Method Details

serializeObject

public static byte[] serializeObject(Serializable o)
                              throws Exception

Serializes an Object so it can be sent over the cluster.

Parameters:

o - Object to serialize.

Returns:

byte[] representing serialized object.

Throws:

Exception

serializeAndGZipObject

public static byte[] serializeAndGZipObject(Serializable o)
                                     throws Exception

Throws:

Exception

deserializeObject

public static Object deserializeObject(GatewayContext context,
 byte[] b)
                                throws Exception

Deserializes an object that was serialized by serializeObject(). Requires the gateway context so it can resolve classes provided by modules.

Parameters:

b - byte[] to deserialize.

Returns:

Object representing the deserialized byte[].

Throws:

Exception

deserializeObject

public static Object deserializeObject(GatewayContext context,
 byte[] b,
 Map<String,String> aliasClassPaths)
                                throws Exception

Deserializes an object using some specified alias class(es). Should be used if object has a class path that has since been changed.

Throws:

Exception

unzipAndDeserializeObject

public static Object unzipAndDeserializeObject(GatewayContext context,
 byte[] b)
                                        throws Exception

Throws:

Exception

 byte[] b,
 Map<String,String> aliasClassPaths)
                                        throws Exception

Throws:
