forestToNestedSets :: Forest a -> NestedSets a Source
Convert forest to nested sets
This function is the opposite of nestedSetsToForest
nestedSetsToForest :: NestedSets a -> Forest a Source
Convert nested sets to forest.
This function is the opposite of forestToNestedSets
nestedSetsStartPosition :: NestedSets a -> Maybe Position Source
Retrieve the starting position (iterator) of the nested set.
nestedSetsNextSiblingPosition :: NestedSets a -> Position -> Maybe Position Source
Advance the given position to the next sibling.
nestedSetsParentPosition :: NestedSets a -> Position -> Maybe Position Source
Retrieve the position's parent position.
nestedSetsFirstChildPosition :: NestedSets a -> Position -> Maybe Position Source
Advance the position to the first child node.
nestedSetsPositionValue :: NestedSets a -> Position -> Maybe a Source
Retrieve the value for the given Position.
nestedSetsPositionSetValue :: NestedSets a -> Position -> a -> NestedSets a Source
Set value for the Position on the given nested set.
Does not modify the given NestedSets if the Position cannot be found.
isNestedSetsPositionParent :: Position -> Position -> Bool Source
