Is there a concise way to create an InputSupplier for an InputStream in Google Guava?

Question

There are a few factory methods in Google Guava to create InputSuppliers, e.g. from a byte[]:

ByteStreams.newInputStreamSupplier(bytes);
         


        

Answer 1

No, I haven't seen anything.
I think you have found the best way.
The only alternative where to store the inputstream in a byte array or a file and create a Supplier with ByteStreams.newInputStreamSupplier() or Files.newInputStreamSupplier(), but I would discourage to do like that.
You could also use

public static long copy(InputStream from, OutputStream to)

from

ByteStreams
