Method Details

getBytes

public static byte[] getBytes(Object obj)

Serialize an object to a byte array

getByteCount

public static long getByteCount(Object obj)
                         throws IOException

Returns the size of a serializable object. Non-serializable objects will throw an IOException.

It is important to note that the returned value is length of the byte stream after the object has been serialized. The returned value does not represent the amount of memory the object uses. There is no accurate way to determine the size of an object in memory.

Parameters:

obj -

Returns:

the number of bytes in the serialized object

Throws:

IOException

getObject

public static Object getObject(byte[] bytes)

Deserialize a byte array back to an object; if there is an error, it is logged, and null is returned.

getObjectException

public static Object getObjectException(byte[] bytes)
                                 throws ClassCastException,
ClassNotFoundException,
IOException

Deserializes a byte array back to an object.

Parameters:

bytes - the array of bytes

Returns:

the deserialized object.

Throws:

ClassNotFoundException - when the class can not be deserialized.

IOException - when a general Input/Output error happen.

ClassCastException

doHashCode

public static int doHashCode(Object o1)

getObjectFromFactory

public static <A,
R> R getObjectFromFactory(Class<? extends Factory<R,A>> factoryInterface,
 A obj)
                                    throws ClassNotFoundException

Throws:

ClassNotFoundException
