Member Function Documentation

void gr::digital::ofdm_frame_equalizer_vcvc_impl::parse_length_tags	(	const std::vector< std::vector< gr_tag_t > > &	tags,
		gr_vector_int &	n_input_items_reqd
	)		[protected, virtual]

Parse all tags on the first sample of a PDU, return the number of items per input and prune the length tags.

In most cases, you don't need to override this, unless the number of items read is not directly coded in one single tag.

Default behaviour:

• Go through all input ports
• On every input port, search for the tag with the key specified in length_tag_key
• Copy that value as an int to the corresponding position in n_input_items_reqd
• Remove the length tag.

Parameters:

[in]	tags	All the tags found on the first item of every input port.
[out]	n_input_items_reqd	Number of items which will be read from every input

Reimplemented from gr_tagged_stream_block.

int gr::digital::ofdm_frame_equalizer_vcvc_impl::work	(	int	noutput_items,
		gr_vector_int &	ninput_items,
		gr_vector_const_void_star &	input_items,
		gr_vector_void_star &	output_items
	)		[virtual]

Just like gr_block::general_work, but makes sure the input is valid.

The user must override work to define the signal processing code. Check the documentation for general_work() to see what happens here.

Like gr_sync_block, this calls consume() for you (it consumes ninput_items[i] items from the i-th port).

A note on tag propagation: The PDU length tags are handled by other functions, but all other tags are handled just as in any other gr_block. So, most likely, you either set the tag propagation policy to TPP_DONT and handle the tag propagation manually, or you propagate tags through the scheduler and don't do anything here.

Parameters:

noutput_items	The size of the writable output buffer
ninput_items	The exact size of the items on every input for this particular PDU. These will be consumed if a length tag key is provided!
input_items	See gr_block
output_items	See gr_block

Implements gr_tagged_stream_block.
