Convert AFPOutputStream to InputStream #66

Open JesusGarciaMinas opened 2 years ago

JesusGarciaMinas commented 2 years ago

Hello,

I am making a lambda function in Java to deploy to AWS. To create the AFP file I am using the AFPOutputStream class, however, the AWS libraries only allow me to upload the file by introducing an InputStream as a parameter. Is there any way in the library to transform the AFPOuputStream object to AFPInputStream to be able to upload the object directly or is there another way to create the AFP file and make it an InputStream directly?

Thanks, Greetings.

Wrap the AFPOutputStream around a PipeOutputStream which in turn is initialized with a PipeInputStream. That’s is.

I dont understand The concept of wrapping the AfpOutputStream in the PipeOutputStream is not clear to me, could you make a code example where you can see how the PipedInputStream is wrapped and how it is subsequently initialized?

PipedStreams are a basic concept. Web search “use cases of PipedInputStream and PipedOutputStream” and you will get some answers.
