count

HierarchyRectangularNode.count

Defined in

node_modules/@types/d3-hierarchy/index.d.ts:112

each

each<T>(func, that?): DonutNode

Invokes the specified function for node and each descendant in breadth-first order, such that a given node is only visited if all nodes of lesser depth have already been visited, as well as all preceding nodes of the same depth.

Type parameters

Name Type
T undefined

Parameters

Name Type Description
func (node: DonutNode, index: number, thisNode: DonutNode) => void The specified function is passed the current descendant, the zero-based traversal index, and this node.
that? T If that is specified, it is the this context of the callback.

Returns

DonutNode

Inherited from

HierarchyRectangularNode.each

Defined in

node_modules/@types/d3-hierarchy/index.d.ts:138


eachAfter

eachAfter<T>(func, that?): DonutNode

Invokes the specified function for node and each descendant in post-order traversal, such that a given node is only visited after all of its descendants have already been visited.

Type parameters

Name Type
T undefined

Parameters

Name Type Description
func (node: DonutNode, index: number, thisNode: DonutNode) => void The specified function is passed the current descendant, the zero-based traversal index, and this node.
that? T If that is specified, it is the this context of the callback.

Returns

DonutNode

Inherited from

HierarchyRectangularNode.eachAfter

Defined in

node_modules/@types/d3-hierarchy/index.d.ts:148


eachBefore

eachBefore<T>(func, that?): DonutNode

Invokes the specified function for node and each descendant in pre-order traversal, such that a given node is only visited after all of its ancestors have already been visited.

Type parameters

Name Type
T undefined

Parameters

func (node: DonutNode, index: number, thisNode: DonutNode) => void The specified function is passed the current descendant, the zero-based traversal index, and this node.
that? T If that is specified, it is the this context of the callback.

find

find(filter): DonutNode

Returns the first node in the hierarchy from this node for which the specified filter returns a truthy value. undefined if no such node is found.

Parameters

Name Type Description
filter (node: DonutNode) => boolean Filter.

Returns

DonutNode

Inherited from

HierarchyRectangularNode.find

Defined in

node_modules/@types/d3-hierarchy/index.d.ts:84


leaves

leaves(): DonutNode[]

Returns the array of leaf nodes in traversal order; leaves are nodes with no children.

Inherited from

HierarchyRectangularNode.leaves

Defined in

node_modules/@types/d3-hierarchy/index.d.ts:78


links(): HierarchyRectangularLink<any>[]

Returns an array of links for this node, where each link is an object that defines source and target properties. The source of each link is the parent node, and the target is a child node.

Returns

HierarchyRectangularLink<any>[]

HierarchyRectangularNode.links

Defined in

node_modules/@types/d3-hierarchy/index.d.ts:430


path

path(target): DonutNode[]

Returns the shortest path through the hierarchy from this node to the specified target node. The path starts at this node, ascends to the least common ancestor of this node and the target node, and then descends to the target node.

Parameters

Name Type Description
target DonutNode The target node.

Returns

DonutNode[]

Inherited from

HierarchyRectangularNode.path

Defined in

node_modules/@types/d3-hierarchy/index.d.ts:92


sort

sort(compare): DonutNode

Sorts the children of this node, if any, and each of this node’s descendants’ children, in pre-order traversal using the specified compare function, and returns this node.

Parameters

Name Type Description
compare (a: DonutNode, b: DonutNode) => number The compare function is passed two nodes a and b to compare. If a should be before b, the function must return a value less than zero; if b should be before a, the function must return a value greater than zero; otherwise, the relative order of a and b are not specified. See array.sort for more.

Returns

DonutNode

Inherited from

HierarchyRectangularNode.sort

Defined in

node_modules/@types/d3-hierarchy/index.d.ts:123


sum

sum(value): DonutNode

Evaluates the specified value function for this node and each descendant in post-order traversal, and returns this node. The node.value property of each node is set to the numeric value returned by the specified function plus the combined value of all descendants.

Parameters

Name Type Description
value (d: any) => number The value function is passed the node’s data, and must return a non-negative number.

Returns

DonutNode

Inherited from

HierarchyRectangularNode.sum
