Class: SequenceBuilder

Defined in: src/core-flow/Sequence.ts:285

Fluent builder. Reads as natural English: Sequence.create().step('a', A).pipeVia(fn).step('b', B).build() → "Sequence: step A, pipe via fn, step B."

step(id, runner) adds a sequential step. pipeVia(fn) customises the transformation of the previous step's output before it feeds the next step (otherwise the default string-chain mapper is used).

Constructors

Returns

Returns

Sequence

pipeVia()

pipeVia(fn): this

Defined in: src/core-flow/Sequence.ts:332

Transform the previous step's string output before it reaches the next step. Consumed once by the next .step() call. Default mapping is (prev) => ({ message: prev }).

Reads as English: .step('a', A).pipeVia(fn).step('b', B) → "step A, pipe via fn, step B"

Parameters

fn

(prev) => object

Returns

this

step()

step(id, runner, opts?): this

Defined in: src/core-flow/Sequence.ts:306

Add a step. Runner must accept { message: string } and return string. First step receives the Sequence input; subsequent steps receive the previous step's output (via the default string-chain mapper, or via the transformer set by a preceding .pipeVia(fn) call).

Optional third arg opts.groupTranslator overrides the runner's own constructor-level translator for THIS step only — only its member.uiGroup flips to the override's output.

Parameters

id

string

runner

StepChild

opts?

SequenceStepOptions

Returns

this
