How we keep track of the readers of a gr_buffer.
gr_buffer_reader::~gr_buffer_reader |
( |

|
Return buffer this reader reads from.
bool gr_buffer_reader::done |

Given a [start,end), returns a vector all tags in the range.
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 |
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 |
int gr_buffer_reader::items_available |
( |
) | |
const |
Return number of items available for reading.
Return the block that reads via this reader.
int gr_buffer_reader::max_possible_items_available |
( |
) | |
const |
|
inline |
Return maximum number of items that could ever be available for reading. This is used as a sanity check in the scheduler to avoid looping forever.
uint64_t gr_buffer_reader::nitems_read |
( |
) | |
|
|
inline |
const void* gr_buffer_reader::read_pointer |
( |
) | |
|
return pointer to read buffer.
The return value points to items_available() number of items
void gr_buffer_reader::set_done |
( |
bool |
done) | |
|
|
inline |
void gr_buffer_reader::update_read_pointer |
( |
int |
nitems) | |
|
Create a new gr_buffer_reader and attach it to buffer buf
.
- Parameters
-
buf | is the buffer the gr_buffer_reader reads from. |
nzero_preload | – number of zero items to "preload" into buffer. |
link | is the block that reads from the buffer using this gr_buffer_reader. |
