Member Typedef Documentation

typedef boost::shared_ptr<io_signature> gr::io_signature::sptr

Constructor & Destructor Documentation

gr::io_signature::~io_signature ( )

Member Function Documentation

static sptr gr::io_signature::make2 ( int  min_streams,
int  max_streams,
int  sizeof_stream_item1,
int  sizeof_stream_item2 
)
static

Create an i/o signature.

Parameters
min_streamsspecify minimum number of streams (>= 0)
max_streamsspecify maximum number of streams (>= min_streams or -1 -> infinite)
sizeof_stream_item1specify the size of the items in the first stream
sizeof_stream_item2specify the size of the items in the second and subsequent streams
static sptr gr::io_signature::make3 ( int  min_streams,
int  max_streams,
int  sizeof_stream_item1,
int  sizeof_stream_item2,
int  sizeof_stream_item3 
)
static

Create an i/o signature.

Parameters
min_streamsspecify minimum number of streams (>= 0)
max_streamsspecify maximum number of streams (>= min_streams or -1 -> infinite)
sizeof_stream_item1specify the size of the items in the first stream
sizeof_stream_item2specify the size of the items in the second stream
sizeof_stream_item3specify the size of the items in the third and subsequent streams
static sptr gr::io_signature::makev ( int  min_streams,
int  max_streams,
const std::vector< int > &  sizeof_stream_items 
)
static

Create an i/o signature.

Parameters
min_streamsspecify minimum number of streams (>= 0)
max_streamsspecify maximum number of streams (>= min_streams or -1 -> infinite)
sizeof_stream_itemsspecify the size of the items in the streams

If there are more streams than there are entries in sizeof_stream_items, the value of the last entry in sizeof_stream_items is used for the missing values. sizeof_stream_items must contain at least 1 entry.
