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 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_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.

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:

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
id	Block 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:

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
id	Block ID
