      java.io.InputStream
          java.io.ObjectInputStream
              org.apache.commons.io.input.ClassLoaderObjectInputStream

All Implemented Interfaces:
  Closeable, DataInput, ObjectInput, ObjectStreamConstants

    public class ClassLoaderObjectInputStream

extends 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.

### ClassLoaderObjectInputStream

    public ClassLoaderObjectInputStream(ClassLoader classLoader,
                                        InputStream inputStream)
                                 throws IOException,
                                        StreamCorruptedException

  Constructs a new ClassLoaderObjectInputStream.

  Parameters:
    `classLoader` - the ClassLoader from which classes should be loaded
    `inputStream` - the InputStream to work on
  Throws:
    `IOException` - in case of an I/O error
    `StreamCorruptedException` - if the stream is corrupted

Method Detail

### resolveClass

    protected Class<?> resolveClass(ObjectStreamClass objectStreamClass)
                             throws IOException,
                                    ClassNotFoundException

  Resolve a class specified by the descriptor using the specified ClassLoader or the super ClassLoader.

  Overrides:
    `resolveClass` in class `ObjectInputStream`
  Parameters:
    `objectStreamClass` - descriptor of the class
  Returns:
    the Class object described by the ObjectStreamClass
  Throws:
    `IOException` - in case of an I/O error
    `ClassNotFoundException` - if the Class cannot be found
