Class FactoryOnlyAttribute

Namespace

Dec

Assembly

dec.dll

Marks a Converter class as factory-only: it will not be auto-registered by Dec's converter scan, and must be produced on demand by a Config.ConverterFactory callback instead.

FactoryOnlyAttribute

Remarks

Without this attribute, Dec's scan would treat the class as a normal Converter, try to instantiate it via its parameterless constructor, and register it against the type declared in its Converter base. For factory-only converters the parameterless-constructor requirement is usually unsatisfiable, and even when it isn't, the declared-type registration would shadow the Config.ConverterFactory lookup that's supposed to produce the right instance.

ConverterStringDynamic, ConverterRecordDynamic, and ConverterFactoryDynamic already carry this attribute themselves, so every Dynamic subclass inherits it automatically and doesn't need to be tagged.
