getName

public String getName()

Description copied from interface: TypedValueSerializer

The name of this serializer. The name is used when persisting the ValueFields populated by this serializer.

Returns:

the name of this serializer.

canWriteValue

protected boolean canWriteValue(TypedValue value)

Specified by:

canWriteValue in class AbstractTypedValueSerializer<ObjectValue>

isDeserializedObjectValue

protected boolean isDeserializedObjectValue(TypedValue value)

convertToTypedValue

public ObjectValue convertToTypedValue(UntypedValueImpl untypedValue)

Description copied from interface: TypedValueSerializer

Returns a typed value for the provided untyped value. This is used on cases where the user sets an untyped value which is then detected to be handled by this TypedValueSerializer (by invocation of TypedValueSerializer.canHandle(TypedValue)).

Parameters:

untypedValue - the untyped value

Returns:

the corresponding typed value

writeValue

public void writeValue(ObjectValue objectValue,
                       ValueFields valueFields)

Description copied from interface: TypedValueSerializer

Serialize a TypedValue to the ValueFields.

Parameters:

objectValue - the TypedValue to persist

valueFields - the ValueFields to which the value should be persisted

readValue

public ObjectValue readValue(ValueFields valueFields,
                             boolean deserializeObjectValue,
                             boolean asTransientValue)

Description copied from interface: TypedValueSerializer

Retrieve a TypedValue from the provided ValueFields.

Parameters:

valueFields - the ValueFields to retrieve the value from

deserializeObjectValue - indicates whether a SerializableValue should be deserialized.

Returns:

the TypedValue
