Valve to write an item property to a file.

Valve operates on the Current Item Set and will be executed on every item.

Configuration property content_type determines if the source value is a decoded binary and if content_type is text (matches content type: 'text/*'), value is treated as plain text, otherwise value is assumed binary and base64 decoded before written to file.

File will be written using the charset specified in the charset parameter in content_type. If charset isn’t specified, the default charset will be used.

Valve operates on the Current Item Set and will process all items surviving the common item filtering rules.
