      public class SerialInput
      extends ClassResolver.Stream

  A specialized `ObjectInputStream` that gets class description information from a `ClassCatalog`. It is used by `SerialBinding`.

  This class is used instead of an `ObjectInputStream`, which it extends, to read an object stream written by the `SerialOutput` class. For reading objects from a database normally one of the serial binding classes is used. `SerialInput` is used when an `ObjectInputStream` is needed along with compact storage. A `ClassCatalog` must be supplied, however, to stored shared class descriptions.

    - #### SerialInput

          public SerialInput​(java.io.InputStream in,
                             ClassCatalog classCatalog)
                      throws java.io.IOException

      Creates a serial input stream.
      Parameters:
        `in` - is the input stream from which compact serialized objects will be read.
        `classCatalog` - is the catalog containing the class descriptions for the serialized objects.
      Throws:
        `java.io.IOException` - if an I/O error occurs while reading stream header.

    - #### SerialInput

          public SerialInput​(java.io.InputStream in,
                             ClassCatalog classCatalog,
                             java.lang.ClassLoader classLoader)
                      throws java.io.IOException

      Creates a serial input stream.
      Parameters:
        `in` - is the input stream from which compact serialized objects will be read.
        `classCatalog` - is the catalog containing the class descriptions for the serialized objects.
        `classLoader` - is the class loader to use, or null if a default class loader should be used.
      Throws:
        `java.io.IOException` - if an I/O error occurs while reading stream header.
