Detailed Description

stores information about a block

A block corresponds to a slice of the permutation array. As the number of blocks is initially unknown, we will allocate instances of this class dynamically.

The slice in the permutation array containing the states of the block is subdivided into the following subslices (in this order):

unmarked bottom states
marked bottom states (initially empty)
unmarked non-bottom states
marked non-bottom states (initially empty)

A state should be marked iff it is a predecessor of the current splitter (through a strong transition). The marking is later extended to the R-states; that are the states with a weak transition to the splitter.

(During the execution of some functions, blocks are subdivided further; however, as these subdivisions are local to a single function, they are not stored here.)

Note that block_t uses the default destructor; therefore, if simple_list is trivially destructible, so is block_t.

Constructor & Destructor Documentation

◆ block_t()

mcrl2::lts::detail::bisim_dnj::block_t::block_t	(	permutation_entry *const	new_begin,
		permutation_entry *const	new_end,
		state_type const	new_seqnr
	)

inline

constructor

The constructor initialises the block to: all states are bottom states, no state is marked.

Parameters

new_begin	initial iterator to the first state of the block
new_end	initial iterator past the last state of the block
new_seqnr	is the sequence number of the new block

Member Function Documentation

◆ bottom_size()

state_type mcrl2::lts::detail::bisim_dnj::block_t::bottom_size ( ) const

inline

provides the number of bottom states in the block

Definition at line 404 of file liblts_bisim_dnj.h.

◆ debug_id()

template<class LTS_TYPE >

std::string mcrl2::lts::detail::bisim_dnj::block_t::debug_id ( const bisim_partitioner_dnj< LTS_TYPE > & partitioner ) const

inline

Definition at line 498 of file liblts_bisim_dnj.h.

◆ mark()

bool mcrl2::lts::detail::bisim_dnj::block_t::mark ( permutation_entry *const s )

inline

mark a state

Marking is done by moving the state to the slice of the marked bottom or non-bottom states of the block.

Parameters

s	the state that has to be marked

Returns: true iff the state was not marked before

◆ mark_nonbottom()

bool mcrl2::lts::detail::bisim_dnj::block_t::mark_nonbottom ( permutation_entry *const s )

inline

mark a non-bottom state

Marking is done by moving the state to the slice of the marked non-bottom states of the block.

Parameters

s	the non-bottom state that has to be marked

Returns: true iff the state was not marked before

Definition at line 451 of file liblts_bisim_dnj.h.
