NodeInfo

@Serializable

data class NodeInfo(val path: String = "", val outputFor: List<String>? = null, val messageAsOutput: Boolean = false)

Identifies the workflow-node activation that emitted an com.google.adk.kt.events.Event; null outside a workflow.

Constructors

NodeInfo

constructor(path: String = "", outputFor: List<String>? = null, messageAsOutput: Boolean = false)

Types

Builder

class Builder

Fluent builder for NodeInfo, provided primarily for Java callers. Any property left unset falls back to the same default as the constructor.

Properties

messageAsOutput

val messageAsOutput: Boolean

When true this event's content is the node's output, so no separate output event follows.

name

val name: String?

The emitting node's name: the last segment of path without its run ID, such as a for wf@1/a@2, or null when path is empty. Mirrors ADK Python's NodeInfo.name, which returns an empty string instead of null.

outputFor

val outputFor: List<String>?

The node paths this event's output counts for within its invocation: the emitter's own path, then each ancestor linked to it by useAsOutput (a runNode caller, or the workflow of a terminal node). Set on an event carrying the node's output, in output or as message-as-output content.

parentRunId

val parentRunId: String?

The run ID of the emitting node's parent: the part of path's second-to-last segment after @, such as 1 for wf@1/a@2. Returns null when path has no parent segment or the segment has no run ID. Mirrors ADK Python's NodeInfo.parent_run_id.

path

val path: String

The emitting node's path. Segments are /-separated and each is name@runId, so a node of workflow wf reads wf@1/a@1. An empty path denotes the workflow's top-level node.

runId

val runId: String?

The emitting node's run ID: the part of path's last segment after @, such as 2 for wf@1/a@2, or null when the segment has none. Mirrors ADK Python's NodeInfo.run_id, which returns an empty string instead of null.

Functions

toBuilder

fun toBuilder(): NodeInfo.Builder

Returns a Builder initialized with this instance's properties, primarily for Java callers. Prefer it over copy from Java: copy takes every property positionally, so its signature changes whenever a property is added.
