Methods

Modifier and Type	Method and Description
static void	deserialize(SerializationStreamReader streamReader, EnumMap instance)
void	deserializeInstance(SerializationStreamReader streamReader, EnumMap instance) Deserializes the content of the object from the SerializationStreamReader.
boolean	hasCustomInstantiateInstance()
static EnumMap	instantiate(SerializationStreamReader streamReader) EnumMap has no empty constructor; you must provide the class literal to the constructor.
EnumMap	instantiateInstance(SerializationStreamReader streamReader) Instantiates an object from the SerializationStreamReader.
static void	serialize(SerializationStreamWriter streamWriter, EnumMap instance) Since this code is only run in hosted mode, reflection can be used.

Method Detail

deserialize

public static void deserialize(SerializationStreamReader streamReader,
               EnumMap instance)
                        throws SerializationException

Throws:

SerializationException

instantiate

public static EnumMap instantiate(SerializationStreamReader streamReader)
                           throws SerializationException

EnumMap has no empty constructor; you must provide the class literal to the constructor. However GWT doesn't emulate java.lang.Class.forName() nor is java.util.Class GWT-RPC serializable. In order to get the type across the wire, one enum of the appropriate class is serialized at the beginning of the stream. Upon deserialization this enum's type is introspected and used in the constructor for the new EnumMap.

Throws:

SerializationException

serialize

public static void serialize(SerializationStreamWriter streamWriter,
             EnumMap instance)
                      throws SerializationException

Since this code is only run in hosted mode, reflection can be used.

Throws:

SerializationException

deserializeInstance

public void deserializeInstance(SerializationStreamReader streamReader,
                       EnumMap instance)
                         throws SerializationException

Description copied from class: CustomFieldSerializer

Deserializes the content of the object from the SerializationStreamReader.

Specified by:

deserializeInstance in class CustomFieldSerializer<EnumMap>

Parameters:

streamReader - the SerializationStreamReader to read the object's content from

instance - the object instance to deserialize

Throws:

SerializationException - if the deserialization operation is not successful

hasCustomInstantiateInstance

public boolean hasCustomInstantiateInstance()

Overrides:

hasCustomInstantiateInstance in class CustomFieldSerializer<EnumMap>

Returns:

true if a specialist CustomFieldSerializer.instantiateInstance(com.google.gwt.user.client.rpc.SerializationStreamReader) is implemented; false otherwise

instantiateInstance

public EnumMap instantiateInstance(SerializationStreamReader streamReader)
                            throws SerializationException

Description copied from class: CustomFieldSerializer

Instantiates an object from the SerializationStreamReader.

Most of the time, this can be left unimplemented and the framework will instantiate the instance itself. This is typically used when the object being deserialized is immutable, hence it has to be created with its state already set.

If this is overridden, the CustomFieldSerializer.hasCustomInstantiateInstance() method must return true in order for the framework to know to call it.

Overrides:

instantiateInstance in class CustomFieldSerializer<EnumMap>

Parameters:

streamReader - the SerializationStreamReader to read the object's content from

Returns:

an object that has been loaded from the SerializationStreamReader

Throws:

SerializationException - if the instantiation operation is not successful

serializeInstance

public void serializeInstance(SerializationStreamWriter streamWriter,
                     EnumMap instance)
                       throws SerializationException

Description copied from class: CustomFieldSerializer

Serializes the content of the object into the SerializationStreamWriter.

Specified by:

serializeInstance in class CustomFieldSerializer<EnumMap>

Parameters:

streamWriter - the SerializationStreamWriter to write the object's content to

instance - the object instance to serialize

Throws:

SerializationException - if the serialization operation is not successful
