gr::tag_t Struct Reference

#include <gnuradio/tags.h>

Public Member Functions
bool	operator== (const tag_t &t) const
	equality comparison. Compares all details, except marked_delete
	tag_t ()
	tag_t (const tag_t &rhs)
	Copy constructor; constructs identical tag, but doesn't copy marked_delete.
tag_t &	operator= (const tag_t &rhs)
	~tag_t ()

Static Public Member Functions
static bool	offset_compare (const tag_t &x, const tag_t &y)
	Comparison function to test which tag, x or y, came first in time.

Public Attributes
uint64_t	offset
	the item tag occurred at (as a uint64_t)
pmt::pmt_t	key
	the key of tag (as a PMT symbol)
pmt::pmt_t	value
	the value of tag (as a PMT)
pmt::pmt_t	srcid
	the source ID of tag (as a PMT)
std::vector< long >	marked_deleted
	Used by gr_buffer to mark a tagged as deleted by a specific block. You can usually ignore this.

Friends
bool	operator< (const tag_t &x, const tag_t &y)
	Comparison function to test which tag, x or y, came first in time.
