SerializationContext <T>

Helper that allows to keep track of where we are currently at when serializing complex entity graph with cycles. Before we process a property, we call visit that checks if it is not a cycle path (but allows to pass cycles that are defined in populate hint). If not, we proceed and call leave afterwards.

Methods

close

• close(): void

• Returns void

leave

• leave<U>(entityName: string, prop: string): void

• Type parameters

  • U

  Parameters

  • entityName: string

  • prop: string

  Returns void

visit

• visit(entityName: string, prop: string): boolean

• Parameters

  • entityName: string

  • prop: string

  Returns boolean

staticpropagate

• propagate(root: SerializationContext<Partial<any>>, entity: Partial<any>, isVisible: (meta: EntityMetadata<any>, prop: string) => boolean): void

• When initializing new context, we need to propagate it to the whole entity graph recursively.
