Implementation details to support the signal processing abstractionThis class contains implementation detail that should be "out of sight" of almost all users of GNU Radio. This decoupling also means that we can make changes to the guts without having to recompile everything.

Detailed Description
Implementation details to support the signal processing abstraction
This class contains implementation detail that should be "out of sight" of almost all users of GNU Radio. This decoupling also means that we can make changes to the guts without having to recompile everything.

| void gr_block_detail::add_item_tag |
( |
unsigned int |
which_output, |
|
|
const gr_tag_t & |
tag |
|
) |
| |
Adds a new tag to the given output stream.
This takes the input parameters and builds a PMT tuple from it. It then calls gr_buffer::add_item_tag(pmt::pmt_t t), which appends the tag onto its deque.
- Parameters:
-
| which_output | an integer of which output stream to attach the tag |
| tag | the tag object to add |
| void gr_block_detail::consume |
( |
int |
which_input, |
|
|
int |
how_many_items |
|
) |
| |
Tell the scheduler how_many_items of input stream which_input were consumed.
| void gr_block_detail::consume_each |
( |
int |
how_many_items | ) |
|
Tell the scheduler how_many_items were consumed on each input stream.

const [inline] |
Given a [start,end), returns a vector of all tags in the range.
Pass-through function to gr_buffer_reader to get a vector of tags in given range. Range of counts is from start to end-1.
Tags are tuples of: (item count, source id, key, value)
- Parameters:
-
| v | a vector reference to return tags into |
| which_input | an integer of which input stream to pull from |
| abs_start | a uint64 count of the start of the range of interest |
| abs_end | a uint64 count of the end of the range of interest |
Given a [start,end), returns a vector of all tags in the range with a given key.
Calls get_tags_in_range(which_input, abs_start, abs_end) to get a vector of tags from the buffers. This function then provides a secondary filter to the tags to extract only tags with the given 'key'.
Tags are tuples of: (item count, source id, key, value)
- Parameters:
-
| v | a vector reference to return tags into |
| which_input | an integer of which input stream to pull from |
| abs_start | a uint64 count of the start of the range of interest |
| abs_end | a uint64 count of the end of the range of interest |
| key | a PMT symbol to select only tags of this key |
