Member Function Documentation

◆ all_max_output_buffer_p()

bool gr::hier_block2::all_max_output_buffer_p ( void )

Get if all block max buffers should be set.

this returns whether all the block max output buffers should be set or just the block ports connected to the hier ports.

◆ all_min_output_buffer_p()

bool gr::hier_block2::all_min_output_buffer_p ( void )

Get if all block min buffers should be set.

this returns whether all the block min output buffers should be set or just the block ports connected to the hier ports.

◆ connect() [1/2]

void gr::hier_block2::connect ( basic_block_sptr block )

Add a stand-alone (possibly hierarchical) block to internal graph.

This adds a gr-block or hierarchical block to the internal graph without wiring it to anything else.

◆ connect() [2/2]

void gr::hier_block2::connect	(	basic_block_sptr	src,
		int	src_port,
		basic_block_sptr	dst,
		int	dst_port
	)

Add gr-blocks or hierarchical blocks to internal graph and wire together.

This adds (if not done earlier by another connect) a pair of gr-blocks or hierarchical blocks to the internal flowgraph, and wires the specified output port to the specified input port.

◆ disconnect() [1/2]

void gr::hier_block2::disconnect ( basic_block_sptr block )

Remove a gr-block or hierarchical block from the internal flowgraph.

This removes a gr-block or hierarchical block from the internal flowgraph, disconnecting it from other blocks as needed.

◆ disconnect() [2/2]

void gr::hier_block2::disconnect	(	basic_block_sptr	src,
		int	src_port,
		basic_block_sptr	dst,
		int	dst_port
	)

Disconnect a pair of gr-blocks or hierarchical blocks in internal flowgraph.

This disconnects the specified input port from the specified output port of a pair of gr-blocks or hierarchical blocks.

◆ disconnect_all()

void gr::hier_block2::disconnect_all ( )

Disconnect all connections in the internal flowgraph.

This call removes all output port to input port connections in the internal flowgraph.

◆ has_msg_port()

bool gr::hier_block2::has_msg_port ( pmt::pmt_t which_port )

inlineoverridevirtual

Reimplemented from gr::basic_block.

References gr::basic_block::has_msg_port().

◆ lock()

virtual void gr::hier_block2::lock ( )

virtual

Lock a flowgraph in preparation for reconfiguration. When an equal number of calls to lock() and unlock() have occurred, the flowgraph will be reconfigured.

N.B. lock() and unlock() may not be called from a flowgraph thread (E.g., gr::block::work method) or deadlock will occur when reconfiguration happens.

Reimplemented in gr::top_block.

◆ log_level()

std::string gr::hier_block2::log_level ( )

overridevirtual

Get the logger's output level.

Implements gr::basic_block.

◆ max_output_buffer()

int gr::hier_block2::max_output_buffer ( size_t port = 0 )

Returns max buffer size (itemcount) on output port i.

◆ message_port_is_hier()

bool gr::hier_block2::message_port_is_hier ( pmt::pmt_t port_id )

inlineoverridevirtual

Reimplemented from gr::basic_block.

bool gr::hier_block2::message_port_is_hier_in ( pmt::pmt_t port_id )

inlineoverridevirtual

Reimplemented from gr::basic_block.

References pmt::list_has().

◆ message_port_is_hier_out()

bool gr::hier_block2::message_port_is_hier_out ( pmt::pmt_t port_id )

inlineoverridevirtual

Reimplemented from gr::basic_block.

References pmt::list_has().

◆ message_port_register_hier_in()

void gr::hier_block2::message_port_register_hier_in ( pmt::pmt_t port_id )

inline

References pmt::list_add(), and pmt::list_has().

void gr::hier_block2::message_port_register_hier_out ( pmt::pmt_t port_id )

inline

References pmt::dict_has_key(), pmt::list_add(), and pmt::list_has().

◆ min_output_buffer()

int gr::hier_block2::min_output_buffer ( size_t port = 0 )

Returns min buffer size (itemcount) on output port i.

◆ msg_connect() [1/2]

void gr::hier_block2::msg_connect	(	basic_block_sptr	src,
		pmt::pmt_t	srcport,
		basic_block_sptr	dst,
		pmt::pmt_t	dstport
	)

Add gr-blocks or hierarchical blocks to internal graph and wire together.

This adds (if not done earlier by another connect) a pair of gr-blocks or hierarchical blocks to the internal message port subscription

◆ msg_connect() [2/2]

void gr::hier_block2::msg_connect	(	basic_block_sptr	src,
		std::string	srcport,
		basic_block_sptr	dst,
		std::string	dstport
	)

◆ msg_disconnect() [1/2]

void gr::hier_block2::msg_disconnect	(	basic_block_sptr	src,
		pmt::pmt_t	srcport,
		basic_block_sptr	dst,
		pmt::pmt_t	dstport
	)

◆ msg_disconnect() [2/2]

void gr::hier_block2::msg_disconnect	(	basic_block_sptr	src,
		std::string	srcport,
		basic_block_sptr	dst,
		std::string	dstport
	)

◆ processor_affinity()

std::vector<int> gr::hier_block2::processor_affinity ( )

overridevirtual

Get the current processor affinity.

This returns the processor affinity value for the first block in the hier_block2's list of blocks with the assumption that they have always only been set through the hier_block2's interface. If any block has been individually set, then this call could be misleading.

Implements gr::basic_block.

◆ self()

opaque_self gr::hier_block2::self ( )

Return an object, representing the current block, which can be passed to connect.

The returned object may only be used as an argument to connect or disconnect. Any other use of self() results in unspecified (erroneous) behavior.

◆ set_log_level()

void gr::hier_block2::set_log_level ( const std::string & level )

overridevirtual

Set the logger's output level.

Sets the level of the logger for all connected blocks. This takes a string that is translated to the standard levels and can be (case insensitive):

off , notset
debug
info
notice
warn
error
crit
alert
fatal
emerg

Implements gr::basic_block.

◆ set_max_output_buffer() [1/2]

void gr::hier_block2::set_max_output_buffer ( int max_output_buffer )

Sets max buffer size (itemcount) on all output ports.

◆ set_max_output_buffer() [2/2]

void gr::hier_block2::set_max_output_buffer	(	size_t	port,
		int	max_output_buffer
	)

Sets max buffer size (itemcount) on output port port.

◆ set_min_output_buffer() [1/2]

void gr::hier_block2::set_min_output_buffer ( int min_output_buffer )

Sets min buffer size (itemcount) on all output ports.

◆ set_min_output_buffer() [2/2]

void gr::hier_block2::set_min_output_buffer	(	size_t	port,
		int	min_output_buffer
	)

Sets min buffer size (itemcount) on output port port.

◆ set_processor_affinity()

void gr::hier_block2::set_processor_affinity ( const std::vector< int > & mask )

overridevirtual

Set the affinity of all blocks in hier_block2 to processor core n.

Parameters

mask	a vector of ints of the core numbers available to this block.

Implements gr::basic_block.

◆ to_hier_block2()

hier_block2_sptr gr::hier_block2::to_hier_block2 ( )

◆ unlock()

virtual void gr::hier_block2::unlock ( )

virtual

Unlock a flowgraph in preparation for reconfiguration. When an equal number of calls to lock() and unlock() have occurred, the flowgraph will be reconfigured.

N.B. lock() and unlock() may not be called from a flowgraph thread (E.g., gr::block::work method) or deadlock will occur when reconfiguration happens.

Reimplemented in gr::top_block.

◆ unset_processor_affinity()

void gr::hier_block2::unset_processor_affinity ( )

overridevirtual

Remove processor affinity for all blocks in hier_block2.

Implements gr::basic_block.
