Interfaces
interface AllocationRequest
A request by an app for allocations to be created to enable the execution of a settlement. Apps are free to use a single request spanning all senders or one request per sender. viewtype AllocationRequestView
Choice AllocationRequest_RejectReject an allocation request. Implementations SHOULD allow any sender of a transfer leg to reject the allocation request, and thereby signal that they are definitely not going to create a matching allocation for the settlement. Controller: actor Returns: ChoiceExecutionMetadata Choice AllocationRequest_WithdrawWithdraw an allocation request as the executor. Used by executors to withdraw the allocation request if they are unable to execute it; e.g., because a trade has been cancelled. Controller: (DA.Internal.Record.getField @“executor” (DA.Internal.Record.getField @“settlement” (view this))) Returns: ChoiceExecutionMetadata- Choice Archive Controller: Signatories of implementing template Returns: () (no fields)
