Builder

@ExperimentalWorkflowApi

class Builder<I, O>

Fluent builder for FunctionNode, provided primarily for Java callers. Any property left unset falls back to the same default as the constructor. Java gets one from FunctionNodes.builder or toBuilder, which keep the port types and parallel-worker settings, because a port cannot decode without a type.

Functions

fun body(body: NodeBody<I, O>): FunctionNode.Builder<I, O>

Sets the function the node runs on each input. Required, except on a parallel node, which runs its item node and so build rejects a body for one.

fun build(): FunctionNode<I, O>

Builds the FunctionNode.

fun config(config: NodeConfig): FunctionNode.Builder<I, O>

Sets the node's retry policy and execution timeout. A parallel node runs its items with the item node's config, so build rejects a non-default config for one.

fun description(description: String): FunctionNode.Builder<I, O>

Sets what the node does, for humans and for a model that may call it.

fun inputSchema(inputSchema: Schema?): FunctionNode.Builder<I, O>

Sets an explicit schema that each input must match before the body runs.

fun name(name: String): FunctionNode.Builder<I, O>

Sets the node's name, unique within its graph. Required.

fun outputSchema(outputSchema: Schema?): FunctionNode.Builder<I, O>

Sets an explicit schema that each output value must match.

fun rerunOnResume(rerunOnResume: Boolean): FunctionNode.Builder<I, O>

Sets whether a resume runs the node again rather than using the resuming answer. A parallel node always reruns, so build rejects false for one.

fun stateSchema(stateSchema: Schema?): FunctionNode.Builder<I, O>

Sets the state keys the node uses, which child nodes inherit unless they declare their own.

fun waitForOutput(waitForOutput: Boolean): FunctionNode.Builder<I, O>

Sets whether the node stays re-triggerable until it produces an output or a route.
