Method Detail

serialize

public void serialize(Object o,
                      File f)
               throws FileNotFoundException,
                      IOException

Serialize an Object to a file on the hard drive. Each object to be serialized has to implement the Serializable interface.

Parameters:

o - the Object

f - the location

Throws:

FileNotFoundException - if the file cannot be located

IOException - if the file cannot be read or written

deserialize

public Object deserialize(File f)
                   throws FileNotFoundException,
                          IOException,
                          ClassNotFoundException

Deserialize an object from a given binary file. Each object to be deserialized has to implement the Serializable interface.

Parameters:

f - the file on the hard drive

Returns:

the Object

Throws:

FileNotFoundException - if the file cannot be located

IOException - if the file cannot be read or written

ClassNotFoundException - if the object cannot be restored into a class on the class path

getBytes

public static byte[] getBytes(Object o)

Serializes an Object into a byte[]. Each object to be serialized has to implement the Serializable interface.

Parameters:

o - the object to be serialized

Returns:

the byte representation

getObject

public static Object getObject(byte[] data)

Deserializes an byte[] to an Object. Each object to be deserialized has to implement the Serializable interface.

Parameters:

data - the byte array

Returns:

the restored object
