Detailed Description

A node in the AhoCorasick trie. Internally manages the suffix link and an index where its children start (this relies on the trie being stored in BFS order)

Member Typedef Documentation

◆ ChildCountType

using ChildCountType = uint8_t

Constructor & Destructor Documentation

◆ ACNode() [1/2]

ACNode ( )

inline

Default C'tor.

◆ ACNode() [2/2]

ACNode	(	const AA	label,
		const uint8_t	depth
	)

inline

C'tor from an edge label (from parent to this node) and a depth in the tree.

Member Data Documentation

◆ depth_and_hits

DepthHits depth_and_hits

depth of node in the tree and one bit if a needle ends in this node or any of its suffices

◆ edge

AA edge {0}

what is the edge label (from parent to this node)

◆ first_child

Index first_child {0}

which node contains our first child node (if tree is in BFS order)

◆ nr_children

ChildCountType nr_children = 0

number of children (if tree is in BFS order); // we could also go with a bitfield of size 22, but that would cost extra 3 bytes per node

◆ suffix

Index suffix {0}

which node is our suffix?
