方法详细资料

clone

public static java.lang.Object clone(java.io.Serializable object)

Deep clone an Object using serialization.

This is many times slower than writing clone methods by hand on all objects in your object graph. However, for complex object graphs, or for those that don't support deep cloning this can be a simple alternative implementation. Of course all the objects must be Serializable.

参数:

object - the Serializable object to clone

返回:

the cloned object

serialize

public static void serialize(java.io.Serializable obj,
             java.io.OutputStream outputStream)

Serializes an Object to the specified stream.

The stream will be closed once the object is written. This avoids the need for a finally clause, and maybe also exception handling, in the application code.

The stream passed in is not buffered internally within this method. This is the responsibility of your application if desired.

参数:

obj - the object to serialize to bytes, may be null

outputStream - the stream to write to, must not be null

抛出:

java.lang.IllegalArgumentException - if outputStream is null

serialize

public static byte[] serialize(java.io.Serializable obj)

Serializes an Object to a byte array for storage/serialization.

参数:

obj - the object to serialize to bytes

返回:

a byte[] with the converted Serializable

deserialize

public static java.lang.Object deserialize(java.io.InputStream inputStream)

Deserializes an Object from the specified stream.

The stream will be closed once the object is written. This avoids the need for a finally clause, and maybe also exception handling, in the application code.

The stream passed in is not buffered internally within this method. This is the responsibility of your application if desired.

参数:

inputStream - the serialized object input stream, must not be null

返回:

the deserialized object

抛出:

java.lang.IllegalArgumentException - if inputStream is null

deserialize

public static java.lang.Object deserialize(byte[] objectData)

Deserializes a single Object from an array of bytes.

参数:

objectData - the serialized object, must not be null

返回:

the deserialized object

抛出:

java.lang.IllegalArgumentException - if objectData is null

deserializable

public static java.lang.Object deserializable(java.io.File cacheFile)
                                       throws java.io.IOException,
                                              java.lang.ClassNotFoundException

抛出:

java.io.IOException

java.lang.ClassNotFoundException

serializable

public static void serializable(java.io.Serializable obj,
                java.io.File cacheFile)
                         throws java.io.IOException

抛出:

java.io.IOException
