TriggerMetaData

@Serializable

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

Payload for the simple-threshold trigger family.

The interpretation of value depends on the krill.zone.shared.KrillApp subclass the node is wearing: for HighThreshold it is the upper bound, for LowThreshold the lower bound

Default name uses the class's simpleName so a brand-new node already has a sensible label without the user editing anything.

Constructors

TriggerMetaData

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

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

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.
