Constructor JobHandlerRegistry

Namespace

MailFathom.Application.Jobs.Execution

Assembly

MailFathom.Application.dll

JobHandlerRegistry(IEnumerable<IJobHandler>)

Indexes the handlers this process registered.

public JobHandlerRegistry(IEnumerable<IJobHandler> handlers)

Parameters

handlers IEnumerable<IJobHandler>

Every handler the composition root supplied.

Remarks

Two handlers for one type are refused rather than resolved by order, because either could be the one meant and choosing silently would make which one runs depend on registration order. It is a defect in how the process was composed rather than a condition a run can recover from, so the refusal is raised where it is noticed rather than absorbed into an outcome.

Exceptions

ArgumentNullException

Thrown when handlers is null.

ArgumentException

Thrown when a handler names the unspecified job type, or when two handlers name one type.
