  • Method Details

    • 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.
