Interface ExtBoardOperationResult

All Superinterfaces:

OperationResult

public interface ExtBoardOperationResult
extends OperationResult

The ExtBoardOperationResult interface extends OperationResult to provide specific results for external board operations.

It is used by the external board device implementation to inform an application about the completion status of a requested operation.

The getResultCode() method, inherited from OperationResult, retrieves the result code of the operation. Standard result codes are defined in OperationResult.

This interface also provides additional functionalities specific to external board operations, such as retrieving the data buffer and its length.
