All Implemented Interfaces:

public class TypeRenamingPersistentInputStream extends com.fishlib.dataobjects.persistence.PersistentInputStream
Enterprise makes extensive use of Java serialization through WObjectOutputStream and WObjectInputStream, which use a custom encoding to write data. The consequence of this is that we'll end up with encoded type names. This class allows clients to attempt to dynamically rewrite certain type names at load time.

    Method
    Description
    protected com.fishlib.dataobjects.persistence.WObjectInputStream.ObjectConverter
    getReaderForType(String typeString)
    There are a few different paths within WObjectInputStream that resolve packages to real classes, this one handles the path when the object is plainly encoded in the stream.
    protected ObjectStreamClass
    resolveClassDescriptorOverride(ObjectStreamClass input)
     
    static UnaryOperator<String>
    setTypeRenamer(UnaryOperator<String> typeRenamer)
    Set a type renamer that returns a renamed type string or returns null if no renaming is needed.

    • setTypeRenamer

      public static UnaryOperator<String> setTypeRenamer(UnaryOperator<String> typeRenamer)
      Set a type renamer that returns a renamed type string or returns null if no renaming is needed.

      Parameters:
      typeRenamer - type renaming algorithm
      Returns:
      previous typeRenamer
      ImplNote:
      static state is used over instance state because the virtual methods that execute the type renaming are called in the super constructor, which must occur before subclass instance state is initialized.

    • getReaderForType

      protected com.fishlib.dataobjects.persistence.WObjectInputStream.ObjectConverter getReaderForType(@NotNull String typeString) throws ClassNotFoundException

      Overrides:
      getReaderForType in class com.fishlib.dataobjects.persistence.WObjectInputStream
      Parameters:
      typeString - the input type being read
      Returns:
      an WObjectInputStream.ObjectConverter
      Throws:
      ClassNotFoundException - if the conversion was not possible
