clone

public static <T extends java.io.Serializable> T clone(T source)
                                                throws java.io.IOException,
                                                       java.lang.ClassNotFoundException

Clone object

类型参数:

T - the object type

参数:

source - object to be cloned

返回:

the target object of cloned

抛出:

java.io.IOException - maybe throw IOException

java.lang.ClassNotFoundException - maybe throw ClassNotFoundException

serialize

public static byte[] serialize(java.lang.Object obj)
                        throws java.io.IOException

Serialize objects into byte []

参数:

obj - object to be serialized

返回:

byte array

抛出:

java.io.IOException - maybe throw IOException

deserialize

public static <T> T deserialize(byte[] bytes)
                         throws javax.activation.UnsupportedDataTypeException

Deserialize byte [] into object

类型参数:

T - de-serialized object type

参数:

bytes - byte array

返回:

object with declare type T

抛出:

javax.activation.UnsupportedDataTypeException - if deserialize error will be throw UnsupportedDataTypeException
