Method Detail

writeObject

public static byte[] writeObject(Object object)
                          throws IOException

Serialize an Object to a ByteArray

Returns:

a byte[] array

Throws:

IOException

readObject

public static Object readObject(byte[] data)
                         throws IOException,
                                ClassNotFoundException

Read an Object from a byte array

Returns:

answer

Throws:

IOException

ClassNotFoundException

readObject

public static Object readObject(InputStream in)
                         throws IOException,
                                ClassNotFoundException

read an object from an InputStream

Returns:

result

Throws:

IOException

ClassNotFoundException

objectFromByteBuffer

public static Object objectFromByteBuffer(byte[] buffer)
                                   throws Exception

Creates an object from a byte buffer.

Throws:

Exception

objectToByteBuffer

public static byte[] objectToByteBuffer(Object obj)
                                 throws Exception

Serializes an object into a byte buffer. The object has to implement interface Serializable or Externalizable.

Throws:

Exception

deepClone

public static Object deepClone(Object obj)

A deep copy makes a distinct copy of each of the object's fields, recursing through the entire graph of other objects referenced by the object being copied. Deep clone by serialize and deserialize the object and return the deserialized version. A deep copy/clone, assuming everything in the tree is serializable. NOTE: This method is very expensive!, don't use this method if you need performance.

Parameters:

obj - the object to clone, the object and object context must implement java.io.Serializable.

Returns:

the copied object include all object references.

Throws:

IllegalArgumentException - Failed to perform deep clone. The object of the context object is not implements java.io.Serializable.

writeObject

public static void writeObject(OutputStream out,
                               Object obj)
                        throws IOException

Write an Object to an OutputStream

Throws:

IOException
