Detailed Description

Renders a NodeBranch using ImGui/ImNodes with 4 sections.

The renderer is stateless with respect to node data: it reads from the NodeBranchData passed each frame. Internal state is limited to hover/click tracking for interaction.

Usage:

NodeBranchRenderer renderer(registry, pinManager);
// In the ImNodes frame:
renderer.RenderNode(nodeID, branchData);

Resets the last-clicked condition index to -1.

Definition at line 216 of file NodeBranchRenderer.h.

References m_lastClickedCondition.

◆ ClearRefreshPending()

void Olympe::NodeBranchRenderer::ClearRefreshPending ( )

inline

Clears the refresh-pending flag (called after refresh is complete).

Definition at line 254 of file NodeBranchRenderer.h.

References m_refreshPending.

◆ GetLastClickedConditionIndex()

int Olympe::NodeBranchRenderer::GetLastClickedConditionIndex ( ) const

inline

Returns the index of the last condition row that was clicked, or -1 if none.

Definition at line 211 of file NodeBranchRenderer.h.

References m_lastClickedCondition.

◆ IsRefreshPending()

bool Olympe::NodeBranchRenderer::IsRefreshPending ( ) const

inline

Returns true if any preset change notification is pending (dirty).

Definition at line 249 of file NodeBranchRenderer.h.

References m_refreshPending.

◆ NotifyPresetChanged()

void Olympe::NodeBranchRenderer::NotifyPresetChanged ( const std::string & changedPresetID )

Notifies the renderer that a preset has been updated.

Marks the node as needing a label refresh. The next call to RenderNode() will recompute preview strings from the registry.

Parameters

changedPresetID UUID of the modified preset.

Definition at line 387 of file NodeBranchRenderer.cpp.

References m_refreshPending.

◆ operator=()

NodeBranchRenderer & Olympe::NodeBranchRenderer::operator= ( const NodeBranchRenderer & )

delete

◆ RenderConditionsSection()

void Olympe::NodeBranchRenderer::RenderConditionsSection ( const NodeBranchData & data )

Renders Section 3: read-only conditions preview (green text).

Each condition is displayed in the format: " [mHealth] <= [2]" "And [mSpeed] <= [100.00]" Hovering shows a tooltip; clicking fires OnConditionClicked.

Parameters

data	Node data.

◆ RenderDynamicPinsSection()

void Olympe::NodeBranchRenderer::RenderDynamicPinsSection	(	const NodeBranchData &	data,
		const std::unordered_set< int > &	connectedAttrIDs = `{}`
	)

Renders Section 4: dynamic data pins (yellow, conditional).

Only rendered when data.dynamicPins is non-empty. Format: "In #<idx>[L/R]: <condPreview>"

Parameters

data	Node data.
connectedAttrIDs	Set of connected attribute IDs (for filled/outlined shape).

◆ RenderExecPinsSection()

void Olympe::NodeBranchRenderer::RenderExecPinsSection ( const NodeBranchData & data )

Renders Section 2: static exec pins (In / Then / Else).

Shows "In" on the left and "Then" / "Else" on the right. These pins are NEVER editable from this section.

Parameters

data	Node data.

Definition at line 178 of file NodeBranchRenderer.cpp.

◆ RenderNode()

void Olympe::NodeBranchRenderer::RenderNode	(	const NodeBranchData &	data,
		const std::unordered_set< int > &	connectedAttrIDs = `{}`
	)

Renders the full NodeBranch node in the current ImNodes context.

Must be called between ImNodes::BeginNode() and ImNodes::EndNode(). In headless builds this is a no-op.

Parameters

data	Current snapshot of the node's data.
connectedAttrIDs	Set of attribute IDs that are currently connected. Pins in this set are rendered filled; others outlined.

private

Definition at line 403 of file NodeBranchRenderer.cpp.

◆ RenderTitleSection()

void Olympe::NodeBranchRenderer::RenderTitleSection ( const NodeBranchData & data )

Renders Section 1: title bar with blue background.

Displays the node name on a blue-highlighted background row.

Parameters

data	Node data.

Here is the call graph for this function:

◆ SetupDynamicPinConnectors()

void Olympe::NodeBranchRenderer::SetupDynamicPinConnectors ( const NodeBranchData & data )

Sets up ImNodes connectors for each dynamic pin.

Call this within an ImNodes::BeginNode() / ImNodes::EndNode() block so each yellow dynamic pin becomes drag-connectable in the graph editor. Each pin receives a connector ID derived from pin.id.

In headless / test builds this is a no-op.

Parameters

data	Node data (dynamicPins are iterated).

Here is the call graph for this function:

◆ TriggerPinRegeneration()

void Olympe::NodeBranchRenderer::TriggerPinRegeneration ( std::vector< NodeConditionRef > & conditionRefs )

Regenerates dynamic data pins from an updated condition list.

Call this after the user confirms changes in the edit modal so the canvas reflects the new pin set on the next render frame.

Delegates to DynamicDataPinManager::RegeneratePinsFromConditions() so the host does not need a direct reference to the pin manager.

Parameters

conditionRefs Node's condition list (modified in-place to store updated pin IDs).
