LayoutTransition

class LayoutTransition<T>(from: TreeLayoutResult<T>, to: TreeLayoutResult<T>)(source)

Represents a transition between two layout states, enabling animation by interpolating node positions at a given progress fraction.

Nodes present only in from are treated as exiting (animate to their last known position). Nodes present only in to are treated as entering (animate from their target position).

Parameters

from

The starting layout state.

The ending layout state.

Type Parameters

The node type of the external tree.

Constructors

LayoutTransition

constructor(from: TreeLayoutResult<T>, to: TreeLayoutResult<T>)

Properties

allNodes

val allNodes: Set<T>

All nodes involved in either the start or end state.

enteringNodes

val enteringNodes: Set<T>

Nodes only in to (added in the new layout).

exitingNodes

val exitingNodes: Set<T>

Nodes only in from (removed in the new layout).

persistentNodes

val persistentNodes: Set<T>

Nodes present in both states.

Functions

interpolate

fun interpolate(progress: Float): TreeLayoutResult<T>

Returns an interpolated layout at the given progress (0.0 = from, 1.0 = to).
