Class ClassLoaderObjectInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.DataInput, java.io.ObjectInput, java.io.ObjectStreamConstants, java.lang.AutoCloseable
    public class ClassLoaderObjectInputStream
extends java.io.ObjectInputStream
    A special ObjectInputStream that loads a class based on a specified ClassLoader rather than the system default.

    This is useful in dynamic container environments.
