Constructor & Destructor Documentation

__init__()

linker.BusLinker.__init__	(		self,
		str	bus_name )

Member Function Documentation

_link_priority_group()

linker.BusLinker._link_priority_group ( self, int priority )

protected

Pass 2: Assign IDs to dynamic messages in this priority group.
Respects the 'Water Level' (next_avail_id) and skips reserved overrides.

Here is the caller graph for this function:

_validate_overrides()

linker.BusLinker._validate_overrides ( self )

protected

Pass 1: Validate that overrides respect priority monotonicity.
An override in Priority 0 (e.g. 0x10) must be < an override in Priority 1 (e.g. 0x20).

Here is the caller graph for this function:

add_message()

linker.BusLinker.add_message	(		self,
		Message	msg )

link()

linker.BusLinker.link

(

self

)
