captureOperationGroupToken method

Object? captureOperationGroupToken(
  1. TKey operationKey
)

Captures an opaque token identifying the current operation group at operationKey, or null if no group is installed there. The token is only valid as input to isOperationGroupSame — its concrete type is not part of the public contract and may change.

Implementation

Object? captureOperationGroupToken(TKey operationKey) =>
    _operationGroups[operationKey];
