DiagramMetaData

@Serializable

data class DiagramMetaData(val name: String = "Diagram", val description: String = "", val source: String = "", val anchorBindings: Map<String, String> = emptyMap(), val error: String = "", val sources: List<NodeIdentity> = emptyList(), val snapshot: Snapshot = Snapshot(), val invocationTriggers: List<InvocationTrigger> = emptyList(), val nodeAction: NodeAction = NodeAction.EXECUTE, val inputs: List<NodeIdentity> = emptyList()) : SourceMetaData(source)

Payload for a Diagram node.

Constructors

DiagramMetaData

constructor(name: String = "Diagram", description: String = "", source: String = "", anchorBindings: Map<String, String> = emptyMap(), error: String = "", sources: List<NodeIdentity> = emptyList(), snapshot: Snapshot = Snapshot(), invocationTriggers: List<InvocationTrigger> = emptyList(), nodeAction: NodeAction = NodeAction.EXECUTE, inputs: List<NodeIdentity> = emptyList())

Properties

anchorBindings

val anchorBindings: Map<String, String>

Mapping from SVG anchor id (k_* data attribute on an SVG element) to the node id whose live state should be overlaid on that element.

description

val description: String

Optional free-form description shown in the editor's info pane.

error

open override val error: String

Last known error message for this node, or empty string when healthy.

inputs

open override val inputs: List<NodeIdentity>

sets the nodes this node reads from to complete its work when invoked

invocationTriggers

open override val invocationTriggers: List<InvocationTrigger>

The set of InvocationTriggers configured to wake this node. The node processor checks the incoming event against this list before doing any work. An empty list means "never auto-fire" — only manual execution.

name

val name: String

Display name shown on the project chip and in the editor.

nodeAction

open override val nodeAction: NodeAction

The action this node performs when it fires. Defaults to NodeAction.EXECUTE on every concrete implementation so that deserialising a payload that predates this field yields the original behaviour unchanged.

snapshot

open override val snapshot: Snapshot

Stores the last result of when this node was invoked and is a source of data

source

val source: String

Filename of the SVG inside the server's diagram directory.

sources

open override val sources: List<NodeIdentity>

Upstream nodes whose values feed this one. For a filter or executor this is the data being read; for a trigger it is the value being watched.
