Method Summary

VariableSerializers	addSerializer(TypedValueSerializer<?> serializer)
VariableSerializers	addSerializer(TypedValueSerializer<?> serializer, int index) Add type at the given index.
TypedValueSerializer	findSerializerForValue(TypedValue value) Selects the TypedValueSerializer which should be used for persisting a VariableValue.
TypedValueSerializer<?>	getSerializerByName(String serializerName)
int	getSerializerIndex(TypedValueSerializer<?> serializer)
int	getSerializerIndexByName(String serializerName)
VariableSerializers	removeSerializer(TypedValueSerializer<?> serializer)

Method Detail

findSerializerForValue

TypedValueSerializer findSerializerForValue(TypedValue value)

Selects the TypedValueSerializer which should be used for persisting a VariableValue.

Parameters:

value - the value to persist

Returns:

the VariableValueserializer selected for persisting the value or 'null' in case no serializer can be found

getSerializerByName

TypedValueSerializer<?> getSerializerByName(String serializerName)

Returns:

the serializer for the given serializerName name. Returns null if no type was found with the name.

addSerializer

VariableSerializers addSerializer(TypedValueSerializer<?> serializer)

addSerializer

VariableSerializers addSerializer(TypedValueSerializer<?> serializer,
                                  int index)

Add type at the given index. The index is used when finding a serializer for a VariableValue. When different serializers can store a specific variable value, the one with the smallest index will be used.

removeSerializer

VariableSerializers removeSerializer(TypedValueSerializer<?> serializer)

getSerializerIndex

int getSerializerIndex(TypedValueSerializer<?> serializer)

getSerializerIndexByName

int getSerializerIndexByName(String serializerName)
