Method Detail

writeClass

public static void writeClass(ObjectOutputStream out,

                       throws IOException

Deprecated.

Serializes the class reference so readClass(ObjectInputStream) can deserialize it. Supports null class references.

Parameters:

out - The ObjectOutputStream to serialize to.

cls - A class or null.

Throws:

IOException - Rethrows any IOExceptions from the ObjectOutputStream

writeClassArray

public static void writeClassArray(ObjectOutputStream out,
                                   Class<?>[] classes)
                            throws IOException

Deprecated.

Serializes the class references so readClassArray(ObjectInputStream) can deserialize it. Supports null class arrays.

Parameters:

out - The ObjectOutputStream to serialize to.

classes - An array containing class references or null.

Throws:

IOException - Rethrows any IOExceptions from the ObjectOutputStream

readClassArray

public static Class<?>[] readClassArray(ObjectInputStream in)
                                 throws ClassNotFoundException,
                                        IOException

Deprecated.

Deserializes a class references serialized by writeClassArray(ObjectOutputStream, Class[]). Supports null class arrays.

Parameters:

in - ObjectInputStream to read from.

Returns:

Class array with the class references or null.

Throws:

ClassNotFoundException - If one of the classes could not be resolved.

IOException - Rethrows IOExceptions from the ObjectInputStream

resolveClass

public static Class<?> resolveClass(String className)
                             throws ClassNotFoundException

Deprecated.

readClass

public static Class<?> readClass(ObjectInputStream in)
                          throws IOException,
                                 ClassNotFoundException

Deprecated.

Deserializes a class reference serialized by writeClass(ObjectOutputStream, Class). Supports null class references.

Parameters:

in - ObjectInputStream to read from.

Returns:

Class reference to the resolved class

Throws:

ClassNotFoundException - If the class could not be resolved.

IOException - Rethrows IOExceptions from the ObjectInputStream
