Method Details

findSerializerForValue

TypedValueSerializer findSerializerForValue(TypedValue value,
 VariableSerializerFactory fallBackSerializerFactory)

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

Parameters:

value - the value to persist

fallBackSerializerFactory - a factory to build a fallback serializer in case no suiting serializer can be determined. If this factory is not able to build serializer either, an exception is thrown. May be null

Returns:

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

findSerializerForValue

TypedValueSerializer findSerializerForValue(TypedValue value)

Same as calling findSerializerForValue(TypedValue, VariableSerializerFactory) with no fallback serializer factory.

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)

join

VariableSerializers join(VariableSerializers other)

Merges two VariableSerializers instances into one. Implementations may apply different merging strategies.

getSerializers

List<TypedValueSerializer<?>> getSerializers()

Returns the serializers as a list in the order of their indices.
