[protected, virtual]

true if the output shall be aligned, false if the input shall be aligned

Reimplemented from gr_tagged_stream_block.

int gr::blocks::repack_bits_bb_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.
