Параметры

id  Guid

The unique identifier of the settings unit for which the lock is being established.

shouldExist  NullableBoolean

Indicates the expected existence of the settings unit in the system.

• – The unit must exist
• – The unit must not exist
• – Existence doesn't matter

versionIfExists  Int32

The version number of the settings unit for which the transaction should be opened.

• > 0 – Check the version number only if the unit is expected to exist (ShouldExist is not )
• <= 0 – The version number is ignored; only existence checks may be performed depending on ShouldExist

validationResult  IValidationResultBuilder

An object responsible for building the validation result, indicating the reason why the lock could not be acquired.

cancellationToken  CancellationToken  (Optional)

Propagates notification that operations should be canceled.
