Method Detail

findSerializerForValue

TypedValueSerializer findSerializerForValue(org.camunda.bpm.engine.variable.value.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(org.camunda.bpm.engine.variable.value.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.
