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

ByteStreams.newInputStreamSupplier(bytes);

Or from a File:

Files.newInputStreamSupplier(file);

Is there a similar way to to create an InputSupplier for a given InputStream?

That is, a way that's more concise than an anonymous class:

new InputSupplier<InputStream>() {
    public InputStream getInput() throws IOException {
        return inputStream;
    }
};

Background: I'd like to use InputStreams with e.g. Files.copy(...) or ByteStreams.equal(...).
