Hello,
As you have noted, you should be able to use the reference service to
give you the correct object back using eg,
referenceService.renderIdentifier(reference, byte[].class, null)
(where byte[].class can be replaced with whatever you want). However
the problem here is you need a StreamToValueConverterSPI to do the
conversion from a stream to the type you want and there isn't one for
Base64.
So, an alternative is to try using the local worker
EncodeByteArrayToBase64 which takes a byte array as input and outputs
a Base64 object. Or write your own StreamToValueConverterSPI :)
Hope this helps.
Cheers,
Ian

Hi,
I have a question regarding the renderIdentifier function of the
ReferenceService.
The content of a reference can be accessed via the renderIdentifier,
and
I guess the most common type might be StringReference or
InlineByteArrayReference. As I can cast a StringReference to a
String by
using String.class, how can I achieve this with
InlineByteArrayReference?
Most of my outputs will either be a more or less formatted String
output
(e.g. flat files) or images. As these images are transferred as Base64
encoded Strings wrapped inside an InlineByteArrayReference, how do I
extract this Base64 encoded String properly as String.class won't work
(I get somewhat like "binary as plain text").
Any help would be appreciated.
Regards,
Michael
