Instance Constructors

  1. new LegacyObjectInputStream(in: ByteArrayInputStream, replacedClass: Class[_], serializedClassName: String, resolveCustomDescriptor: (ObjectStreamClass) => ObjectStreamClass)

    in

    ByteArrayInputStream of the deserialization

    replacedClass

    The class that should be the replacement

    serializedClassName

    The name of the serialized class in the input stream

    resolveCustomDescriptor

    Method to provide additional legacy class descriptor mappings for custom classes. By default, doesn't provide additional classes.

  28. def readClassDescriptor(): ObjectStreamClass

    Reads the class descriptor from the serialization stream, handling conflicting serialVersionUIDs (SUID) of old Spark NLP objects.

    Reads the class descriptor from the serialization stream, handling conflicting serialVersionUIDs (SUID) of old Spark NLP objects.

    We try to read the objects regardless of SUID (by ignoring them). In the case of reading old Maps, we need to use the serialization proxy from Scala 2.12 (removed in 2.13).

    Taken and adapted from https://stackoverflow.com/questions/795470/how-to-deserialize-an-object-persisted-in-a-db-now-when-the-object-has-different

    returns

    The class descriptor to be used for deserialization.
