be made to register the codec * to its generic parameter type. * *
Implementations must have a default constructor. * *
Inheriting {@link CodecRegisterer} through a superclass is illegal. It must be directly * implemented. Also, the generic parameter of {@link CodecRegisterer} must be reified. * *
Constraint violations will cause exceptions to be raised from {@link CodecScanner}.
