Detailed Description

Simple concrete class for building hierarchical blocks.

This class assumes that there is at most a single block at the head of the chain and a single block at the end of the chain. Either head or tail may be None indicating a sink or source respectively.

If you needs something more elaborate than this, derive a new class from hier_block_base.

def gnuradio::gr::hier_block::hier_block::__init__	(		self,
			fg,
			head_block,
			tail_block
	)

Parameters:

	fg,:	The flow graph that contains this hierarchical block. fg: flow_graph
	head_block,:	the first block in the signal processing chain. head_block: None or subclass of gr.block or gr.hier_block_base
	tail_block,:	the last block in the signal processing chain. tail_block: None or subclass of gr.block or gr.hier_block_base

def gnuradio::gr::hier_block::hier_block::input_signature

(

self

)

Returns:

input signature of hierarchical block. gr.io_signature

Reimplemented from gnuradio::gr::hier_block::hier_block_base.

def gnuradio::gr::hier_block::hier_block::output_signature

(

self

)

Returns:

output signature of hierarchical block. gr.io_signature

Reimplemented from gnuradio::gr::hier_block::hier_block_base.

def gnuradio::gr::hier_block::hier_block::resolve_input_port	(		self,
			port_number
	)

Parameters:

port_number,:

which input port number to resolve to an endpoint. port_number: int

Returns:

: sequence of endpoints : sequence of endpoint

Note that an input port can resolve to more than one endpoint.

Reimplemented from gnuradio::gr::hier_block::hier_block_base.

def gnuradio::gr::hier_block::hier_block::resolve_output_port	(		self,
			port_number
	)

Parameters:

port_number,:

which output port number to resolve to an endpoint. port_number: int

Returns:

: endpoint : endpoint

Output ports resolve to a single endpoint.

Reimplemented from gnuradio::gr::hier_block::hier_block_base.
