Class SerializableUtil

java.lang.Object

edu.ucla.sspace.util.SerializableUtil

public class SerializableUtil
extends Object

A utility class for loading and saving typed Serializable objects from files, streams and readers. This class encapsulates all the common serializing code and type casting to allow a clean interface for classes that need to interact with serialized objects. All checked IOException cases are rethrown as IOError.

Method Detail

save

public static void save(Object o,
        String file)

Serializes the object to the provided file.

Parameters:

o - the object to be stored in the file

file - the file in which the object should be stored

save

public static void save(Object o,
        File file)

Serializes the object to the provided file.

Parameters:

o - the object to be stored in the file

file - the file in which the object should be stored

save

public static void save(Object o,
        OutputStream stream)

Serializes the object to the provided stream. This method does not close the stream after writing.

Parameters:

o - the object to be stored in the file

stream - the stream in which the object should be stored

save

public static byte[] save(Object o)

Serializes the object to a byte array.

Parameters:

o - the object to be stored in the file

load

public static <T> T load(File file,
         Class<T> type)

Loads a serialized object of the specifed type from the file.

Parameters:

file - the file from which a mapping should be loaded

type - the type of the object being deserialized

Returns:

the object that was serialized in the file

load

public static <T> T load(String fileName)

Loads a serialized object of the specifed type from the file.

Parameters:

fileName - the file name from which an object should be loaded

Returns:

the object that was serialized in the file

load

public static <T> T load(File file)

Loads a serialized object of the specifed type from the file.

Parameters:

file - the file from which a mapping should be loaded

Returns:

the object that was serialized in the file

load

public static <T> T load(InputStream stream)

Loads a serialized object of the specifed type from the stream. This method does not close the stream after reading

Parameters:

file - the file from which a mapping should be loaded

type - the type of the object being deserialized

Returns:

the object that was serialized in the file
