Is it possible to use a vector input or output with a block that uses the GRExtras interface? All of the examples for specifying the I/O signature for a Python block only show using a numpy type to specify the data width.
I also tried creating a C++ block and setting the sizeof_stream_item parameter of the gr_make_io_signature() to the total vector size as has been done in standard blocks that support vectors, but it doesn't appear to be working properly either. For example, I tried setting the size to 4096 bytes (vector of 1024 floats), but each time my work function gets called, input_items.size() is only returning 8, where I would have expected it to only be called when there was a full vector of data available? I suppose I could work around this with a vector to stream conversion block in front of it, but I just wanted to see if it is possible to directly accept vectors with the newer block interface.
