clear()

void llvm::OutlinedHashTree::clear ( )

inline

Release all hash nodes except the root hash node.

Definition at line 62 of file OutlinedHashTree.h.

References assert(), getRoot(), and llvm::HashNode::Successors.

depth()

size_t OutlinedHashTree::depth

(

)

const

Returns

the depth of a OutlinedHashTree by traversing it.

Definition at line 59 of file OutlinedHashTree.cpp.

References llvm::Depth, N, Size, and walkGraph().

empty()

bool llvm::OutlinedHashTree::empty ( )

inline

Returns

true if the hash tree has only the root node.

Definition at line 68 of file OutlinedHashTree.h.

References size().

find()

std::optional< unsigned > OutlinedHashTree::find

(

const HashSequence &

Sequence

)

const

Returns

the matching count if Sequence exists in the OutlinedHashTree.

Definition at line 119 of file OutlinedHashTree.cpp.

References getRoot(), I, llvm::HashNode::Successors, and llvm::HashNode::Terminals.

getRoot() [1/2]

HashNode * llvm::OutlinedHashTree::getRoot ( )

inline

Definition at line 81 of file OutlinedHashTree.h.

getRoot() [2/2]

const HashNode * llvm::OutlinedHashTree::getRoot ( ) const

inline

Returns

the root hash node of a OutlinedHashTree.

Definition at line 80 of file OutlinedHashTree.h.

insert()

void OutlinedHashTree::insert

(

const HashSequencePair &

SequencePair

)

Inserts a Sequence into the this tree.

The last node in the sequence will increase Terminals.

References getRoot(), llvm::HashNode::Hash, I, llvm::HashNode::Successors, and llvm::HashNode::Terminals.

merge()

void OutlinedHashTree::merge

(

const OutlinedHashTree *

OtherTree

)

Merge a OtherTree into this Tree.

Definition at line 90 of file OutlinedHashTree.cpp.

References getRoot(), llvm::HashNode::Hash, and I.

size()

size_t OutlinedHashTree::size

(

bool

GetTerminalCountOnly = false

)

const

Returns

the size of a OutlinedHashTree by traversing it. If GetTerminalCountOnly is true, it only counts the terminal nodes (meaning it returns the the number of hash sequences in the OutlinedHashTree).

Definition at line 51 of file OutlinedHashTree.cpp.

walkGraph()

void OutlinedHashTree::walkGraph	(	NodeCallbackFn	CallbackNode,
		EdgeCallbackFn	CallbackEdge = nullptr,
		bool	SortedWalk = false
	)		const

Walks every edge and node in the OutlinedHashTree and calls CallbackEdge for the edges and CallbackNode for the nodes with the stable_hash for the source and the stable_hash of the sink for an edge.

These generic callbacks can be used to traverse a OutlinedHashTree for the purpose of print debugging or serializing it.
