Detailed Description

a spin-off search path through the trie, which can deal with ambiguous AAs and mismatches

Constructor & Destructor Documentation

ACScout() [1/2]

ACScout ( )

delete

No default C'tor.

ACScout() [2/2]

ACScout	(	const char *	query_pos,
		Index	tree_pos,
		uint8_t	max_aa,
		uint8_t	max_mm,
		uint8_t	max_prefix_loss
	)

C'tor with arguments.

Member Function Documentation

nextValidAA()

AA nextValidAA

(

)

Return the next valid AA in the query. If the query was fully traversed, an invalid AA is returned. This moves the internal iterator for the query forwards.

textPos()

size_t textPos

(

const ACTrieState &

state

)

const

Where in the text are we currently?
