[Solved] Py implementation of Java ByteArrayXInputStream...

[_savage]

I'm trying to follow this example, but I haven't quite figured out how to use a byte[] as an input stream in Python. In Java there seems to exist an adapter called ByteArrayToXInputStreamAdapter. Does an equivalent exist for the Python implementation?

UNO module c.s.s.io provides XInputStream and XOutputStream

Thanks, I saw those. But being interface declarations I still would have to come up with a class that implements these interfaces. What I was asking in my original question was if there is already a Python equivalent for this Java implementation ByteArrayXInputStreamAdapter. Might that even be part of the shipping UNO blob?

This is beyond my knowledge.

Sometimes com.sun.star.io.SequenceInputStream service can be used to this task.

hanya: funny you say that! I just stumbled upon this code which uses the SequenceInputStream service And based on that example, here's something that works for me:

Code: Select all

# Read the content of a file as byte[]
def _file2bytes(fname):                                                     
    with open(fname, "rb") as f:                                            
        return f.read()                                                     

# Create an XInputStream implementation from a byte[]
def _file2istream(fname):                                                   
    fbytes = _file2bytes(fname)                                             
    istream = context.ServiceManager.createInstanceWithContext("com.sun.star.io.SequenceInputStream", context)
    istream.initialize((uno.ByteSequence(fbytes),))                         
    return istream

Now I can just use that stream.
