Section titled “Inherited from”Accessors
Section titled “Accessors”correlationId
Section titled “correlationId”Get Signature
Section titled “Get Signature”get correlationId():
string
Defined in: packages/pipeline/src/pipeline.context.ts:34
Immutable correlation ID for distributed tracing: the current correlation
id when the pipeline starts (from @cqrs-ddd/pipeline-correlation, or the
enclosing pipeline), otherwise a new one from the correlation source’s
create() (uuidv7() without one). Nested dispatches
inherit it.
Returns
Section titled “Returns”string
Immutable correlation ID for distributed tracing: the current correlation
id when the pipeline starts (from @cqrs-ddd/pipeline-correlation, or the
enclosing pipeline), otherwise a new one from the correlation source’s

request
Section titled “request”Get Signature
Section titled “Get Signature”get request():
TRequest
Defined in: packages/pipeline/src/pipeline.context.ts:145
The input of this execution, or the replacement a behavior handed in.
Returns
Section titled “Returns”TRequest
The command/query/event instance with all its property values.
Overrides
Section titled “Overrides”response
Section titled “response”Get Signature
Section titled “Get Signature”get response():
TResponse|undefined
Defined in: packages/pipeline/src/pipeline.context.ts:85
The handler’s return value. Read-only for behaviors.
Returns
Section titled “Returns”TResponse | undefined
The handler’s return value, set automatically after the real handler executes.
Available to behaviors in their post-next() code path.
undefined before the handler runs or for event handlers that return void.
Inherited from
Section titled “Inherited from”tenantId
Section titled “tenantId”Get Signature
Section titled “Get Signature”get tenantId():
string|undefined
Defined in: packages/pipeline/src/pipeline.context.ts:48
Active tenant identifier for multi-tenant pipeline executions.
Returns
Section titled “Returns”string | undefined
Tenant of this execution: the current tenant when the pipeline starts
(from @cqrs-ddd/pipeline-tenant, or the enclosing pipeline), which nested
dispatches inherit. Absent when there is none; tenant-scoped behaviors
then fail closed.

Internal
Assigns the ID before the behavior chain starts.
Parameters

[SET_REQUEST]()

Replaces the input the handler receives; see replaceRequest.
Parameters

Returns
Section titled “Returns”void
[SET_RESPONSE]()
Section titled “[SET_RESPONSE]()”[SET_RESPONSE](
value):void
Defined in: packages/pipeline/src/pipeline.context.ts:93
Symbol-keyed setter — only callable by code that imports SET_RESPONSE.
This keeps response effectively readonly for behaviors.
Parameters

Returns

[SET_TENANT_ID]()
Section titled “[SET_TENANT_ID]()”[SET_TENANT_ID](
value):void
Defined in: packages/pipeline/src/pipeline.context.ts:58
Assigns the tenant once per execution. A different value after one is set (by the runner, from the tenant source or the enclosing pipeline) throws, so a behavior cannot move an execution to another tenant after an earlier behavior has used it.
Parameters

getBehaviorOptions()
Section titled “getBehaviorOptions()”getBehaviorOptions<
T>(behaviorType):T|undefined
Defined in: packages/pipeline/src/pipeline.context.ts:115
Returns the options for a behavior on this handler: the options from a
global [Behavior, opts] tuple, shallowly overridden by the options of the
call site’s [Behavior, opts] entry.
