Method Detail

serializeObject

public static byte[] serializeObject(java.io.Serializable o)
                              throws java.lang.Exception

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

Parameters:

o - Object to serialize.

Returns:

byte[] representing serialized object.

Throws:

java.lang.Exception

serializeAndGZipObject

public static byte[] serializeAndGZipObject(java.io.Serializable o)
                                     throws java.lang.Exception

Throws:

java.lang.Exception

deserializeObject

public static java.lang.Object deserializeObject(GatewayContext context,
                                                 byte[] b)
                                          throws java.lang.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:

java.lang.Exception

deserializeObject

public static java.lang.Object deserializeObject(GatewayContext context,
                                                 byte[] b,
                                                 java.util.Map<java.lang.String,java.lang.String> aliasClassPaths)
                                          throws java.lang.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:

java.lang.Exception

unzipAndDeserializeObject

public static java.lang.Object unzipAndDeserializeObject(GatewayContext context,
                                                         byte[] b)
