GraphMetaData

@Serializable

data class GraphMetaData(val name: String = "", val sources: List<NodeIdentity> = emptyList(), val snapshot: Snapshot = Snapshot(), val timeRange: ComputeTimeRange = ComputeTimeRange.HOUR, val invocationTriggers: List<InvocationTrigger> = emptyList(), val nodeAction: NodeAction = NodeAction.EXECUTE, val error: String = "", val inputs: List<NodeIdentity> = emptyList()) : SourceMetaData(source)

Payload for a DataPoint.Graph node.

Implements SourceMetaData for consistency with the other source-bound node types, but only sources is meaningful — graphs read data, they don't write it. targets is kept empty.

Constructors

GraphMetaData

constructor(name: String = "", sources: List<NodeIdentity> = emptyList(), snapshot: Snapshot = Snapshot(), timeRange: ComputeTimeRange = ComputeTimeRange.HOUR, invocationTriggers: List<InvocationTrigger> = emptyList(), nodeAction: NodeAction = NodeAction.EXECUTE, error: String = "", inputs: List<NodeIdentity> = emptyList())

Properties

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. Empty string falls back to "Graph" in krill.zone.shared.node.name. The previous default of "Data Graph" produced indistinguishable siblings under different parent DataPoints; callers (UI, MCP) are expected to supply a parent-derived name like "<parent> graph" at construction time.

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

Not used for graphs but required by the SourceMetaData contract.

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.

timeRange

val timeRange: ComputeTimeRange

Lookback window the graph displays — drives the X-axis range.
