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.

Constructor & Destructor Documentation

gr::block_detail::~block_detail ( )

Member Function Documentation

void gr::block_detail::add_item_tag ( unsigned int  which_output,
const tag_t tag 
)

Adds a new tag to the given output stream.

Calls gr::buffer::add_item_tag(), which appends the tag onto its deque.

Parameters
which_outputan integer of which output stream to attach the tag
tagthe 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.

bool gr::block_detail::done ( ) const

void gr::block_detail::get_tags_in_range ( std::vector< tag_t > &  v,
unsigned int  which_input,
uint64_t  abs_start,
uint64_t  abs_end,
long  id 
)

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
va vector reference to return tags into
which_inputan integer of which input stream to pull from
abs_starta uint64 count of the start of the range of interest
abs_enda uint64 count of the end of the range of interest
idBlock ID
void gr::block_detail::get_tags_in_range ( std::vector< tag_t > &  v,
unsigned int  which_input,
uint64_t  abs_start,
uint64_t  abs_end,
const pmt::pmt_t key,
long  id 
)

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
va vector reference to return tags into
which_inputan integer of which input stream to pull from
abs_starta uint64 count of the start of the range of interest
abs_enda uint64 count of the end of the range of interest
keya PMT symbol to select only tags of this key

void gr::block_detail::produce ( int  which_output,
int  how_many_items 
)

Tell the scheduler how_many_items were produced on output stream which_output.

void gr::block_detail::produce_each ( int  how_many_items)

Tell the scheduler how_many_items were produced on each output stream.

void gr::block_detail::remove_item_tag ( unsigned int  which_input,
const tag_t tag,
long  id 
)

Removes a tag from the given input stream.

Calls gr::buffer::remove_item_tag(). The tag in question will then no longer appear on subsequent calls of get_tags_in_range().

Parameters
which_inputan integer of which input stream to remove the tag from
tagthe tag object to add
idThe unique block ID (use gr::block::unique_id())

Parameters
maska vector of ints of the core numbers available to this block.
int gr::block_detail::set_thread_priority ( int  priority)
