Kind

class

Source

src/delegates/GpuForcePositionDelegate.js:5279

Description

Position delegate used by GPU force layouts.

Signature

export class GpuForcePositionDelegate extends PositionDelegate {

Parameters

Name	Type	Attributes	Default	Description
options	Object	optional		GPU force layout delegate options and resource handles.

Returns

Delegate that synchronizes graph topology to GPU buffers and exposes position snapshots to Helios renderers.

Type GpuForcePositionDelegate

Notes

This is a low-level extension point. Most applications configure it indirectly through GpuForceLayout or LayoutBehavior.

Filtering And State

Graph filtering and interaction state. When active, FilterBehavior and SelectionBehavior coordinate this area.

resetDynamicStateFromNetwork(context = {}) → {this}

Source: src/delegates/GpuForcePositionDelegate.js:5464

Updates the dynamic state from network state on the current instance.

Parameters

Name	Type	Attributes	Default	Description
context		optional	{}	Value passed to resetDynamicStateFromNetwork.

Returns

This instance.

Type this

Network And Persistence

Network replacement, serialization, and visualization state persistence. ExporterBehavior and InterfaceBehavior can surface parts of this flow in the UI.

captureNetworkVersionSnapshot(network)

Source: src/delegates/GpuForcePositionDelegate.js:5523

Configures or reads capture network version snapshot.

Parameters

Name	Type	Attributes	Default	Description
network	HeliosNetwork			Network instance to read from or mutate.

Source: src/delegates/GpuForcePositionDelegate.js:6257

Configures or reads synchronize node positions to network.

Parameters

Name	Type	Attributes	Default	Description
context		optional	{}	Value passed to synchronizeNodePositionsToNetwork.

Layout And Positions

Layout selection, position sources, interpolation, and position snapshots. LayoutBehavior handles the built-in layout UI.

getNodePositionView(context = {})

Source: src/delegates/GpuForcePositionDelegate.js:5941

Returns the current node position view value or state.

Parameters
