Detailed Description

Hierarchical container class for gr_block's and gr_hier_block2's.

Member Typedef Documentation

typedef gr_basic_block_sptr gr_hier_block2::opaque_self

typedef for object returned from self().

This type is only guaranteed to be passable to connect and disconnect. No other assumptions should be made about it.

Member Function Documentation

void gr_hier_block2::connect

(

gr_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.

void gr_hier_block2::connect	(	gr_basic_block_sptr	src,
		int	src_port,
		gr_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.

void gr_hier_block2::disconnect

(

gr_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.

void gr_hier_block2::disconnect	(	gr_basic_block_sptr	src,
		int	src_port,
		gr_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.

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.

gr_flat_flowgraph_sptr gr_hier_block2::flatten

(

)

const

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.

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.

gr_hier_block2_sptr gr_hier_block2::to_hier_block2

(

)

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.
