bool llvm::IntervalMapImpl::Path::atBegin ( ) const

inline

atBegin - Return true if path is at begin().

Definition at line 894 of file IntervalMap.h.

bool llvm::IntervalMapImpl::Path::atLastEntry ( unsigned Level ) const

inline

atLastEntry - Return true if the path is at the last entry of the node at Level.

Parameters

Level Node to examine.

Definition at line 904 of file IntervalMap.h.

void llvm::IntervalMapImpl::Path::fillLeft ( unsigned Height )

inline

fillLeft - Grow path to Height by taking leftmost branches.

Parameters

Height The target height.

Definition at line 878 of file IntervalMap.h.

getLeftSibling - Get the left sibling node at Level, or a null NodeRef.

Parameters

Level Get the sibling to node(Level).

Returns: Left sibling, or NodeRef().

NodeRef llvm::IntervalMapImpl::Path::getRightSibling ( unsigned Level ) const

getLeftSibling - Get the left sibling node at Level, or a null NodeRef.

Parameters

Level Get the sinbling to node(Level).

Returns: Left sibling, or NodeRef().

unsigned llvm::IntervalMapImpl::Path::height ( ) const

inline

height - Return the height of the tree corresponding to this path. This matches map->height in a full path.

void llvm::IntervalMapImpl::Path::legalizeForInsert ( unsigned Level )

inline

legalizeForInsert - Prepare the path for an insertion at Level. When the path is at end(), node(Level) may not be a legal node. legalizeForInsert ensures that node(Level) is real by moving back to the last node at Level, and setting offset(Level) to size(Level) if required.

Parameters

Level The level where an insertion is about to take place.

Definition at line 913 of file IntervalMap.h.

void llvm::IntervalMapImpl::Path::moveLeft ( unsigned Level )

moveLeft - Move path to the left sibling at Level. Leave nodes below Level unaltered.

Parameters

Level Move node(Level).

void llvm::IntervalMapImpl::Path::moveRight ( unsigned Level )

moveRight - Move path to the left sibling at Level. Leave nodes below Level unaltered.

Parameters

Level Move node(Level).

inline

push - Add entry to path.

Parameters

Node	Node to add, should be subtree(path.size()-1).
Offset	Offset into Node.

Parameters

Root	The new root node.
Size	Number of entries in the new root.
Offsets	Offsets into the root and first branch nodes.
