bool gr::blocks::copy_impl::check_topology |
( |

ninputs, |

int |
noutputs |

) |
| |
|
virtual |
Confirm that ninputs and noutputs is an acceptable combination.
- Parameters
-
ninputs | number of input streams connected |
noutputs | number of output streams connected |
- Returns
- true if this is a valid configuration for this block.
This function is called by the runtime system whenever the topology changes. Most classes do not need to override this. This check is in addition to the constraints specified by the input and output gr_io_signatures.
Reimplemented from gr_basic_block.

Estimate input requirements given output request.
- Parameters
-
noutput_items | number of output items to produce |
ninput_items_required | number of input items required on each input stream |
Given a request to product noutput_items
, estimate the number of data items required on each input stream. The estimate doesn't have to be exact, but should be close.
Reimplemented from gr_block.
compute output items from input items
- Parameters
-
noutput_items | number of output items to write on each output stream |
ninput_items | number of input items available on each input stream |
input_items | vector of pointers to the input items, one entry per input stream |
output_items | vector of pointers to the output items, one entry per output stream |
- Returns
- number of items actually written to each output stream, or -1 on EOF. It is OK to return a value less than noutput_items. -1 <= return value <= noutput_items
general_work must call consume or consume_each to indicate how many items were consumed on each input stream.
