Package ai.mindconnect.ui.ext.diagram

Class UiDiagramShape

java.lang.Object

ai.mindconnect.ui.ext.diagram.UiDiagramShape

public final class UiDiagramShape
extends Object

Built-in shape identifiers known to the diagram renderer. These are the geometric primitives the extension ships handlers for — kept deliberately narrow and domain-agnostic so the extension stays reusable.

Why constants, not an enum

UiDiagramNode.shape is a plain String, not an enum, so consumers can register their own shape names at runtime via the front-end registry (registerShape() in extension.ts). Closing the type over a Java enum here would force every new shape into a JAR rebuild even though the rendering side is already plug-able.

Domain-specific shapes

Workflow-flavoured concepts like "decision", "fork", "event-start" are not primitives — they're domain concepts that map onto a primitive plus styling. Those live in mc-workflow-ui-diagram's WorkflowShapes helper, not here.

To render with one of these constants:

   var n = new UiDiagramNode();
   n.setShape(UiDiagramShape.ROUNDED_RECT);
   n.setShapeClass("wf-action");

Fields

Modifier and Type	Field	Description
static final String	BAR	Thin horizontal (or vertical, depending on aspect ratio) bar.
static final String	CIRCLE	Circle inscribed in the node's bounding box (uses min(w, h)/2 as radius).
static final String	CONTAINER_WITH_HEADER	Rounded-rect container with the label anchored to its top edge (header band) instead of the centre.

Field Details

ROUNDED_RECT

public static final String ROUNDED_RECT

Rectangle with rounded corners. Generic "block" / "action" look.

• Constant Field Values

RECT

public static final String RECT

Sharp-cornered rectangle. Use for tables, raw containers, etc.

CIRCLE

public static final String CIRCLE

Circle inscribed in the node's bounding box (uses min(w, h)/2 as radius).

See Also:

• Constant Field Values

DIAMOND

public static final String DIAMOND

Diamond / rhombus — used for decisions, merges, choice points.

• Constant Field Values

BAR

public static final String BAR

Thin horizontal (or vertical, depending on aspect ratio) bar. Used for fork / join markers in process notations.

• Constant Field Values

CONTAINER_WITH_HEADER

public static final String CONTAINER_WITH_HEADER

Rounded-rect container with the label anchored to its top edge (header band) instead of the centre. Use when the node wraps child nodes — the centre is where the children draw, so a centred label would overlap them. Used for if-branch and foreach-loop containers.
